Trenchless Technology Applied to Degraded Gravity Concrete Outfall Sewer to Avoid Collapse
This paper discusses the application of trenchless technology for replacement of a 1500 foot section of failing concrete gravity sewer, which serves as an outfall interceptor for Kern Sanitation Authority's Wastewater Treatment Plant. Video camera inspection indicated that it was not feasible to rehabilitate the existing gravity sewer which passes beneath a major railroad, highway, irrigation canal and 4 lane overpass structure. Therefore, alternative technology was incorporated using bored and jacked steel casings and PVC carrier pipe to replace the concrete pipe. The existing pipe was then abandoned and filled from the inside to avoid collapse. The project was designed and administered by Kern County Waste Management and was successfully completed for about $805,000 total construction cost, approximately $535 per linear feet of sewer pipe.
