Water Valve MaintenanceThe Water Division performs annual valve maintenance involveing a 4-man crew, 2 service trucks, and 2 vacuum trailers. The crewmen acquire a Comprehensive Water Map of the City's Water Distribution System as a result of this maintenance.
This information tells the operator where the water valves are located and the size of each valve. The operators will actually vacuum the debris out of the valve box and then exercise the water valve.
Maintenance ProcedureOne of the most frequently asked questions is why the city performs water valve maintenance. The answer is to insure that the valve is in the open position, that it actually works, and most importantly, that the city can count on it when needed.
This maintenance procedure is one of the most important ones that we perform. The American Water Works Association recommends that water system valves are exercised annually. When the crew finds a water valve that is in need of repair, we schedule it as a priority. The City of Show Low's Water Distribution System has over 2,000 water valves.
