Upcoming Work

Construction moves forward on the Bay Bridge Pump Station and Force Mains Replacement Project, an important effort to upgrade and modernize the regional sewer system serving Newport Beach.

Here’s what you need to know about upcoming work:

  • What:  Crews will be digging about 50 feet underground to create access points for new sewer force main pipelines. A soil improvement process will be used to safely support this excavation.
  • Locations:
    1. Next to OC San’s pump station at 250 E. Coast Highway
    2. Near the southeast corner of Coast Highway and Dover Drive
  • When:  Mid-September and will last about 3 months*
  • Hours:  Monday to Friday, 7 a.m.–5 p.m.

*All dates and times are subject to change due to operational factors or inclement weather.

Project Description

This project will replace the existing Bay Bridge Pump Station located on Coast Highway between the Bay Bridge (east of Dover Drive) and Bayside Drive in the City of Newport Beach. The project will also replace the pressurized pipes, also referred to as force mains, consisting of two parallel pipelines which carry wastewater across the lower Newport Bay Channel. Wastewater then makes it way to OC San’s Reclamation Plant No. 2 in Huntington Beach.

Project Background

The Bay Bridge Pump Station was originally constructed in 1966 and is over 50 years old. The force mains are also over 50 years old. These critical assets are reaching the end of their useful life and need to be replaced to ensure they are reliable for the next 50 years. The new facility will be built to current structural and safety codes, making it safe and reliable to workers and the public.

The Bay Bridge Pump Station and Force Mains are located near pristine beaches along the Newport Channel Bay and is surrounded by residents, businesses, and visitors throughout the world. This pump station system transports between 4 to 18 million gallons of wastewater every day from the Newport Beach community. This project is needed to ensure we continue to collect, transport, and recycle Newport Beach’s wastewater safely while protecting the public health and the environment.

More information about the project can be found in the FAQ section.
