About Our Water

Water Sources and How We Protect Them

Protecting the water supply at its source is the first step in achieving the water department’s goal of providing safe drinking water to its customers.

The District’s reservoirs, located in Lewisboro, NY and New Canaan, CT, hold approximately one billion gallons of water. The source of the water is the watershed land covering 10 square miles in New Canaan, Ridgefield and Wilton, CT and Lewisboro, NY. Rainfall and snowmelt from this land are channeled into soils, groundwater, creeks and streams and then into our reservoirs. Disturbance or pollution on watershed land can directly affect the drinking water reservoirs.

Measures to protect the watershed land and reservoirs include daily patrolling of the area. Open communications with both the local police and fire departments in our watershed towns is essential. We also work closely with local government focusing attention on new land development in our watershed. When necessary we actively oppose unsuitable development.

Each year our water treatment operators visit the properties on the watershed as part of our sanitary survey requirement.Procedures to protect our groundwater sources in the Kellogg-Deering well field continue through the Aquifer Protection Area Regulations.

The Norwalk Zoning Commission has used its authority to register and regulate businesses that pose a potential risk to our drinking water. The commission continues to provide updates to the registrations and work closely with the water department with regard to protection of our well field.

How FDWD Water Is Treated and Purified

The reservoir water is filtered at our treatment plant in New Canaan. The filtered water is then disinfected with chlorine to protect against any bacteria still present. We carefully monitor the amount of chlorine, adding the lowest quantity necessary to ensure the safety of your water without compromising the taste.

Finally, chemicals are added to adjust the acidity and protect the water pipes, and fluoride is added to prevent tooth decay. At the well field, the groundwater is filtered naturally by sand and gravel. The water is then treated in a similar manner as the surface water with the addition of aeration which removes contaminants and raises the pH.

Conserve Water and Save Money

Water is a precious commodity that we can preserve with some simple steps...

Indoors

  • Repair faucet and toilet leaks
  • Take shorter showers and shut off water while shaving or brushing teeth
  • Replace old fixtures with new water saving devices
  • Keep water for drinking in the refrigerator
  • Run dishwasher and washing machine only when full

Outdoors

  • Water the lawn and garden in the early morning to avoid evaporation
  • Check that sprinklers don’t leak and that they water the lawn and not the pavement
  • Use mulch around plants and shrubs to reduce evaporation
