I was recently invited on a fascinating inspection visit to a couple of sites operated by the largest supplier of treated water in the United States: The Metropolitan Water District of Southern California
We first visited the Weymouth Treatment Plant, an impressive 150-acre site built in 1940, just before WW2 (thus its noted Mission Revival-style architecture).
The plant has a treatment capacity of 520,000,000 gallons per day: blending water delivered a combined 700 miles via the Colorado River Aqueduct and the California Aqueduct. It is also home to one of the world’s largest machine shops, housing some awesome toys.
We next visited the adjacent Water Quality Lab, which performs more than 320,000 water quality tests annually on samples gathered throughout the vast distribution systems, for the detection of bacteria, viruses, protozoan parasites, chemical contaminants, and toxins – thereby safeguarding the drinking water delivered to more than 19 Million Southern California residents every day.
An hour or so away, we entered the Advanced Purification Center: a high-security half-million gallon per day test facility, built as a proof of concept for near-future construction of a full-scale recycled water plant.
A unique application of membrane bioreactors significantly increases water recycling efficiency. If approved, this innovative system will have global applications, and greatly reduce dependence on imported water. The full scale initial planned construction can produce up to 150 million gallons of drinkable water daily, enough to serve 500,000 homes.
I was surprised that the MWD staff knew nothing about the Gates Foundation Omniprocessor initiative, given the inherent opportunities for cross-collaboration and mutual benefit. Then again, I was equally surprised how little attention has been paid by MWD to the opportunities for IP development and protection. Public utilities tend not to think of their own inventions and innovations as opportunities for IP and licensing growth. It is important, however, for publicly funded entities engaging in pioneering R&D to explore channels for revenue generation beyond taxpayer funding, which is subject to legislative redirection at any given time. The State of California has a history of developing globally impactful innovations, be it in water management, earthquake detection, or fire protection. Some of these innovations merit protection and consideration as foundations, upon which future R&D might be funded.
The inspection team on this infrastructure trip comprised some of the brightest and best of California leadership. Admittedly, some of the more complex engineering parlance flew over my head, but I learned an enormous amount, most notably that – once again – the State of #California is leading the way in finding and building new ways to distribute, treat, conserve, and maximize one of our planet’s most valuable resources.
