Between Bolsa Chica Rd. and Rancho Rd.

The segment of pipeline in this location was replaced using the sliplining method where a 36-inch diameter pipeline was installed into the existing 42-inch diameter pipeline. Several access pits were excavated and high density poly ethylene (HDPE) pipeline segments were fused together and pulled into the old pipeline through these access pits. Over 3,000 feet of pipeline was sliplined.  Backfilling, removal of shoring, testing, and other activities continue.
