Sewer Systems: Construction Considerations

Pressure sewers (effluent or grinder) and gravity sewers require different methods of construction, different installation techniques, and different degrees of accessibility to install the various products and system components. The construction impact of installing any sewer system technology falls under two main categories: on-lot and right-of-way (ROW). 

Due to the use of small-diameter mainlines that follow the contour of the land, the typical ROW construction impact of pressure sewers is considerably less than that of gravity sewers. The on-lot construction impact of effluent sewers is similar to grinder sewers, but effluent sewers provide primary treatment, lower life-cycle costs,i and 24-hour reserve capacity. 

Effluent sewer systems have been installed all over the country and around the world – in sparsely populated rural areas, dense downtown commercial areas, and neighborhoods with small lots, mature landscaping, and underground utilities. As a result of its low construction impact and overall affordability, this efficient technology is an ideal solution for a wide range of applications. 

This document will explain various aspects of effluent sewer construction and how they compare to grinder and gravity sewer requirements in areas with small lots and existing streets, homes, and businesses.
