NPB Water Supply 1966I JLAIWiEACH , 71� WA r E...,,R s u...P..p Li I! Ll - DEEP WEELS WITH A MODERN EFFICIENT WATER PLANT PROVIDE THE VILLAGE WITH THE FINEST WATER IN PALM BEACH COUNTY The Water Plant is located west of the Village of North Palm Beach, on Richard Road. It was originally constructed in 1956 with a capacity of 1.5 million gallons per day, and expanded in 1962 to 6 million gallons per day. Water is taken from 11 wells, aerated, chlorinated, softened, sta- bilized and filtered. All phases of treatment are carried out in a Per- mutit precipitator softening unit. This softening unit is - divided into primary and secondary mixing and clarification zones. Water from the wells is first aerated and passes downward through the primary mixing zone of the precipitator; here the water is softened with chemical hydrate lime. After the application of lime for softening, the water rises to the secondary mix where the softening reactions are completed and coagu- lation of lime sludge is started, using activated silicate as a coagu- lant aid. Here also chlorinaation is accomplished. In the clarification zone the co- agulated lime sludge drops to the bottom of the unit, the treated water passes by gravity to five rapid sand filters.. On the way to these filters calgon is added to stabilize the softened water. The water is then filtered and stored in the million gallon ground storage tank and clear well until needed in the Village. The lime slurry which falls to the bottom of the unit is drawn off every two hours or as required by the percentage of the lime needed to soften the water coming into the plants. The lime feeder has a capacity of 1200 lbs. per hour, which feeds to the unit in parts per million; an average day's run of 3600 gallons per minute would require between 4500 and 5000 lbs. of lime per day for softening purposes. The laboratory at the Water Plant is equipped to run complete chemical analyses and a qualified chemist and operators are on duty at all times. Tests are run every two hours. These tests consist of a pH, alka- linity, iron content, total hardness, chloride determination of raw water, color and chlorine. The re- sults of these tests are recorded once a day and filed with the Board of Health once a month. The effluent from all treatment units is checked by the operator every two hours and recorded on daily log sheets. EMERGENCY POWER: In case of power failure, the plant is equipped with a 200 K.W. emer- gency generator, driven by a gas powered Waukesha engine. This is capable of running the plant at 2/ 3 capacity. LIL OR Eli @ HIGH -SERVICE PUMPS. There are 4 High -Service pumps at the plant which have different ratings. 2 1500 gal. per minute pumps 1 500 " 1 3500 " These pumps are capable of de- livering 6500 gallons per minute to the entire system. Our elevated storage tank has a capacity of 300,- 000 gallons which maintains a static head of pressure in our en- tire system of 54 lbs. AREAS SERVICED. North Palm Beach Utilities also serves the town of Lake Park, some parts of Palm Beach Gardens, including Alamanda School, Hidden Key, Hidden Key North, and Lost Tree Village. Our distribution system consists of 72 miles of pipe from 4 -inch to 16 -inch. There are also 264 fire hydrants in the system. Our goal in the past ten years has been to supply our customers with the highest quality water that can be produced, along with the best service available, and this will be our continuing goal in. years to come.
