The Water Authority is building a new flow regulatory structure to upgrade the untreated water system in the northwest area of Mission Trails Regional Park. When complete, the project will upgrade the untreated water system that delivers water to treatment plants that serve the central and southern areas of San Diego County.
Construction is taking place Monday through Friday between 7 a.m. and 7 p.m. and will close some trails in the western portion of the park. Trail closure signs, including a park map showing alternate trails are posted to help park users navigate the trails.
The project currently underway will construct a new 5-million-gallon underground covered reservoir, a flow control facility and pipeline interconnections. The reservoir will be covered with soil and vegetation, except for several access hatches and vents that allow for air movement inside the reservoir.
This work is part of a suite of projects called the Mission Trails Project located in the western portion of the park.
