RMC’s leaders bring hands-on experience in water quality, regulatory requirements, system operations, and facility planning and design. And, we are adept at construction sequencing and completing facility upgrade projects while keeping existing facilities operational.

Regional Water Filtration Facility Program

Yucaipa Valley Water District

Serving as program manager, RMC managed the master plan, design and construction of a new 12-mgd regional water treatment facility. Designed for expansion up to 36 mgd, the facility treats water from the State Water Project and helps meet increased demand while reducing overdraft of local groundwater supplies. For the program, RMC has:

• Managed facility design which uses microfiltration technology with nanofiltration equipment for TOC removal
• Provided regulatory assistance, include completing DPH permitting
• Completed bid documents for a booster pump station to transfer water from the new WFF to two different pressure zones

 

Manning Water Treatment Plant

Irvine Ranch Water District

RMC provided preliminary evaluation and design of a 300-gpm facility with 500-gpm future capacity, including evaluation of treatment processes to meet the drinking water regulations for treatment of groundwater under the direct influence of surface water. RMC:

• Identified and evaluated three alternative treatment technologies including direct pressure filtration, membrane filtration, and two-stage filtration
• Prepared a draft Operations Plan to meet DHS requirements
• Designed plant upgrades, including conversion of treatment process from chlorination to chloramination and onsite sodium hypochlorite system to a bulk hypochlorite dosing system
• Updated CEQA compliance documentation

 

Banner Cascade Pipeline Project

Nevada Irrigation District

As part of a consultant team, RMC designed 5.5 miles of high pressure pipeline for raw water transmission, three control facilities, encasement of an existing canal, and rehabilitation of an existing siphon. RMC’s design:

• Accommodated a narrow construction corridor with limited contractor access
• Addressed close proximity of large trees, rocks, and utilities to the alignment
• Was accomplished using designated “reach experts” who worked with stakeholders and permitting agencies to define a feasible alignment and reasonable cost of construction
• Was optimized to improve operations and reduce costs

 

Water Meter Program Management

City of Lodi

RMC is managing Lodi, California’s four-year $34-million water meter program, which:

• Is an important component of the city’s overall strategy to effectively manage its water supplies and meet its long-term water supply needs
• Will install new residential water meters at 13,000 residences and about 21 miles of new water main
• Is on a tight timetable and involves coordination between multiple people in the city, the subcontractors, and residents

Freeport Regional Water Project

Freeport Regional Water Authority

RMC is part of the program management team for a $900-million regional water supply program providing up to 85 mgd of surface water to be used in conjunction with groundwater to help meet future water supply needs in central Sacramento County and the San Francisco East Bay. RMC:

• Analyzed intake pump station sites and contributed to design of the pump station on the Sacramento River
• Participated in plan and specification reviews for Segment 1 and Segment 3 pipeline projects
• Completed environmental documentation and permitting, regulatory agency coordination, and mitigation monitoring
• Managed construction of 5.1 miles of 84-inch and 3.9 miles of 72-inch steel pipe

Cedar Glen Water Treatment Plant and Emerald Bay Pump Station

Lake Arrowhead Community Services District

RMC was responsible for the design and construction management services of a new 2.0-mgd water treatment plant in Lake Arrowhead to replace an existing facility that was no longer able to comply with drinking water regulations. RMC:

• Designed the treatment plant’s pre-ozonation, adsorption clarifier, mixed media filtration, chemical feed, wash water recovery, post chlorination, finished water pumping and operational storage facilities
• Evaluated alternatives for final disinfection
• Designed and managed construction for the Emerald Bay raw water intake pump station as well as raw water conveyance pipeline to the Cedar Glen Water Treatment Plant

CIP Upgrades for Pipelines, Pump Station and Tank

Elsinore Water District

RMC prepared a Capital Improvement Plan in 2005 that identified and prioritized projects to maintain and expand the District facilities. We then provided conceptual design, final bid documents and bid services, and construction administration for various projects such as:

• 4000 feet of 8-inch piping in Sunnyslope Avenue
• Junkle Booster Pump Station
• Pump replacement at Lash Pump station
• 2500 feet of pipeline from Wisconsin Avenue to Lash Pump Station
• Piping modifications and coating for two storage tanks
