Connecticut General Statute (CGS) Sec. 25-33 requires each water company to annually file with the Department of Public Health (DPH) a written statement containing certain information related to the water system. This information is to be provided in a form prescribed by the Commissioner. In addition, pursuant to Section 19-13-B102(r) of the Regulations of Connecticut State Agencies (RCSA), all community water systems are required to provide a continuously available emergency telephone number to the DPH on or before January 1 of each year. To assist public water systems in complying with these reporting requirements, the Drinking Water Section (DWS) has developed the Public Water System Annual Statement form.
This general application form must be completed & submitted to the Drinking Water Section along with any project or application that requires an approval or permit from the Department.Public Water System General Application For Approval Or Permit | Adobe PDF Version | Microsoft Word Version

Introduction: On June 8, 2001, the Filter Backwash Recycling Rule (FBRR) was published in the Federal Register and on April 22, 2003 the Regulations of Connecticut State Agencies (RCSA) were amended to adopt this rule. 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. Public water systems that are required to comply with the FBRR requirements must ensure that the applicable recycle notification and recordkeeping forms are completed and retained on file for review and evaluation by the Department.
All Community and Non-Transient Non-Community Public Water Systems are required to notify the Drinking Water Section (DWS) of the certified operators designated for each Treatment Plant, Distribution System and Small Water System. The Operator Verification Form is to be submitted by the Public Water System to notify the DWS of any designations or changes. 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.
Every Public Water System is required to submit water quality data to the CT Department of Public Health for compliance purposes. This data is required to be submitted in a format and manner prescribed by the department. All Standard Water Quality Monitoring and Reporting forms are provided by the department to satisfy this requirement. These forms have been listed below and must be used, which will facilitate the submittal of all possible water quality compliance data.

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.
