--- title: Recycled description: With an intimate understanding of the complexities of water reclamation and technologies that raise the bar for potable and non-potable reuse, LEE + RO is helping to bring water security to California’s communities. We’re developing safer, more efficient and effective ways to take the water out of wastewater. --- - [News](https://www.lee-ro.com/news) - [Archive](https://www.lee-ro.com/news/archive) - [Clients](https://www.lee-ro.com/clients) - [Memoriam](https://www.lee-ro.com/memoriam) - [COVID-19](https://www.lee-ro.com/covid-statement) [![LEE RO Logo color NEW 150](https://www.lee-ro.com/hs-fs/hubfs/LR%20Global%20Header/LEE%20RO%20Logo%20color%20NEW%20150.png?width=406&height=158&name=LEE%20RO%20Logo%20color%20NEW%20150.png) ![LEE RO Logo color NEW 150](https://www.lee-ro.com/hs-fs/hubfs/LR%20Global%20Header/LEE%20RO%20Logo%20color%20NEW%20150.png?width=406&height=158&name=LEE%20RO%20Logo%20color%20NEW%20150.png)](https://www.lee-ro.com/lr-homepage?hsLang=en) - Careers - [Why LEE + RO](https://www.lee-ro.com/careers/why-lee-ro) - [Openings](https://www.lee-ro.com/openings) - What We Do - [Wastewater Treatment](https://www.lee-ro.com/services/wastewater-treatment) - [Wastewater Conveyance](https://www.lee-ro.com/services-wastewater-conveyance) - [Water Treatment](https://www.lee-ro.com/services-water-treatment) - [Water Conveyance](https://www.lee-ro.com/services-water-conveyance) - [Design-Build](https://www.lee-ro.com/services/design-build) - [Recycled Water](https://www.lee-ro.com/services-recycled-water) - [Electrical and I&C](https://www.lee-ro.com/services-electrical) - [Condition Assessment](https://www.lee-ro.com/services-condition-assessment) - [Construction Management](https://www.lee-ro.com/services-construction-management) - [Solutions](https://www.lee-ro.com/solutions) - [Projects](https://www.lee-ro.com/projects) - Who we are - [Vision + Mission + Values](https://www.lee-ro.com/about/vision-mission-values) - [Founders](https://www.lee-ro.com/about/the-founders) - [Our Story](https://www.lee-ro.com/about/our-story) - [Leadership](https://www.lee-ro.com/about/leadership) - [Sustainability](https://www.lee-ro.com/about/sustainability) - [News Archive](https://www.lee-ro.com/news/archive) - [Contact](https://www.lee-ro.com/contact) - #### WHAT WE DO - [Wastewater Treatment](https://www.lee-ro.com/services-wastewater-treatment) - [Wastewater Conveyance](https://www.lee-ro.com/services-wastewater-conveyance) - [Water Treatment](https://www.lee-ro.com/services-water-treatment) - [Water Conveyance](https://www.lee-ro.com/services-water-conveyance) - [Recycled Water](https://www.lee-ro.com/services-recycled-water) - [Electrical](https://www.lee-ro.com/services-electrical) - [Condition Assessment](https://www.lee-ro.com/services-condition-assessment) - [Construction Management](https://www.lee-ro.com/services-construction-management) ### RECYCLED WATER: # More of what we’re made of. Each of us is at least 60% water, and there are more of us every day. Yet our water supplies have not increased. Nowhere is this more apparent than in drought-plagued California, where half the nation’s fruits and vegetables are grown. But out of the deepest need, the most innovative ideas emerge. From potable and non-potable reuse to aquifer recharge, we’re working to help communities turn scarcity into sustainable, standard-raising solutions, for a more resilient, renewable supply of the stuff that makes us human. **Our Recycled Water expertise includes:**   - Ultrapure Recycled Water Treatment - Title 22 Recycled Water Treatment - Chemical Treatment - UV and Chemical Disinfection - Groundwater Reinjection - Storage Reservoirs - Pump Stations - Transmission and Distribution Mains - Medium and Low Voltage Power Distribution - Instrumentation & Control System Design ###### CITY OF Spring Valley **30-Inch Diameter, 6-Mile Long, Recycled