With the most populous of all African nations and a per capita automobile ratio second to none in the world, this Atlantic coast country has only within the last 10 years risen from strife of the Moslem -Christian War and military rule. Patterned on the U.S. form of Federal/ State Government, a new capitol city is be- ing constructed which will use present build- ings in Lagos (current capitol) as models for Government Ministries. In addition, similar buildings will be constructed as capitols in each of 19 states. Currently, the National External Affairs Ministry headquarters building in Lagos, with approximately 1,500 workers, is being served by a 16,000 gallons per day Croma- glass wastewater treatment system as part of Nigeria's pollution control programs. Up until now, city sewage was discharged into open sewers along the streets, which in turn empty directly to the ocean. Conforming with Cromaglass Policy that all such projects be supervised by central office technical personnel, I. E. Udoh, Man- aging Director of Cromaglass Distributor, Zwischenstuck Engineering, contracted for E. J. Wilson, Cromaglass Midwest U.S. rep- resentative, to oversee this installation. When interviewed upon return, Ed Wilson Cromaglass 8,000 GPD system contains 900 gallon comminution tank, flow splitter tank, and 3 - 2,500 gallon modular treatment tanks. commented on the challenging nature of his visit to Lagos. Initially, location for all tanks of the system was in concrete pits which due to tidal water incursion had to be con- stantly pumped until the tank modules were placed and secured with tiedowns and a cover of sand (to prevent floating).

He par- ticularly noted the lack of good tools consid- ered necessary elsewhere and the commu- nications problems with local Nigerian plumbers and electricians. Speed of work during Ed's stay was helped, he said, with the type of "packaged" module furnished by Cromaglass which consists of fiberglass compartmentized tanks to implement the special batch type process. Each of two similar 8,000 gallon systems is located at opposite ends of the nine story glass faced building —allowing flexibility of use should special maintenance be required. As incorporated in most Cromaglass Sys- tems, pumps automatically discharge treat- ed effluent under pressure through a solid- state disinfection unit to the adjacent bay waters. 27=6."

Owned and administered by Arthur Cook, as Chairman, and Philip, his son as President, they constructed a beautiful industrial/ commercial type building that blended well with the surrounding topography and en- vironment. Unfortunately, their sewage system had been inadequately designed and they had been over the last couple of years encoun- tering a slimy, smelly drainage of septic sewage into the front area of their property with eventual runoff through a drainage sys- tem to the nearby woods. Having heard of Trimm Building Corpora- tion's ability to design, install, and service Cromaglass aerobic wastewater treatment systems, Phil Cook contacted Hershel Trimm for help. Trimm and his engineering consultants analyzed site conditions and determined that first of all, the treatment tank should be sized to handle a daily flow of between 4,000 and 5,000 gallons including surge or peak loading. Next, a decision was made to abandon the current septic tank drain field area and to pipe treated aerobic effluent across an access road to the wooded area where a few trees and brush would be removed al- lowing installation of approximately 3,850 linear feet of perforated 4 inch drain line. To accommodate the latter, it would be neces- (Continued on page 2) Builder Diversifies To Overcome Housing Recession W. Hershel Trimm, past President of the Ala- bama Builders Association and a National Director of NAHB, saw the need for improved alternatives to central sewers. Through his Trimm Construction Company, headquartered in Birmingham, Alabama, he organized a program acceptable to the Alabama Health Department which would permit him and other contractors in the state to build in lo- cations inaccessible to central sewers or unacceptable for conventional septic tanks. Over a period of three years, installations were made using Cromaglass batch treat systems with integrated pressure dosing capabilities. These were placed in soils or slopes where septics had previously failed, with monitoring of the tanks and drainfields a critical part of the Health Department's re- quirement. Throughout this "onsite" demonstration period, Trimm coordinated his wastewater management program with Mr. Cecil M. Cork, of the Division of General Sanitation, under the Alabama Department of Public Health. As an initial step, the Trimm organi- zation carefully prepared, in cooperation with the state, legal documents that assure best possible maintenance of all installed and operating systems. This includes man- datory periodic inspection with unrestricted access