City of Los Angeles
GeoSpray® 49" Brick Sewer

Project Overview
Los Angeles Sanitation collects, cleans and recycles solid and liquid waste generated by residential, commercial and industrial users in the city of Los Angeles and surrounding communities. The system serves over four million residents. The Bureau of Engineering for the Department of Public Works is responsible for maintaining the sewer and storm water systems owned by the city. Over the last several decades, the city has worked to rehabilitate and replace much of its aging sanitary sewer system. As the progress continues, the city is now doing more work on the larger diameter piping structures in its system. These larger diameter rehabilitations are significantly more costly than the smaller diameter repairs and many of the systems employed by the city are significantly budget constrained.

In order to test and develop alternative rehabilitation systems for these large diameter sewer structures, the city approved a pilot project with GeoSpray geopolymer mortar in 2016.
