The Morena Northern Pipelines and Tunnels, North City Water Reclamation Plant (NCWRP) Expansion, the NCWRP Flow Equalization Basin and North City Pure Water Facility (NCPWF) and Pump Station projects will be built in the University City community.
The Northern Alignment will divert 32 million gallons per day (mgd) of wastewater that would otherwise be treated and discharged into the ocean to the North City Water Reclamation Plant, where it will be treated to recycled water standards.
The NCWRP is being expanded to continue providing recycled water to its current users as well as supplying the NCPWF with the water necessary for advanced purification. The NCPWF will use a proven five-step treatment process to further clean 30 mgd of recycled water to produce purified water. The pump station will convey the purified water to the Miramar Reservoir where it will be stored before receiving additional treatment at the Miramar Drinking Water Plant.
Morena Northern Pipelines and Tunnels
Project Started:June 2021Expected Completion:2024
The Morena Northern Pipelines and Tunnels will connect to the Morena Pipelines Middle Alignment to the south and the North City Water Reclamation Plant to the north. This project begins on Genesee Avenue between Appleton Street and state Route 52 and continues on Genesee Avenue, Nobel Drive, Towne Centre Drive and Executive Drive. Tunneling will be completed at Genesee Avenue and SR-52, at Genesee Avenue and Rose Canyon, and under Interstate 805.
The North City Water Reclamation Plant (NCWRP) Expansion will increase the plant's recycled water production from 30 mgd to 52 mgd. The expansion requires larger equipment and infrastructure. The expansion will occur on the existing NCWRP site.
As part of the North City Water Reclamation Plant (NCWRP) expansion, a new Flow Equalization Basin will be constructed to expand the capacity of the primary effluent storage. The Flow Equalization Basin will regulate peak wastewater flow rates so that water can be delivered at more manageable flow rates to the Metropolitan Biosolids Center for further treatment.
The North City Pure Water Facility (NCPWF) will use a proven five-step process to treat recycled water to purified water standards. Upon completion, the facility will produce 30 mgd of purified water, which will be conveyed by the Pump Station to the Miramar Reservoir for storage. The NCPWF and Pump Station will be built on Eastgate Mall across from the NCWRP.
The Metropolitan Biosolids Center (MBC) is the City's regional biosolids facility that receives and processes solids from both the North City Water Reclamation Plant (NCWRP) and the Point Loma Wastewater Treatment Plant. The NCWRP will undergo an expansion under Phase 1 of the Pure Water Program, increasing biosolids flows and loadings to MBC. To accommodate these increased loadings, upgrades and improvements at MBC will be necessary.
