AECOM (legacy Shimmick Construction) is performing the Miramar Water Treatment Plant Clearwell Improvements project, which will add six million gallons of capacity to a facility that serves the water needs for most areas of San Diego north of Interstate 8.

The improvements involve the replacement of Clearwell 1 and 2. The replacements comprise the construction of a new chlorine contact chamber with adjoining lift station; a new operation and maintenance building; a new security guard shack with surveillance equipment and fences; a new pump station electrical building; a pre-fabricated storage building; miscellaneous vaults and structures; and the installation of a one megawatt solar power system.

The project is scheduled for completion in 2020.