to sewage treatment facilities and payment guarantee for all parts and labor provided by service personnel. A most important aspect of the observa- tion was proof that aerobically treated efflu- ent could be safely discharged to soils types knowingly unacceptable for septic tank/ drainfields. This was accomplished by look- ing and probing into inspection ports strate- gically placed at or near the ends of effluent drain lines. Trimm initially installed Cromaglass batch treat systems on individual home sites, but expanded into use for multi -family and com- mercial properties such as a foster boy's home, an auto dealership, and a lumber company. Two of the more prominent pro- jects have been described and illustrated in this digest. Le Richelieu Town Homes four unit complex Le RICHELIEU TOWN HOMES Developing town homes on 10 acres of ground in the Birmingham, Alabama area was not going to be as economical as Trimm Building Co. originally planned. Due to topo- graphical and soils conditions, tougher Health Department regulations would per- mit construction of only 16 town homes on the 10 acres. However, this did not deter Hershel Trimm in his quest to utilize better on -site technol- ogy for more efficient construction on his property. A more careful analysis of soils conditions by digging deep observation pits indicated that the shaley layer approximately 2 feet below grade was of a porous tight sand na- ture that was easily fractured and, therefore, could support infiltration of a good secon- dary treated type wastewater effluent. Next, Trimm had an engineering study made by Charles G. Bueltman, P.E., of the Cromaglass aerobic systems, to assure the Jefferson County Health Department that the proposed treatment system had the oxy- gen transfer capability to meet the demand of daily wastewater flows from 4 town homes. Engineer Bueltman satisfied himself of treatment capabilities by reviewing tests performed on oxygen transfer utilizing the Cromaglass venturi nozzle processes and by evaluating long-range testing of the Cromaglass System performed at Pennsyl- vania State University Sanitary Engineering Facilities and monitored by the National Sanitation Foundation. Finally, he equated this information with the expected maximum daily biochemical oxygen demand loading (Continued on page 3) SEWAGE PROBLEMS (Continued from page 1) sary to construct a distribution box connect- ed to the drain lines by approximately 1,450 linear feet of 2" PVC solid pipe using over 100 PVC fittings for final connection to the perforated drain line. Among details for completing the installa- tion, it was necessary to coordinate connec- tion to the new Cromaglass Model CA-50 batch -treatment tank with the working - schedule in the building, which except for Sundays, is on an around the clock basis of 3 shifts. The drain field area had been con- structed several days previously and the tank was put into place near the building on a Friday afternoon and Saturday. Installation of pumps and controls was early Monday and coordination of sewer line connection to the new tank during afternoon break for shift change. Due to the "packaged" nature of the Cromaglass System, this transition was car- ried out very smoothly with aerobic effluent being pumped to the new drain field with minimum complications. Trimm's expertise in installing modern wastewater treatment facilities has been of great service to the customer and has ena- bled a home builder, such as he, to over- come problems of the recession in his in- dustry.

A -A Le RICHELIEU TOWN HOMES (Continued from page 1) from each 4 unit town home complex. Other factors influencing the Health Department's decision to permit more housing units per acre, included the use of water saving plumb- ing fixtures and the effect on soils by the discharge of aerobically treated effluent containing less pollutants and a higher oxy- gen content. It was also noted that the aerobic tank ac- cepted for the project contains an integrated discharge/dosing component which enables treated water to periodically be pumped to a higher elevation where subsurface aerobic drainfields have been placed. As an added advantage, inspection ports are included within the drainfield area that can be used as desired to monitor subsurface conditions. As a result of the engineering study, the County Health Department permitted Trimm to construct 43 town homes on the same 10 acres where they would have allowed only 16 with septic tanks as the sewerage fa- cilities. From an economical standpoint, Trimm's gross income, with each town home, aver- aging $95,000 sales totaled over 4 million dollars compared to approx. 1.5 million dollars if the project had been constructed utilizing septic tank systems. In the final analysis, Trimm stated that this made the dif- ference of his deciding whether or not to build the town homes. 1 P" SOLID P.V.C. CROMAGLASS AEROBIC WASTEWATER TREATMENT UNIT.

