BACKGROUND
The Santa Ana Trunk Sewer carries sewage from the southern portion of the cities of Santa Ana and Costa Mesa to the Orange County Sanitation District (OC San) Plant No. 1. This sewer was originally constructed in the early 1950s and consists of unlined 42-inch, and 48-inch diameter reinforced concrete pipe. Over the past 70 years, several projects have replaced or rehabilitated small portions of the sewer and rehabilitated most of the manholes.
The existing Santa Ana Trunk Sewer is located in permanent easements and public right-of-way. The Segerstrom properties comprise a business park with multiple office, commercial, and industrial buildings. OC San has negotiated temporary construction easements for a duration of 36 months and parking spaces for a duration of 9 months with Segerstrom to perform the construction activities.
Construction activities within the subject properties include the construction of a new 84-inch diameter manhole, rehabilitation of two existing manholes, installation of approximately 1,840 linear feet of 48-inch diameter cured-in-place pipe (CIPP), routing of approximately 3,500 linear feet of temporary bypass piping, and operation of temporary bypass pumping equipment.
