Based in Walnut Creek, California, RMC Water and Environment works on large-scale water recycling projects in California. Dedicated to continued innovation, RMC Water and Environment is a member of the California Water Environment Association (CWEA). On its website, the CWEA provides information about California’s State Water Resources Control Board’s (SWRCB) General Waste Discharge Requirement (WDR).

Adopted in May 2006, the WDR offers a statewide approach focused on reducing Sanitary Sewer Overflows (SSOs) and applies to all of California’s publicly-owned sanitary sewer collection systems that maintain over one mile of sewerage pipes.

The WDR requires relevant organizations take all possible steps to prevent untreated wastewater from entering creeks, storm drains, and natural bodies of water in the event of an SSO. All SSOs are reported to the SWRCB using its online reporting system, with the Office of Emergency Services requiring notification when spills exceed 1,000 gallons.

All of California’s publicly-owned collection system agencies that operate over one mile of sewerage pipe are also required to create Sewer System Management Plans (SSMPs). The SSMP should be available to the public and must meet the WDR’s mandatory requirements to demonstrate a practical commitment to health and safety.


EBMUD Project to Replace Aging Reservoir in Lafayette, California

Recognized as one of the Top 500 Design Firms in its field in 2016, RMC Water and Environment consults with cities and counties across California to provide complex management spanning wastewater treatment facilities and sewer systems. One of RMC Water and Environment’s recently initiated projects involves working with the East Bay Municipal Utility District (EBMUD) to replace the aging Leland Reservoir.

Situated in Lafayette, California, the open-cut 14.5-acre reservoir site was constructed in 1955 and has been characterized by EBMUD as approaching the final stages of its service life. The replacement project involves setting in place a pair of seismically sound 8-million-gallon concrete tanks and rebuilding and realigning access roads.

Another aspect of the project, which is expected to last from 2021 to 2023, involves setting in place a water pipeline 36 inches in diameter. Spanning 2,700 feet, this pipeline will be installed under residential streets in the vicinity and link to nearly 1,000 feet of new pipeline on the reservoir property itself. An environmental review process has been initiated that should reach the project approval stage in November 2017.

California’s Sustainable Groundwater Management Act

At RMC Water and Environment, professional engineers and other experts partner with communities throughout California to manage groundwater and other water-related concerns. Recently, RMC Water and Environment helped coauthor the Sustainably Managing Groundwater manual for the American Water Works Association.

A major component of California’s water resources, groundwater accounts for nearly 40 percent of the state’s overall supply. Importantly, such water becomes even more essential in drought years, when it makes up more than 45 percent of total supply. What’s more, certain Californian communities rely entirely on groundwater to sustain them.

In light of these important facts, California passed the Sustainable Groundwater Management Act (SGMA) of 2014, which transfers power over groundwater management from the state to the local level. SGMA mandates that local officials create groundwater sustainability agencies for the purpose of groundwater monitoring and for drafting oversight plans tailored to local conditions. The legislation gives communities up to two decades to produce and execute such plans.

What Does It Take to be a Green Business?

Energy Efficiency
Energy Efficiency

RMC Water and Environment is a California-based environmental engineering company that concentrates on protecting and managing water. The company provides unique design solutions to address local concerns about conservation, efficiency, and water cleanliness. Due to its conservation and awareness efforts, RMC Water and Environment’s Irvine office was named a certified green business by the Irvine Chamber of Commerce in 2016.

Six different criteria must be met to certify a company as being green. A business has to make environmentally-friendly purchases, be energy efficient and conserve resources, investigate and promote the use of alternative transportation (such as buses or bicycles), prevent pollution, conserve water, and train its staff in awareness of environmental issues.

Once the business is recognized as meeting all of the above requirements, it can be certified. Green practices may result in reduced energy costs as well as access to tax credits and rebates. The certification includes a mention on the Irvine Chamber of Commerce’s website, a press release, and social media coverage of the achievement. The certification is an incentive for businesses to help the environment and save money by doing so.
