BACKGROUND
The Bay Bridge Pump Station and associated force mains were constructed in 1966 on East Coast Highway just east of the Lower Newport Bay Channel. The pump station and force mains are critical to the Orange County Sanitation District's (OC San) infrastructure as it conveys over half of Newport Beach's wastewater. The pump station is almost 60 years old and at the end of its useful life. The existing force mains were previously lined, are at the end of their useful life, and need to be replaced with a larger size to improve reliability. The force mains will be constructed under the Lower Newport Bay Channel via microtunneling. It is imperative that the facility and force mains be upgraded to ensure continuous service.
RELEVANT STANDARDS
* Comply with California Public Contract Code Section 20103.8, award construction contract to lowest responsive, responsible bidder
