South Sacramento Recycled Water Project Feasibility Study

Sacramento Regional County Sanitation District

RMC Water and Environment prepared a Title XVI-compliant feasibility study for the South County area near Elk Grove, California. The recycled water project feasibility study examined using up to 50,000 AFY of recycled water for crop and wetlands irrigation with the potential for groundwater recharge of blended recycled water. We estimated recycled water demands and developed conceptual level plans and cost estimates for recycled water conveyance facilities. The feasibility study was prepared to fulfill the requirements of the U.S. Bureau of Reclamation’s Directives and Standards for the Title XVI Water Reclamation and Reuse Program, as part of the grant application.

Design of Studio District Recycled Water Main Extension

Burbank Water and Power

As part of Burbank Water and Power’s (BWP) Recycled Water Master Plan, the Recycled Water Main Extension Project was the first to incorporate the City’s new aggressive recycled water use ordinance. RMC was also selected to design an additional recycled water main extension to connect high profile television and movie studios as well as schools and parks. RMC’s scope of work included a preliminary design report and preparation of plans, specifications and cost estimates for approximately 24,000 LF of 8-inch and 12-inch diameter recycled water pipeline. The design included a crossing of the 134 Freeway and associated Caltrans permitting for open cut construction under a freeway overpass.

Recycled Water Facility

Novato Sanitary District

RMC designed and provided engineering services during construction for a recycled water treatment facility designed to incorporate existing process structures and pipelines that had previously been abandoned. Process components included filter feed and recycled water distribution pumping, yard piping, upflow continuous backwashing filters, chlorine disinfection, clearwell storage, and chemical addition. The $6-million recycling facility provides tertiary treated water for local landscape irrigation, saving Novato an estimated 150 million gallons of water a year, enough to supply about 1,400 single-family homes a year.

Northern San Diego County Regional Recycled Water Project

Olivenhain Municipal Water District

RMC assisted North San Diego County water and wastewater agencies, including the USMC’s Camp Pendleton Base, to study regionalization of existing and planned reclamation systems to further maximize the use of recycled water. The goal of this project was to identify new local and regional recycled water projects that could provide additional recycled water supplies to the local water agencies beyond what they could use individually. RMC developed short-term projects and implementation strategies for regional projects derived from the preferred long-term projects. We also analyzed the recycled water facilities, both treatment and distribution, and conducted a comprehensive evaluation of each agency’s ability to interconnect.

Recycled Water Customer Support

West Basin Municipal Water District

RMC is helping the West Basin Municipal Water District to market its recycled water and to retrofit customers as part of the Carson expansion project serving the ARCO refinery. RMC also worked with the customers in the Palos Verdes area to assist the District in determining the feasibility of expanding the system in that area. Services being provided to the District on these projects include assessing the feasibility of recycled water service, obtaining agreements with potential customers, responsibility for regulatory approvals, and bid and construction assistance with recycled water conversions from portable to reclaimed water.

Water Purification Demonstration Project

City of San Diego

RMC was retained by the City of San Diego to provide program management and public outreach services for the Water Purification Demonstration Project. The main goal of the Demonstration Project is to explore the feasibility of the project’s treatment technology to produce water that can be sent to a reservoir and later distributed as drinking water. In September 2012 the California Department of Public Health’s approved the project concept. San Diego’s proposed project for surface water augmentation using advance treated recycled water is the first planned project of its type in California. The Demonstration Project is intended to provide the technical, water quality, environmental, public outreach, regulatory and funding requirements necessary to implement a full-scale project.

Recycled Water Master Plan

City of Los Angeles

RMC lead the Los Angeles’ Recycled Water Master Plan, one of the most cutting edge and comprehensive recycled water planning efforts in the country. Our team:

• Conducted five separate planning efforts in the areas of: indirect potable reuse, non-potable reuse, satellite treatment, system reliability, and long-term recycling vision
• Envisioned rapidly expanding on L.A.’s recycled water systems through indirect potable reuse via groundwater recharge
• Investigated possibilities for expanding recycled water use to significantly reduce the need for imported water in the future
