Substitute House Bill No. 6977 seeks to enhance the regulatory framework governing the Department of Public Health's (DPH) oversight of drinking water and sewage treatment systems in Connecticut. Key provisions include the repeal of certain subsections and the introduction of new requirements for the renewal of licenses for health-related professions, mandating that individuals renew their licenses annually, biennially, or triennially based on the type of license, with a specific focus on a two-year renewal for those licensed under section 20-278h. The bill also expands the capacity limit for alternative on-site sewage treatment systems from 5,000 gallons per day to 10,000 gallons, with the Commissioner of Public Health responsible for defining system categories and establishing operational requirements.

Additionally, the bill modifies the approval process for public water systems, eliminating the prior requirement for DPH review of certain installations and instead requiring compliance with applicable laws. It emphasizes the need for detailed plans from applicants, including documentation of ownership or control over the sanitary radius. The bill empowers the Commissioner to adopt regulations for the approval process, inspection requirements, and water quality standards, while also allowing for interim policies to be implemented during the regulatory adoption period. Overall, the bill aims to improve public health protections related to drinking water and sewage management, with most provisions set to take effect on July 1, 2025.
