Wastewater Treatment Plant

The wastewater treatment plant is operated under the supervision of the Department of Public Works.

The wastewater treatment plant was constructed in the early 1970’s to eliminate the sewage from entering directly into the bay. It was designed as an extended aeration style process plant, using chlorine to kill bacteria before entering the bay.

The plant has recently been upgraded to a new system called sequential batch reactor, which processes the influent using a ultra-violet light system to kill the bacteria prior to outflow.

Current rates and payment due dates are periodically updated in the Village Code.
