Implementation of the Greater New Haven Combined Sewer Overflow Long Term Control Plan will clearly dominate the Authority’s agenda for the foreseeable future. The goal is extremely important – to improve the water quality of the West River, the Mill River, the Quinnipiac River, New Haven Harbor and ultimately Long Island Sound.

The benefits include eliminating dry weather overflows and 100% of wet weather overflows for the average annual rainfall, reducing basement backups and street flooding, and protecting critical shoreline areas of greatest public use and environmental sensitivity. Our role is to ensure that we achieve the goal in a way that is both cost effective and affordable. To achieve these results we will continue to seek and obtain the greatest amount of grant funding available for this project.

We are actively implementing the program and have completed all short-term projects and goals. In the future, you will continue to see improvements to our sewer system occurring throughout our region. This is just one more way the GNHWPCA is doing its part to provide you, our customers, with the best service possible. The changes we will make will help protect our environment and improve the quality of life for the region both now and in years to come.
