Valve Exercising at Public Community Drinking Water Systems

Waterline distribution valves are rarely used, and the need for operation (opening and closing) often comes at times of critical usage: emergency shutdown, ventilation, pressure relief of flood risk, etc. In an emergency, sections of a water distribution system may need to be completely shut down without delay. It’s not uncommon for valves to rest idle for many years, even decades between operation. If a valve is not used or properly exercised, it can seize-up from corrosion and make the valve inoperable. Valve exercising programs can help maintain the useful life, safety, and operation of water system valves. Vermont’s Department of Environmental Conservation (DEC) seeks proposals for a contractor(s) to perform Public Water System Valve: locating, inspecting and exercising, and documenting specific operating information and the GPS data of valves in a format suitable and compatible with the Water System.
