Settling ponds are being constructed by Weyher Construction Con-struction Company. material present in the water after tne purification process. If, for some reason, water does not meet EPA standards, an alarm sounds and the control panel lights up. The system monitors all of the three plants in the Davis County area. Mr. Hensley said that even with this sophisticated monitoring equipment, the water district continues to test the water every two hours. 'ANYTHING mechanical can go wrong so we double check," he said. Federal guidelines now specify that any suspended suspend-ed organic matter in the water cannot exceed one part per million. These standards stan-dards are more strict than the five parts per million turbidity allowed previously. When the raw water is taken from the Weber River, it goes to the settling basins which are now being doubled in size. There the flocculation process goes on. Aluminum sulfate is added to the water. Large paddles turn the water as snowflake-like particles of aluminum sulfate precipitate out, taking with them the sediment present in the water OTHER chemicals such as chemically activated carbon, which removes the taste and odor, and potassium permanganate, which removes the iron and the manganese man-ganese are added to the water. Chlorine is also added. According to Mr. Henseley the next process in the water plant is the filtration process. The plant where the water is filtered fil-tered is also being expanded to double the purification capacity. When completed in May, the filtration plant will duplicate in size the other Weber Basin Plant which was constructed 21 years ago. Any excess particles which are not settled out, are filtered out. Anthracite coal and silica are used as a filter media. A new concept in the removal of sludge is the Leopold Clarivac system which employs the use of a small cable which floats on the top of the water. According Ac-cording to Mr. Hensley this system is unique to Utah where Weber Basin will use the method for the first time in the new plant. The water purification process, which taVes two hours from start to finish, relies on the three mehtods of purification: flocculation, sedimentation and filtration. When the clean water is chlorinated, it is then stored in four underground reservoirs reser-voirs before being piped to the distribution distribu-tion points. ' "OUR objective is to produce water of a quality which will meet federal and state standards," Mr. Hensley said. Forty full-time full-time employees of the water district provide culinary as well as irrigation water in the five county area serviced by the water district in Box Elder, Weber, Summit, Morgan, as well as Davis County. The secondary irrigation system saves residents money since only drinking water goes through the complete purification process. Almost everyone agrees titday that smoking is bad for your health.
