Sanitary Sewer

What Does Sanitary Sewer Mean?

A sanitary sewer is a piping system that carries waterborne waste from residential, commercial or industrial sites to a waste water treatment plant for processing. Sanitary sewers form an extensive network of underground piping in cities and operate under gravity flow or pressure supplied by pumps.

Many sanitary networks are aging and require the use of trenchless technology to rehabilitate them with minimum disruption to communities.


Trenchlesspedia Explains Sanitary Sewer

Older generation sanitary sewers were made from clay piping, which does not have the longevity of modern concrete and PVC installations. If sewer water escapes from the piping, odors and health risks are created. If excess water seeps into the sewers due to high ground water pressures, the increase in volume flow through the sewer network can overload the downstream wastewater treatment plants.

Trenchless rehabilitation techniques like Cured in Place Lining and pipe bursting give municipalities the ability to maintain sanitary sewers and repair leaks without disrupting services and the quality of life.
