Oso Sewage Lift Station Improvement Project

Document Description: El Toro Water District is proposing to replace the existing Oso Sewage Lift Station and associated equipment with a new lift station in order to improve the station's reliability and serviceability. The existing pump station is outdated and poses significant maintenance costs for ETWD and is nearing the end of its useful life. The new lift station would consist of a new pre-cast wet well with submersible pumps, a valve vault (including a meter), back-up generator, and an outdoor electrical enclosure. Implementation of the project would require the site to be expanded 10 ft to the north. The proposed project would not substantially increase the capacity from the current lift station since the area served by the station has been built out, and no substantial increase in wastewater flow is anticipated.
