The current sewer flows entering the lift station will be permanently diverted at the influent manhole (MH) to the downstream gravity sewer connected to EMWD's gravity collection system. An equal amount of flow (50,000 gallons per day current to 270,000 gpd buildout) will be diverted from EMWD's gravity sewer to the Santa Rosa Water Reclamation Facility at the Adams Avenue Diversion structure. LEE + RO’s role is to review, evaluate, and validate RCWD’s developed and selected concepts for flow control modifications and flow diversions. LEE + RO will make recommendations supporting the flow control concepts, develop flow calculations, preliminary layout, sizing, and configuration of the recommended flow control facilities. LEE + RO’s design services are for a bid-ready set of contract documents. The documents will include plans, specifications, and cost estimates for the Winchester lift station Influent MH Modifications and the Adams Avenue Diversion Structure Modifications. ###### Topics: [2021](https://www.lee-ro.com/news/topic/2021) [Condition Assessment](https://www.lee-ro.com/news/topic/condition-assessment) [Electrical](https://www.lee-ro.com/news/topic/electrical) [Instrumentation and Control](https://www.lee-ro.com/news/topic/instrumentation-and-control) [Lift Station Wastewater](https://www.lee-ro.com/news/topic/lift-station-wastewater) ![Kevin Saleh, PE](https://via.placeholder.com/100x100.jpg/e0e7ee) #### Written by [Kevin Saleh, PE](https://www.lee-ro.com/news/author/kevin-saleh) ###### [Previous Post](https://www.lee-ro.com/news/lee-ro-recognized-by-asce-and-apwa-with-awards) [![](https://via.placeholder.com/300x150.jpg/e0e7ee)](https://www.lee-ro.com/news/lee-ro-recognized-by-asce-and-apwa-with-awards) ###### [LEE + RO recognized by ASCE and APWA with Awards](https://www.lee-ro.com/news/lee-ro-recognized-by-asce-and-apwa-with-awards) ###### [Next Post](https://www.lee-ro.com/news/city-of-colton-design-wastewater-treatment-plant-upgrades-and-expansion) [![](https://via.placeholder.com/300x150.jpg/e0e7ee)](https://www.lee-ro.com/news/city-of-colton-design-wastewater-treatment-plant-upgrades-and-expansion) ###### [LEE + RO To Design the Upgrades and Expansion of the City of Colton’s Wastewater Treatment Plant](https://www.lee-ro.com/news/city-of-colton-design-wastewater-treatment-plant-upgrades-and-expansion) [All posts](https://www.lee-ro.com/news/all) ### Related News ### News by Tag - [2021 (25)](https://www.lee-ro.com/news/tag/2021) - [2022 (9)](https://www.lee-ro.com/news/tag/2022) - [2023 (25)](https://www.lee-ro.com/news/tag/2023) - [2024 (8)](https://www.lee-ro.com/news/tag/2024) - [Advanced Water Treatment (1)](https://www.lee-ro.com/news/tag/advanced-water-treatment) - [Civil (7)](https://www.lee-ro.com/news/tag/civil) - [Condition Assessment (13)](https://www.lee-ro.com/news/tag/condition-assessment) - [Construction Management (4)](https://www.lee-ro.com/news/tag/construction-management) - [Disinfection/Chemical Handling, Storage, Feeding (7)](https://www.lee-ro.com/news/tag/disinfection-chemical-handling-storage-feeding) - [Electrical (31)](https://www.lee-ro.com/news/tag/electrical) - [Employees (9)](https://www.lee-ro.com/news/tag/employees) - [Flow/Pressure Control Facility (3)](https://www.lee-ro.com/news/tag/flow-pressure-control-facility) - [Inspection Services (2)](https://www.lee-ro.com/news/tag/inspection-services) - [Instrumentation and Control (18)](https://www.lee-ro.com/news/tag/instrumentation-and-control) - [Lift Station (2)](https://www.lee-ro.com/news/tag/lift-station) - [Lift Station Wastewater (4)](https://www.lee-ro.com/news/tag/lift-station-wastewater) - [Mechanical (7)](https://www.lee-ro.com/news/tag/mechanical) - [Membrane (MBR/RO) (1)](https://www.lee-ro.com/news/tag/membrane-mbr-ro) - [Pipeline (1)](https://www.lee-ro.com/news/tag/pipeline) - [Pipeline Collections (5)](https://www.lee-ro.com/news/tag/pipeline-collections) - [Pipeline Force Mains (4)](https://www.lee-ro.com/news/tag/pipeline-force-mains) - [Pipeline Recycled Water (1)](https://www.lee-ro.com/news/tag/pipeline-recycled-water) - [Pipeline Water (3)](https://www.lee-ro.com/news/tag/pipeline-water) - [Power Distribution (6)](https://www.lee-ro.com/news/tag/power-distribution) - [Pump Station (4)](https://www.lee-ro.com/news/tag/pump-station) - [Pump Station Water (4)](https://www.lee-ro.com/news/tag/pump-station-water) - [Recycled Water (6)](https://www.lee-ro.com/news/tag/recycled-water) - [Recycled Water Storage (1)](https://www.lee-ro.com/news/tag/recycled-water-storage) - [Storm Water (1)](https://www.lee-ro.com/news/tag/storm-water) - [Structural (12)](https://www.lee-ro.com/news/tag/structural) - [Tanks/Reservoirs Water (3)](https://www.lee-ro.com/news/tag/tanks-reservoirs-water) - [Wastewater Conveyance (6)](https://www.lee-ro.com/news/tag/wastewater-conveyance) - [Wastewater Treatment (6)](https://www.lee-ro.com/news/tag/wastewater-treatment) - [Wastewater Treatment Facilities (3)](https://www.lee-ro.com/news/tag/wastewater-treatment-facilities) - [Water Conveyance (9)](https://www.lee-ro.com/news/tag/water-conveyance) - [Water Storage (1)](https://www.lee-ro.com/news/tag/water-storage) - [Water Treatment (2)](https://www.lee-ro.com/news/tag/water-treatment) - [Water Treatment Facilities (3)](https://www.lee-ro.com/news/tag/water-treatment-facilities) - [Water Well/Wellhead Facility (1)](https://www.lee-ro.com/news/tag/water-well-wellhead-facility) **Los Angeles (HQ)** [626-912-3391](tel:6269123391) **Bay Area** [925-937-4050](tel:9259374050) **San Diego** [858-558-4411](tel:8585584411) - [Privacy Policy](https://www.lee-ro.com/privacy-policy) © 2000 - 2025 LEE & RO, Inc.
