Lift Station 80-03 Upgrade Project

Lift Station 80-03 Upgrade Project

The Coachella Valley Water District’s (CVWD) Lift Station 80-03 project (Project) will consist of improvements to the existing Lift Station 80-03 site. The existing lift station layout is set up as a dry well/wet well. Most of the piping and valves within the dry well were installed when the lift station was built in 1974 while more recent electrical upgrades completed in 2004. To improve operational reliability all inlet and discharge piping, pumps, valves, electrical equipment, and VFDs will be replaced. New upgrades for the Lift Station will be as follows: • A new wet well (16-feet diameter by 45.2-feet in depth) will be installed. The current dry and wet wells will be retrofitted/reinforced and used as emergency storage facilities. • The addition of a fourth pumping unit provides an ultimate pumping capacity of 10,400 gallons per minute (gpm) with 3 duty and 1 standby pumping units. The Project will increase overall storage capacity; however, it will decrease overall pumping capacity (original pumping capacity was over engineered and more than needed). Current pumping capacity is 12,000+ gmp. New pumping capacity is 10,400 gpm (8,400 gpm with pumps and 2,000 gpm with backup diesel generator) • The removal and replacement of an emergency diesel generator. The new replacement 2,000 gpm emergency diesel generator will provide an ultimate pumping capacity of 10,400 gpm. • The existing driveway and arm-gate will be redesigned to accommodate for future CV Link projects and address vehicle view-of-sight safety factors. The current driveway and arm-gate locations make it difficult for CVWD personnel to safely exit Cook St. • Remove all existing woodchip odor control components, including wood chip containment area (3,550 sq ft), piping, fans, and support facilities, and replace with a new Packaged Odor Control System consisting of a two (2) stage biological/ carbon all-in-one system. • Install a new concrete pad(s) to house the new odor control biomedia/carbon unit(s), sized for 850 cfm. • Replace the electrical building with a new updated Battery Cell Management Unit (CMU) Electrical Building. The Project will also include site improvements to upgraded site piping, paved access driveways, perimeter fencing, and lighting. Excavation of 26 feet will be needed to install new 24-inch gravity sewer lines on the property. The upgrades to the existing Lift Station 80-03 facility are anticipated to begin in or around April 2026 and last approximately 455 calendar days. The surrounding land uses consist of residential, open space, and roadways. The existing lift station will continue to convey wastewater while the upgrades are under construction, causing no disruptions in services. The Project is not located within or adjacent to a conservation area associated with the Coachella Valley Multiple Species Habitat Conservation Plan (CVMSHCP). The sites are not subject to the CVMSHCP development mitigation fee because they are previously developed.
