Where does New Haven’s water come from? Ten lakes and three aquifers are the sources of your water. The lakes are filled with rivers. Aquifers are natural sand, gravel, and bedrock areas below the ground surface that are saturated with water, typically from rainfall. Over 80 percent of the tap water in the South Central Connecticut Regional Water Authority’s water district comes from lakes located in Hamden, Woodbridge, East Haven, Bethany, Guilford, Madison, Killingworth, Branford, and North Branford. In contrast, the balance of the tap water comes from the Quinnipiac and Mill River aquifers located in Cheshire and Hamden and the Housatonic River aquifer in Derby and Seymour.

South Central Connecticut Regional Water Authority’s distribution system is interconnected. Water from two or more sources may be delivered to some neighborhoods. This blending of water not only permits South Central Connecticut Regional Water Authority to meet your water demands, especially during a heatwave but readily ensures that water is available to fight a fire or other emergency.
