Violation Reporting

If you are required to submit a violation report by a permit condition, please use the Violation Reporting Form to detail the violation and steps taken to prevent a reoccurrence of the violation. A completed and electronically signed form may be emailed to the Consumptive Water Diversion Program at DEEP.WaterUseReport@ct.gov.

Exemptions
If you were required to obtain a permit for a non-consumptive use, such as a stream channel alteration, culvert, or pond dredging, please consult your permit for any reporting or notice requirements.  No reporting is required for a non-consumptive diversion registration such as a stream channel alteration, impoundment, or culvert.

If you operate a consumptive diversion where water is withdrawn and removed from its native location, but withdraw less than 50,000 gallons of water during any 24-hour period and will not exceed that daily volume, you are exempt from the requirements of the Water Diversion Policy Act and not required to report. 
 
Discontinued Diversions
Please contact the DEEP Water Planning and Management Division at (860) 424-3704 or DEEP.WaterUseReport@ct.gov if you have permanently discontinued your registered or permitted diversion, or sold or transferred the diversion to another party, so that we may update our records.
