Candlewood Lake Study DocumentDescription
Engineering AgreementEngineering Agreement:
Download the engineering agreement and work plan approved by CT DEEP for a 55% Clean Water Fund Planning Grant. The purpose is to develop the sewer system designs for the Candlewood Peninsula and Dean Road areas at a greater cost-share by the state than the conventional 20% Clean Water Fund construction grant—a savings to Brookfield of over $500,000. The 45% difference will be provided in the form of a loan from the WPCA to be repaid when the project is funded by a Bond.
The field work starts second quarter 2022