Extraordinary Installation Bundy Sewer and Drain Ser- vice of South Burlington, Ver- mont installed the unit pictured to the right at the vacation home of Mr. Richard Hurd. Previous to the Cromaglass installation wastewater from the house dis- charged via a four inch sewer line to the water of Lake Cham- plain. Effluent is now treated aero- bicly and pumped to a pollution abating absorption area. With the help of Mr. Hurd, as Chair- man of the local Homeowners Association, Bundy is install- ing progressively more Croma- glass Systems along the shore of the lake. Utilization is being made of built-up absorption beds for disposal of effluent from many of the Cromaglass Sys- tems. Bundy reports that the pumping systems included in the Cromaglass Model C-5 are the key to this type of effluent dis- posal. Bermuda Installation used for Recycling Cromaglass Dealer, Lionel Williams, Williams Plumbing and Heating Company of Hamilton, Bermuda, puts final touches to an installation of a Cromaglass Model C-5 recently made on the semi -tropical mid -Atlantic para- dise. Treated effluent from the system is piped to a holding tank from which it is pumped for use as a flushing medium in toilets. It is anticipated that the same effluent will later be used for watering gardens.

N.A.S.A. has required these in- stallations as part of a program initiated by the Federal Govern- ment to require secondary treat- ment of wastewater flows from all Federal Government facilities. SEE UPDATED REPORT INSIDE All Cromaglass installations at N.A.S.A. were used as replace- ments for malfunctioning septic tanks originally installed — and ef- fluent pipes from Cromaglass tanks were connected directly to original absorption areas that had mal- functioned when preceded by septic tanks. N.A.S.A. has been previously and indirectly involved with Cromaglass products through Jack R. Lousma, one of the three astronauts recently returned from Skylab II. Colonel Lousma installed a Cromaglass system in his suburban Houston residence partly, in his words, "to deter- mine future usefulness in space." OTHER AGENCIES For the past few years Croma- glass has been a supplier of the same type systems to other governmental agencies including the Federal Aviation Administra- tion (for installation at monitor- ing stations), U. S. Coast Guard (coastal stations), and the United States Park Service. F.A.A. Approximately thirty Croma- glass Model CA610 or Model C-5 systems have been installed or ordered for the Federal Aviation Administration facilities. Two major contractors for the F.A.A. have been Hunt Building Cor- poration of El Paso, Texas and Avco International Services Di- vision of Cincinnati, Ohio. NATIONAL BUREAU OF STANDARDS Cromaglass is also active as part of an industry program working with the National Bur- eau of Standards in Washington, D.C. toward national codes and regulations covering individual aerobic wastewater treatment systems. Dr. Jack Snell is direc- tor of the National Bureau of Standards project. Cromaglass executives state that Federal agency specifica- tions for its Wastewater Treat- ment Products appears to be a forerunner of Federal, State and local requirements for nothing less than secondary or tertiary treatment of liquid wastes.

As a result, there is a growing need for accepta- ble alternatives. Cromaglass has continued to engineer its products to provide treatment capabilities for those medium range flows of buildings or fa- cilities located beyond conventional sewers. Largest modules now available from Cromaglass are of the 12,000 gallon capaci- ty dual tank system. In designing these mod- ules, engineering consideration was given to transportation requirements from factory to job site. This meant holding to a maximum 20' length and under 8' width to accommo- date over the road trailers and containers. Community - Cluster Systems Developers and builders have found 4 INTAKE - hi / GOL1D5 RETENTION SECT ION 4,1O2 : 2 AIR INTAKE r AERATION SECTION Cromaglass community type wastewater programs to be very cost effective to the point that on a per home or multi -family resi- dence the tptal system including pump sta- tions, treatment unit, and effluent disposal method ranges down to as low as $1,500— in some cases even lower than costs for un- acceptable septic tanks. Important is the fact that these communi- ty systems are more acceptable to regulato- ry agencies due to better assurance for op- eration and maintenance (responsibility re- tained by one entity). Actual experience with establishment of community systems by builders and devel- opers has provided necessary legal agree- ments binding property owners to assure regulatory agencies that, through local mu- nicipalities, responsible wastewater opera- tion and maintenance programs will always be effective.

