Design-Build Water Group Job 926 – San Diego, CA


This design-build project involved the replacement orrepair of 2.47 miles of water mains in the Point Loma area of San Diego. The new mains were between 6” and 12” and included new fire hydrants, air vacs, blow offs, and water services. Orion designed and installed temporary water supplies to keep all fire suppression in the business district in service and all residences with running water. Orion, with its design partner, worked with the City of San Diego to utilize trenchless rehabilitation for portions of the water main repairs which allowed the water services to be back in service much faster than traditional open-cut methods.
