Large Diameter Interceptor Sewer Rehabilitation

Los Angeles, California


The Los Angeles County Sanitation District faced the daunting task of rehabilitating over 10,400 feet of 54- to 78-inch diameter interceptor pipeline serving the Los Coyotes Water Reclamation Plant.


Ranging from 54 to 78 inches in diameter, the interceptor pipeline ran for nearly two miles beneath busy residential and commercial areas. Renewing it without disturbing above ground activities would prove to be a big job.


Using trenchless CIPP technology, SAK installed a strong, long-lasting liner throughout the interceptor’s 10,425-foot length, completing the project on time with minimal disruption to residents and businesses in the service area.
