Backflow Laws: Vermont
Vermont Backflow Prevention Laws, Regulations, and Compliance Requirements
Vermont's backflow prevention requirements are administered by the Vermont Department of Environmental Conservation (DEC), Drinking Water and Groundwater Protection Division, which holds EPA primacy. Vermont adopted the 2024 International Plumbing Code for its plumbing standards, supplemented by Vermont Water Supply Rules. Vermont does not administer a statewide backflow tester certification — local jurisdictions and water systems set specific tester requirements, with NEWWA widely accepted across New England. Champlain Water District serves Burlington's region and is Vermont's largest water utility. This guide covers Vermont's regulatory framework and major utility programs.
Vermont State Regulatory Framework
Vermont’s drinking water and cross-connection control requirements are administered by the Vermont Department of Environmental Conservation (DEC), Drinking Water and Groundwater Protection Division, which holds EPA primacy under the federal Safe Drinking Water Act. Vermont’s plumbing code has adopted the 2024 International Plumbing Code (IPC 2024), effective for new construction and renovations in Vermont. Vermont’s plumbing code specifically notes that plumbing shall also conform to the Vermont Water Supply Rules, as adopted by the Vermont Agency of Natural Resources, regarding the prevention of cross-connections.
The Vermont Water Supply Rules establish requirements for public water systems including cross-connection control programs. Vermont IPC 2024, Chapter 6, governs water supply and distribution including backflow prevention device requirements by hazard type. Installation and testing of backflow assemblies shall be in accordance with the ASSE Backflow Prevention Reference Manual or AWWA Backflow Prevention standards.
Vermont Tester Certification — Utility-Administered
Vermont does not administer a statewide backflow tester certification program. Tester certification requirements are set by individual water systems and local plumbing inspection authorities. The New England Water Works Association (NEWWA) provides the dominant training and certification pathway for Vermont testers, consistent with the rest of New England. ABPA and ASSE certifications are also accepted by most Vermont utilities. Confirm your specific utility’s accepted credentials before scheduling testing.
Vermont's 2024 IPC Adoption
Vermont’s 2024 adoption of the International Plumbing Code (IPC 2024) as its plumbing standard represents a recent update to Vermont’s backflow protection framework. The 2024 IPC includes updated cross-connection control requirements and backflow preventer standards. Property owners undertaking new construction or renovations in Vermont should ensure their backflow prevention installations comply with the 2024 IPC as adopted by Vermont, including any Vermont-specific amendments.
Major Water Purveyors in Vermont
Champlain Water District (CWD)
Champlain Water District is Vermont’s largest water utility, serving the Burlington metropolitan area including South Burlington, Williston, Shelburne, and other communities in Chittenden County. CWD wholesale supplies water to many communities that then distribute to their customers. CWD’s cross-connection control program covers commercial and industrial connections in its service territory. Annual testing by utility-accepted certified testers is required.
Burlington Department of Public Works — Water Resources
Burlington’s water system serves Vermont’s largest city and surrounding communities (largely through CWD wholesale supply). Burlington’s cross-connection control program follows Vermont Water Supply Rules requirements.
Green Mountain Water and Environment Association (GMWEA)
GMWEA supports Vermont’s many small water systems with technical assistance including cross-connection control program guidance. Vermont has a large number of community water systems serving small towns and villages — each operating programs at varying levels aligned with Vermont Water Supply Rules.
Vermont Gas Systems and Dual-Fuel Utilities
Vermont’s dual-fuel utility environment (water, gas) means some Vermont properties have complex plumbing systems that require careful cross-connection assessment. Boiler systems for heating — common given Vermont’s cold climate — represent a significant cross-connection control concern requiring appropriate backflow protection.
Vermont Small System Challenge
Vermont has a disproportionately high number of small community water systems relative to its population — many serving villages and rural areas. These small systems often lack dedicated cross-connection control staff and may struggle with program implementation. The Vermont DEC provides oversight through its sanitary survey program. Property owners served by small Vermont water systems should contact their specific water supplier to understand the cross-connection control requirements in their service area.
