Sand as filter media meets most exacting standards of water treatment and purification systems and swimming pool filtration. In Athens, New York, they used a slow sand filter system since 1980 and it worked fine for the community however, it is no longer structured for rapid sand filter system which is now being used. They have to backwash more frequently because the lagoon is filling up more quickly.
Residue from the water filtration system goes into a lagoon that is badly in need of a major cleanup. The lagoon has not been cleaned for a number of years and it contains suspended solids. There is a thick substance-like mud that ends up at the bottom of the lagoon and it is interfering with the functionality of the system.
The water filtration plant has two lagoons, a large one and a smaller one. Some of the impurities that are sent to the larger lagoon end up in the smaller lagoon that becomes overloaded. Last summer, village employees made quick repairs but it was not enough. A heavy rainstorm even made matters worse.
One of the walls of the lagoon broke open and some of the materials it contained flowed down the hill. This meant a notice of violation from DEC. DEC is currently working on the necessary steps that the village must undertake to be able to comply with regulations. It would mean cleaning the two lagoons and building a third one.
Dealing with the two lagoons including the construction of the third lagoon will cost approximately $700,000. The project will also require additional expenses for the upgrading of the electronic system and cleaning out the filtration system’s carbon filters. A resolution will pave the way for the village to take out a series of bonds amounting to $1 million so that mandated improvements can be undertaken.
According to DEC’s present timetable, the village only has until December 1 of this year to clean the sludge from the two existing lagoons. The village needs to submit engineering plans for the third lagoon by March 1, 2016 and for the lagoon to be completed by December 31, 2016.