Water Transmission Main, Otay Water District** LEE + RO was responsible for the alignment study, surveying, geotechnical evaluation, environmental and permitting services, right-of-way acquisition, preliminary design, final design and construction support services for a $17 million, 6-mile long, 30-inch diameter recycled water pipeline connecting the City of San Diego’s South Bay Water Reclamation Plant to the District’s 450-1 Recycled Water Reservoir. The construction employed a wide variety of techniques including horizontal directional drilling (HDD) to cross Interstate 805, Otay River, and State Route 905.  This project was awarded ***“Water Reuse Project of the Year,” “ASCE Outstanding Project of the Year” and “CMAA Project Achievement Award.”*** ![Spring](https://cdn2.hubspot.net/hubfs/5816394/CLEAN-images/gfx/lazy-placeholder-350x200.jpg) ###### CITY OF Irvine **San Joaquin Reservoir Flow Control Facility, Irvine Ranch Water District** LEE + RO provided planning, design and construction support services for a $3 million, flow control and pumping facilities project.  This project consisted of an 8,250 gpm pumping station (with three 75 hp, 4,125-gpm, VFD-driven pumps), a flow control facility, hypochlorite disinfection facility, and sub-surface water collection and pumping facility at the base of the reservoir dam.  The District purchased the reservoir from the Metropolitan Water District and converted it into a reclaimed water storage reservoir, integrating it into their Zone B recycled water system. ![Irvine Recycled](https://cdn2.hubspot.net/hubfs/5816394/CLEAN-images/gfx/lazy-placeholder-350x200.jpg) ###### CITY OF Walnut **Parker Canyon Recycled Water Reservoir and Bourdet Pumping Station Improvements, Walnut Valley Water District** LEE + RO provided engineering, design, and construction support services for a $4.5 million project consisting of a new 1.3 MG capacity recycled water reservoir, the addition of a new 750 gpm capacity vertical turbine pump as well as adding two stages to each of the two existing vertical turbine pumps at the Bourdet Booster Pump Station. A cast-in-place, two-celled concrete reservoir was ultimately designed after  circular Type I + III pre-stressed concrete,  rectangular concrete, and steel reservoirs were analyzed.  Other improvements consisted of extensive grading, retaining walls, access roads and landscaping, electrical, controls and SCADA system improvements.  ![Walnut Recycled](https://cdn2.hubspot.net/hubfs/5816394/CLEAN-images/gfx/lazy-placeholder-350x200.jpg) ###### CITY OF Irvine **Turtle Rock Zone B+ Recycled Water and Zone 6A Potable Water Pump Stations Upgrading, Irvine Ranch Water District** LEE + RO provided the analysis, design, and construction management services for $2.5 million in upgrades to the Zone B+ Recycled Water and Zone 6A Potable Water Pump Stations. The Zone B+ Recycled Water Pump Station improvements included new VFDs and flow/pressure regulators. The Zone B+ Recycled Water station has 7 vertical turbine pumps discharging into two different headers, which ultimately combine into one main header. The first header receives flow from 3 constant-speed pumps, each rated at 1,330 gpm at 320 feet of TDH. The second header receives flow from 4 pumps, all rated at 320 feet TDH and driven through VFDs: two 100 hp/1,000 gpm pumps; one 75 hp/500 gpm pump; and one 50 hp/250 gpm pump. The pump lineup was not properly installed and the system was not operating reliably. LEE + RO performed hydraulic and surge analysis and optimized the system by converting an existing pressure reducing station from back-up Zone B to a primary Zone D operation. Zone 6A Potable Water Pump Station capacity was increased to 2,500 gpm and new VFDs and SCADA were added. ![RW Irvine New](https://cdn2.hubspot.net/hubfs/5816394/CLEAN-images/gfx/lazy-placeholder-350x200.jpg) **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.
