PLEASANTVILLE, N.Y. -- Officials with the New York City Department of Environmental Protection told village commissioners last week that the planned temporary closure of a massive watershed pipeline will force additional chemical treatment of drinking water at the Pleasantville plant and an expansion of the facility in the coming years, according to the Examiner News.com.
The DEP officials said the Delaware Aqueduct will be closed in 2022 for five to eight months to repair leaks.
To compensate, water flow from the Catskill Aqueduct in Ulster County will be increased, the Examiner New.com said.
The DEP plan is to build an auxiliary building just north of the existing plant in advance of the closure to store the de-chlorination chemical that reduces turbidity. The new building, is planned to open in November 2018, the Examiner News.com added.
The DEP will also be treating water to remove residual chlorine dioxide upstate before it enters the Kensico Dam and liquid sodium bisulphate will be used before and during the Delaware shutdown, the Examiner News.com reported.
Neither chemical is hazardous to the public.