Resort areas present a special need for adequate wastewater treatment —due to land values and absolute requirement for a pollution free environment. Discriminat- ing guests will not tolerate poorly run facili- ties. VIRGIN ISLANDS Bitter End Yacht Club is a sailor's delight and major stopover for boaters cruising the northeastern Caribbean area. Isolated on a small remote peninsula of Virgin Gorda with steeply rising mountain sides, the resort is dependent upon rain water collected from rooftops and stored in cisterns. As a result, lack of rain necessi- Cromaglass has enabled many hotel and condominium projects, not only to prevent pollution, but also to provide valuable fresh water for irrigating vegetation and in some cases, toilet flushing. Outstanding feature of Cromaglass units since the owners decided to continue their method of toilet or "black water" disposal using salt water flushing and seepage pits in sandy soil, therefore denying important bio- logical matter to the Cromaglass systems for improvement of treatment efficiency and effluent quality. As a part of its customer ser- vice program Cromaglass provided the con- sulting expertise of representative, Edward BITTER END YACHT CLUB tates the use of a small desalinization plant or fresh water barged from the neighboring island of Tortola with water costing from 3¢ to 6¢ per gallon. With abundant, beautiful, tropical flowers planted throughout the complex, fresh water is in great demand so resort manage- ment has utilized Cromaglass wastewater treatment systems and accessory filters to allow watering with recycled treated waste- water or as it is commonly called "grey water". Over time a special grease removal unit has been added to the kitchen facilities and improved pumping and wastewater management procedures have constantly increased effluent quality. An unusual biological problem was en- countered by Cromaglass at Bitter End J. Wilson, who spent considerable time final- izing on -site engineering and hookup. To replace unavailable toilet water, own- ers of Bitter End agreed to provide food preparation and table scrap wastes that would act as a biological catalyst to the aero- bic treatment tanks. Also included to improve effectiveness was a synthetic bacterial en- zyme that could periodically be added as treatment progressed. Following aerobic treatment, effluent from a series of secondary tank units is passed through a specially designed back- wash type sand filter and finally to storage in large fiberglass tanks. Resulting "grey wat- er" has been highly beneficial to growth of the magnificent flowering plants surround- ing Bitter End. for this type use is their completely enclosed tanks —noiseless and odorless —with locked maintenance hatches. For this reason, they have been located adjacent to housing units valued at over $250,000, consequently sav- ing costly piping and pumping stations. CAYMAN ISLANDS Over the past two years, Grand Cayman Island in the British West Indies, has pre- sented Cromaglass with an unusual chal- lenge. After having provided sewage treat- ment systems several years ago for a con- dominium_complex and bank, not much had been heard from this busy banking center located some 150 miles southwest of Cuba. Suddenly, however, all seemed to blos- som with specifications and new orders for Cromaglass treatment units —due in no small degree to past success added to the hard work of representative, Jacques Vin- mont and his distributor/service contractor, Environmental Engineering ,Ltd., adminis- tered by Director, Heber G.

Guests are mostly those on sailboat island excur- sions but some visit the area for vacations without boats. Architect, Peter Pennington, chose Crom- aglass Corporation to supply the total waste- water treatment system including engineer- ing, design, and installation based upon his knowledge of previous Cromaglass installa- tions at Bitter End Yacht Club and others found throughout the Caribbean Islands. Fresh water is generally obtained in the area only from collection on roof tops and stor- age in cisterns —and is therefore scarce and is a very valuable resource. It is the de- sire of the Tradewinds management to have the option of reusing a portion of the waste- water generated. Since toilet flushing will be accommodated through sea water, irriga- tion of plantings must use total fresh water. Design of the wastewater treatment sys- tem is such that tank modules are located near the buildings discharging the waste- water and in that way minimizing the amount of large diameter sewage pipe and number of sewage pump stations. Since there is very limited ground space surrounding the facilities and the soil is not conducive to a conventional septic tank sys- tem, the Cromaglass method was chosen to provide an optimum treated effluent which is acceptable for reuse or discharge directly into the sea. Aerobically treated effluent can at the op- tion of management be valved to storage for reuse after passing through a tertiary treat- ment sand filter or discharged into the adja- cent ocean. Any discharge into the sea at the chosen location is especially critical due to its proximity to the tropical bathing beach and Marine Sanctuary or fish preserve. Special Design Characteristics —It was important to the architects and engineers of Tradewinds that the wastewater treatment system be easily transported and assembled NE on site. Cromaglass systems met this re- quirement. Some of the large fiberglass tanks were shipped unassembled to save freight costs to the Islands and were easily completed by the installation crew Realizing that restaurant wastewater is very difficult to treat, Cromaglass designed the system in order to provide a mix of do- mestic type sewage with the restaurant wastewater in an equalization tank into which a special biological promoting chemi- cal is automatically metered. Another very critical piece of equipment is a special grease removal unit located near the restaurant kitchen to facilitate best possible operation and removal of kitchen greases. To assure an environmentally acceptable treated effluent discharge from the total sys- tem, disinfection is through a unique ultra- violet/ozone process which was chosen based upon its previous success in tropical resorts. It should be noted that effluent disin- fected in this manner eliminates a chemical residual in recycled water thereby protect- ing needed continued natural biological pro- cesses. I tt Costs of the total Comaglass system in- cluding engineering, design, and installation were determined by the designers of the Tradewinds to be the most reasonable for value received and in comparison to compe- titive treatment plants.

