Water Main

Definition - What does Water Main mean?

A water main is a primary underground pipe in a municipal water distribution system. It is a major artery that supplies water to smaller pipes on the way to homes and businesses. Water mains take clean water from a city’s water treatment plant to communities that need it, and it is a critical piece of a nation’s utility infrastructure.

Trenchless techniques have been very successful in the rehabilitation of older water main pipes.

Trenchlesspedia explains Water Main

Water mains can be subject to various wearing issues including tuberculation, faulty joints, inadequate hydraulic capacity and corrosion. Pipe rehabilitation often involves the sliplining of HDPE pipes rather than replacement, and water main renewal costs the U.S. over $1 billion per year. Trenchless technology seems to be the best way to prevent and repair broken water mains.

Water mains have been flagged as critical issues in aging utility infrastructures in developed countries. The pipes generally move a high volume of water under pressure to neighborhoods that are depending on water mains to bring them clean water from the city's water treatment facility.

Trenchless technology has been effectively applied to the rehabilitation of water main pipes by use of cured-in-place pipes, sliplining, robotic pipe repair and more.
