The infrastructure engineered to treat, pump and distribute potable water to a city or district. This includes everything from the raw water intake and filtration plants to the high-pressure transmission mains and local distribution grids. Pipefitters and utility plumbers working in this sector deal with massive pipe diameters, high-pressure valves, and strict municipal codes.
The city waterworks department is shutting down the main on Fifth Street for a valve replacement tonight.
Working in waterworks requires different certifications than standard residential plumbing, especially regarding cross-connection control and heavy equipment operation.
