Jefferson Street around the Buena Vista Lagoon has reopened to regular traffic following an eight-month closure to allow for the installation of two new 4,200-feet-long sewer pipes.
The pipeline broke in 2007 causing a sewage spill. Although crews repaired the pipe, an evaluation of the pipe’s condition found that it needed to be replaced. The section of pipeline that failed in 2007 was abandoned in place and replaced with two parallel 24-inch pipes constructed within the roadway.
One pipe will be used as a sewer force main, which uses pressure to move the water and sewage. The other will be used when rain causes excess flows and as a backup sewer main, further protecting the Buena Vista Lagoon.
The pipeline is part of the Vista/Carlsbad interceptor sewer system, which carries wastewater from Vista and Carlsbad to the Encina Water Pollution Control Facility on Avenida Encinas in Carlsbad. The system is jointly owned by the cities of Carlsbad and Vista.
Carlsbad and Vista shared the project’s $4.4 million cost, based on their portions of the pipe’s ownership, with Vista paying 90 percent and Carlsbad the remainder.