Tree house type cottages nestle between giant round boulders termed as one of the worlds exceptional wonders. Cromaglass aerobic treatment units be- came a necessity at Guavaberry since sep- tic tank systems would not work in the hard, clay like soils that start just off the sandy beaches of Virgin Gorda. As owner -operators, the Charles Roy family utilize Cromaglass wastewater treat- ment systems to provide an effluent accept- able for watering vegetation where clay soils would not be conducive to septic tank use. They purchased their first aerobic system to handle the sewage capacity of two cottages and after several years success, chose a later Cromaglass Model CA-15 for use with the four newest houses. Combined aerated effluent from the older tanks and new CA-15 is pumped to a large sand filter for tertiary treatment and dis- charge through a 500 gallon solid state chlorination contact/storage tank for final use in watering plants or even toilet flushing. Attached to the concrete walled sand filter is a small building where electrical controls, air compressors, and other accessories are located. The Roys have advised that an important reason for using Cromaglass products has been the excellent service provided by the company —both on technical advice and spare parts replacement. CAYMAN ISLANDS, (Continued from Page 1) better treatment and disposal was not in- itiated. It was not difficult to convince govern- ment regulators, engineers, and even gen- eral contractors of the usefulness of aerobic treatment units to provide recycled water that would substitute for that made by ex- pensive desalinization methods.

From a technical viewpoint, if a system is not designed for reuse of effluent passed through a filter accessory and disinfection, the treated water is discharged to 30' or 50' deep wells that extend via 4" and 3" diame- ter pipes into subsurface strata and brack- ish water (depth and number of wells depen- dent on overall quantity of water disposed). THE RONAL IIVA C4 (kNkh Cromaglass systems have been installed on buildings in the heart of Georgetown, the capitol of Grand Cayman.

Ecological promptly telephoned Crom- aglass offices in Williamsport, Pennsylva- nia to determine how soon the 6,000 GPD system could be delivered to Hono- lulu. As a result, the 20' long by 71/2' wide cylindrical tank was released on a Thurs- day with trucking to Kennedy Airport in New York for loading on a Pan Am jumbo jet freighter. Final delivery to the custom- er at the Honolulu Airport was made the Sunday of that same weekend. Quite a feat! But, this is all part of rou- tine service provided by Cromaglass to its customers. (Continued from Page 1) the Cromaglass Batch Treatment System. Method of effluent disposal was addressed as it affected subsurface soils require- ments. On Staten Island, those conditions require an excavation for test pits roughly 4ft. square plus a depth necessary to either reach the water table or a layer of sand. When these tests were performed, it was found that water was at a depth of 33 ft., and to break through the clay -type cover, ended with 5ft. depth of sand in the effluent pit. Having completed design for the proper effluent disposal, it was then necessary to have several meetings between the developer's engineer and the New York City Sanitary Engineering Department. Discussions covered such subjects as pump station following collection of the raw sewage from 30-home subdivision and whether a mechanical comminutor would be required for installation prior to the Cromaglass 15,000 GPD System. These problems were not easily solved but Randy Lee was satisfied that his efforts had provided him with a wastewater treatment system that could be installed immediately adjacent to the project's homes (no noise or odors), and he thereby eliminated costs of long collector lines and pump stations. In addition, he had substantial savings in costs of ground and other space that would have been necessary for construction with a conventional sewerage system. OPERATION & MAINTENANCE One of the more important features of choosing Cromaglass Batch Treatment Systems by consulting engineers is the design of the Cromaglass System which allows for easier overall operation and maintenance and supplementary decrease in development of sludge (which otherwise would be difficult to remove and dispose). Following start-up, the owner's service representative, Peter Jurgeleit, found that the Cromaglass design would not allow any disregard of the monitoring system (basically consisting of float sensors and other alert components). Jurgeleit easily installed in the Cromaglass control package a telephone monitoring device whereby a malfunction at any time of day or night would automatically ring into his office and home indicating that there was a malfunction