Project Background

The plant interceptor is the existing pipeline that conveys all of the City’s wastewater to the Water Reclamation Facility (WRF) on McGrath Road for treatment. The pipeline is about 20,000 linear feet of gravity pipe and about 5,000 linear feet of double barrel siphons. The reinforced concrete pipeline was originally installed in the 1980's when the WRF was constructed in its current location.

A condition assessment of the pipeline was initiated in 2013.  Significant deterioration in approximately 70% of the pipeline was identified in the assessment report. The pipeline deterioration is due to age as well as the sulfides, a byproduct of sewage, breaking down the concrete wall.

This project will rehabilitate the worst portions of the plant interceptor by designing and constructing a liner. This solution will provide protection and lessen the deterioration rate for those pipe segments, extending the pipeline’s usable life.
