City hears recommendations for possibly $5 million filtration plant
NORWICH – For months now, City of Norwich Department of Public Works Superintendent Carl Ivarson has been warning officials about the city’s outdated current water filtration system, and the need to begin planning for a new system.
After contracting Stearns & Wheler Engineering for $39,000 to look at conceptual designs for a new system, the city has received a technical memorandum from the company, recommending specifications for the project. The contractor examined the plant’s capacity and water quality for the filtration facilities, and made recommendations based on estimates for demand and current regulations.
In an earlier meeting, Mayor Joseph Maiurano said that city officials were meeting with different legislators. “We’re trying to make sure we’ll have the funding in place so there is no burden on the taxpayers,” the Mayor said. The project could cost in excess of $5 million.
The city’s water supply is Chenango Lake in New Berlin - which consists of the majority of the surface water supply - the upper reservoir, the lower reservoir and two wells to supplement. Stearns and Wheler noted that in the last 20 years, the overall population in the city and town, and in the town of North Norwich, has decreased. No considerable growth is forecasted for the area, however the company allowed for light industrial, commercial and residential growth in their plans for the water system.
According to the report, recommendations for the filtration system are based on projected future water use, perception of an acceptable mix of the surface and groundwater, and willingness to rely on groundwater to meet peak demands.
The study concludes that: Filtration will be necessary as part of the new surface water treatment facilities, filtration must efficiently remove total organic carbon (which will require the use of a coagulating chemical) the process of chlorinating water at the lower ravine will be eliminated once the new filter plant and filtered water storage facilities are completed and that the existing corrosion control treatment process is performing well.
The new water filtration plant would be located on a 13-acre site below the reservoir on state Rte. 23. “By having the plant on the top of the hill, the plant could be gravity fed, instead of using energy sources to have the water piped in,” Maiurano previously said.