in the aeration or hydraulic transfer system. Since there is adequate reserve capacity in the Cromaglass tanks, he could wait until "on the job" the next day or as appropriate to provide service required. Editor's Note: This part of the Arbutus — Randy Lee Development is important from the regulatory standpoint and is a clear example of how operation and maintenance concerns of regulatory agencies can be avoided with the appropriate monitoring program — which is inexpensive when applied with a Cromaglass Batch System control package. Consulting Engineer for the Arbutus/Randy Lee project was Carmine Procassini, P.E., of Staten Island, New York. Environmental engineering was provided by Carpenter Associates and their administrator, Dr. Raul Cardenas, who is also an Environmental Engineering Professor. Upon completion of the 30-home subdivision, wastewater from which was much more efficiently processed than would have been the case with conventional treatment plant, entire management was transferred to a home -owner's association that was responsible for collection required sewage fees which, in turn, cover the actual services for operating and maintaining the Cromaglass Community Wastewater Treatment System. Control module for 15,000 GPD system - including automatic telephone monitoring device. (Continued from Page 1) Systems designed for small communities or cluster type situations range in capacities from 1,500 GPD up through 100,000 GPD. Modular units of 3,000; 5,000; and 12,000 GPD are popular because of their low capital costs and ability to be used as required (increasing efficiency of biological treatment). Refer to related article on performance evaluation of Cromaglass Systems. An important element contributing to the overall design and acceptabiltiy of such community systems is the method of treated effluent disposal. This can be via non -contaminating subsurfacez dispersion; through special methods of lagoons, spray irrigation, or recycling; and finally, through the less environ- mentally sound method of direct discharge to steams, storm sewers, rivers or tidal waters. Important, of course, with consideration of the first above alternative for effluent disposal is a knowledge of local sub- surface soils condition and whether or not such soils could support dispersion of the treated effluent. Analysis and design of subsurface soil conditions must be accomplished by a knowledgeable soils scientist or engineer. In some situations, although soils under available parameters established may not seem to support effluent disposal, built up aerobic beds with pressure discharge of treated effluent throughout the area has lent itself very well to optimum conditions.

However, easy access to downtown Manhattan, made possible by construction of the Verrazzano Narrows Bridge, has made the Island an appealing residential area for those working in "the City." There is one important "missing Zink" for affordable home construction (former city dwellers do not want more apartments), and that is the lack of sanitary sewers. This problem led developer (and local attorney), Randy Lee, to seek an alternative waste- water program. As a very active member of the National Association of Horne Builders, Mr. Lee found one possible solution while attending an Association seminar where NAHB staff was reviewing alternative sewage systems. In New York State, as is true in many other areas, it is necessary to have a sewage system permit prior to beginning const- ruction of a project, and although developer Lee had a permit for a package treatment plant with direct effluent discharge to a remotely located pond, this design pre- sented several negative aspects. For one thing, if a large conventional package treatment plant had been used, it would have been necessary to build a house -like structure over the tank system to accommodate regulations regarding aesthetic and sanitary aspects dealing with open type treatment systems. (This was expected to cost over $20,000 in itself.) Further requirements of an NPDES permit, or EPA surface discharge license, included that there must be weekly monitoring with appropriate chemical analysis of effluent quality. (This analysis alone without man- power costs was expected to be approx. $15,000 annually.) Pete Jurgeleit, maintenance manager of Arbutus and Cromaglass Vice President, Frank Moltz, observe 15,000 GPD Batch Treatment System serving 38-home subdivision — note location close to homes. Cromaglass presented Randy Lee with a wastewater management program that included enclosed fiberglass tanks with locked maintenance hatchways which would not require a structure to be built over them. (They would be built into the ground with only their manways showing.) Second important part of the Cromaglass program was for subsurface disposal of