The FBRR applies to public water systems that use surface water or ground water under the influence (GWUI) of surface water, apply conventional or direct filtration treatment, and recycle spent filter backwash, thickener supernatant, or liquids from dewatering processes.

This form should be submitted prior to or immediately after any change so that the system is not in violation of operator certification regulations. Certified Operators should ensure that this form is submitted if they are no longer the operator for a system so that the DWS does not continue to hold them responsible for the system’s operation.

Application for a Well Permit Exception

The Regulations of Connecticut State Agencies (RCSA) prohibits a local director of health from issuing a well drilling permit at residential premises where the water will be used for human consumption, or at non-residential premises where the water may be used for human consumption, when a community water system is deemed available within two hundred feet from the parcel's boundary. In some circumstances, an exception to this regulation may be granted. This application is intended to provide the Drinking Water Section with the information necessary to determine whether such an exception may be issued to the Director of Health. Although the Director of Health is the applicant to the Department, the application has streamlined the process by allowing the affected parcel's owner to gather the relevant information required for Department review.
