1. Notice of EIE for Mattabassett District Water Pollution Control Facility Upgrade
Municipality where project is proposed: Cromwell
Address of Project Location: 245 Main St., Cromwell
Project Description: The Mattabassett District Water Pollution Control Facility upgrade will allow the facility to meet its service requirements through 2030. This upgrade will provide for greater control of nitrogen removal and prepare for projected growth in the plant’s service area. Specifically, the proposed work will include modifications of the existing four aeration tanks and the construction of two additional aeration tanks, two additional secondary clarifiers and a side stream reactor to treat solids handling recycle flows prior to discharge to the secondary treatment system. The side stream reactor will require construction of a new pump station to transfer solid handling recycle flows. There will be modifications to the Return Activated Sludge (RAS) pumping system to pump RAS from the existing and new secondary clarifiers to the sidestream reactor. A new primary effluent splitter structure to provide even flow split to each of the six aeration tanks will be required. The project is designed to allow for continual operation of the facility while the expansion and upgrades are implemented.
The proposed expansion from 20 to 35 million gallons per day average daily design capacity and upgrade work is for service area growth issues and the need to provide advanced wastewater treatment for nutrient removal. There are significant expansions of the sewer system due to allotments requested by the District’s member communities and contract communities and the planned connection of Middletown’s wastewater flows. The project will result in improved plant efficiency, reliability and positive environmental benefits as a result of improved water quality to the Connecticut River and Long Island Sound.
