Thousands of gallons of water will now be recycled at the Marine Corps Recruit Depot (MCRD) in San Diego thanks to a new water reuse system. Living Machine Systems technology installed at the depot will treat wastewater and put it back to work for sub-surface irrigation, minimizing water use in the dry Southwest.
The system works by extracting waste water from the existing sewer line and treating it to meet rigorous water reuse standards for the state of California. The on-site Living Machine system will recycle 10,000 gallons of sewer-mined wastewater per day. The system draws on the use of tidal wetlands to accelerate the treatment process. According to the company, the system uses the least amount of energy and returns the highest quality of water.
“To the thousands of recruits and their families who attend graduation ceremonies at the base, the Living Machine system will appear simply as a lush, tropical landscape feature near the parade ground and statues honoring marine drill instructors,” Will Kirksey, global development officer at Living Machine Systems, said in a statement. “But the system’s real value is as an ecological water reuse system that ensures lasting water sources for both the military and the surrounding community.”
The system is said to be particularly useful in drought-prone areas like California. The use of the new technology will reduce the demand for imported fresh water and protect the environment from new pipelines that would need to be constructed to deliver that water.