treated effluent thereby avoiding require- ments of the special surface discharge permit. Being a very astute developer, conscious of all regulations and cost effective procedures, Randy asked Croma- glass to work with his professsional consulting engineer, Carmine Procassini, who would, in turn, produce the necessary drawings and permit applications including (Continued Page 4, Column 1) PUBLIC FUNDING DECREASES BRING NEED FOR ALTERNATIVE SEWAGE TREATMENT SYSTEMS Population growth, in conjunction with decrease in federal funding for municipal sewerage systems, increased importance of developing alternatives which can be cost effective and acceptable overall for public health and our environment. While septic systems with potential for underground water pollution have been the way of the past, small communities are turning to alternatives which are not only more cost effective, but more easily managed and overall more satisfactory from a public health aspect. (Continued Page 4, Column 2) 4 1 DEVELOPMENT USES BATCH TREATMENT SYSTEMS WHERE SEPTICS UNACCEPTABLE A suburban Philadelphia developer had approximately eight acres remaining of property located in western Chester County, PA. As part of an overall development along Saybrook Road, it was decided to divide the property into eight one -acre lots. Since soils in the area would not support individual septic tank systems, the developer was convinced by contractor, Larry Katzmire, to install a small community wastewater treatment system — and although a large septic tank system could have been utilized (total wastewater capacity of nearly 3,000 gallons per day), Katzmire demonstrated the cost effectiveness of a Cromaglass 3,000 gallon batch treatment aeration system. Design was such that treated effluent would be automatically discharged over 500 feet to one of the building lots with a percolation rate of 55 minutes per inch and where a subsurface drainage area would be located. One of the key elements in using the building lot for treated effluent disposal was that with the batch treat aeration sys- tem, the effluent drainage area could be reduced by over 30% — with reduction allowing a home to be built on the same lot. This more than paid for the $25,000 approximate cost of the overall community treatment system. Individual lot values in that location are approximately $30,000 per acre. • 3,000 GPD pumping station and buried collec- tor/effluent transfer lines (note path through wooded area). Cromaglass Vice President, Frank Moltz, and Servicing Distributor, Larry Katzmire, checking solids settling rate of 3,000 GPD community batch -type wastewater system. Consulting enginners, C.E. Moore, Inc., recommended sizing the small community system at 3,000 gallons per day and, as a result, contractor Katzmire furnished the controlled batch treatment system (Model CA-30) as produced by Cromaglass Corporation of Williamsport, PA. These small community treatment units are sub- ject to approval by the County Health Department and State Department of Enviromental Resources (independent laboratory test report on Cromaglass Batch Systems is available on request). Sequence of collection, treatment, and disposal are such that raw wastewater is transported to the Cromaglass System throught a 6-inch collector line and 1/2 h.p. duplex pump station (pump station un- necessary with certain topographical conditions). Treated effluent (tests indicate 96% reduction of BOD and suspended solids) is then pumped from a 1 h.p. duplex pressure dosing system approximately 500 ft. to the disposal field with total area of 3,000 sq. ft. (est. one gallon per sq. ft. per Subdivision Plot Plan showing 3,000 GPD treat- ment system, pump stations and special design remote disposal field. day). Drainage field is constructed with five trenches, each 6 ft. wide and 100ft. long — and since the trenches are located on 10% -12% slopes, the 11/2 inch PVC pipe contains perforations varying in size depending on location of the pipe on the slope. Effluent transport pipe to the disposal field is 4-inch PVC. To accomplish necessary dosing, pumping from the treatment tank is designed for a 44-foot head with a static head actually being 29 ft. Materials used in the aerobic drainfield consist of crushed stone, untreated building paper, and top soil. Pennsylvania Department of Environ- mental Resources has expressed a preference for this type of small community treatment system as opposed to individual lot sewage units — primarily since long- range operation and maintenance can be more easily controlled. In addition, developers have found this type of sewerage system to be cost effective even as com- pared to problematic septic tank/drainfield systems. PERFORMANCE EVALUATION COMPLETED An intensive independent laboratory analysis of the newest Cromaglass