DEEP: Water Diversion Program

Water Diversion Program

The Water Diversion Program regulates activities that cause, allow or result in the withdrawal from, or the alteration, modification or diminution of, the instantaneous flow of the waters of the state through individual and general permits. The Water Diversion Policy Act is codified in Section 22a-365 through 22a-379 of the Connecticut General Statutes. Sections 22a-372-1 through section 22a-377(c)-2 of the Regulations of Connecticut State Agencies clarify and expand upon certain provisions of the Statute.

In general, any person proposing a diversion which was not previously registered with the Department and, which is not exempt, must apply for a permit. You must apply for a permit if, among other things, you propose to

  • withdraw groundwater or surface water in excess of 50,000 gallons of per day;
  • collect and discharge runoff, including storm water drainage, from a watershed area greater than 100 acres;
  • relocate, retain, detain, bypass, channelize, pipe, culvert, ditch, drain, fill, excavate, dredge, dam, impound, dike, or enlarge waters of the state with a contributing watershed area greater than 100 acres;
  • transfer water from one water supply distribution system to another in excess of 50,000 gallons per day;
  • or modify a registered diversion.

Failure to obtain a permit for an unauthorized diversion may result in the initiation of enforcement actions with injunctions and penalties.