batch treatment design was recently completed at Penn State University's Institute of Research on Land and Water Resources in conjunction with the Civil Engineering Department. This program demonstrated that the unique process can produce an effluent quality superior to Federal EPA and state standards for surface discharges. Results of 96% reduction of pollutants (biochemical oxygen demand and sus- pended solids) are accomplished through recently modified batch process system that is simplified by not requiring special tertiary filters normally used on other treat- ment plants. Treated effluent averaged 10 mg/I for both BOD and suspended solids over the six-month test duration: This performance evaluation conforming to National Sanitation Foundation require- ments confirms the ability of these systems to operate in small communities as alter- natives for large treatment plants which have been found by Congressional Committees to be, at times, too costly and inefficient. Evidence indicates that a large number of on -site sewage disposal systems, con- sisting mainly of septic tanks, have failed. As a result, the Federal EPA, state, and local officials are advocating the use of alternative treatment techniques to offset the high cost of large collection systems and centralized treatment. A complete report on the study, or more information, can be obtained from Croma- glass Corporation, P.O. Box 3215, Williamsport, PA 17701.

A key issue to environmentalists has been the septic tank systems installed in 1985 at each rest -room facility with wastewater effluent being dis- charged to large sand mounds. These mounds were to act as a filter for the effluent before it reached the shallow water table. (Until recently, toilet facilities were of the pit privy or portable john variety — visitors liked the new flush toilets much better.) Pennsyl- vania, through its DER, decided to revise design of the septic tank/ sand mounds by utilizing Croma- glass Controlled Batch Systems to treat septic tank effluent prior to pumping discharge to the same mounds. Cromaglass was chosen because DER Water Quality engineers had previously monitored independent testing of the Cromaglass modules by Penn State University's Sanitary Engineering Laboratories under (Cont'd. on Page 2) corrodible fiberglass tanks plus in- dependently tested, high quality treatment has led to the ability to comply with unusual effluent dis- posal techniques.

This treatment system was to handle the wastewater from six cabins and other rest -room facilities located in the park. For prevention of flooding, cabins were built on pil- ings raising them six feet above ground level. This should have eliminated problems with drainage through sewer lines to the Croma- glass tank — except that a 30" cul- vert existed between cabins and new drainfield. Depth of burial for the fiberglass tank then became the only serious engineering problem for the site — and this was overcome by utilizing fiberglass manways and movable electrical conduit prefabricated in the Croma- glass factory. In conjunction with burial depth, the ground water level being approximately three feet from the surface necessitated special in- stallation procedures not usually encountered elsewhere. A 10" con- crete slab was precast to which the 3,000 gallon tank was anchored. But the problem did not end there as there had been a miscalculation of water displacement for the slab/tank combination. Because coral existed in most of the• subsurface area, it was not possible to drive pilings to help with the excavation. Water was constantly pumped from the exca- vation as the tank and slab were lowered into place. However, the contractor, Alonzo Cothron Con- struction Co., had to be very care- ful with every move made due to serious environmental impact (such as where water or silt was pumped, etc.). Cromaglass servicing represen- tative, Edward Wilson, and local distributor, Bruce Edwards provided on -site advice as is usual with all Cromaglass installations. High water table conditions for tank placement next to cabin. It should be noted that one of the more important reasons why Con- nell Associates chose Cromaglass was due to the noncorrodible fiber- glass construction of its tanks which would overcome much of the deteri- orating properties found even in concrete tanks. Noiseless, odor -free operation was beneficial due to closeness of cabins. Low operation and maintenance costs were other factors in the choice of this system, and after a year of use, it has been found that the Parks Service plant operator has indicated need only for repair of two submersible fractional horse- power pumps. No other repairs have been required. ►1cw. CAb1414. COLI6TRUC1100 TYPICAL , C. LCCATIC'.. c!F' et o 4 1 . ` FOR PTAT701„fi1JGeat FRorit...t MM1G1 OVE A.R.Z.A. ; OOP
