Ultra-deep diamonds aren’t the type of glittering gems that jewelers covet. Instead, they are rough, oftentimes milky-looking minerals that travel up from the transition zone, a region hundreds of miles deep in the earth’s mantle. These precious stones are not only historical artifacts, formed some 90 million years ago, they  … Read More

The intersection of water and energy is an interface that in the water industry we often explore in terms of operational efficiencies, conservation policies, and cost perspectives. But on a micro scale, the water-energy nexus is encapsulated within a single molecule. And the research surrounding the separation of this molecule’s  … Read More

Potable Reuse Project Case Studies

Potable Reuse Project Case Studies

Potable Reuse Project Case Studies: Cloudcroft, NM, is a 110-year old mountain resort community in the southeast corner of New Mexico. Planning for direct potable reuse began immediately, says Powell, and initial construction began in 2005, but issues with contracting stalled the project by 2007. Now back on track, construction bids  … Read More

Membranes for Municipal Water and Wastewater Treatment

|

When it comes to water membrane technology, there are currently four different types of membranes, three of which are frequently used for municipal water and wastewater treatment.

Four Membrane Types
The first two classifications are microfiltration and ultrafiltration. The microfiltration and ultrafiltration processes use low-pressure membranes, either immersed in aeration tanks, using  … Read More

Throughout American history, infrastructure investment has been considered an issue central to national prosperity. Over the centuries, it has breathed new life into a stalled economy, it has fueled the nation’s industrial expansion, and has proven a positive, unifying force.

In 1817, John C. Calhoun urged congressmen to “bind the Republic  … Read More

“It takes a lot of water to make electricity and it takes a lot of electricity to pump, move, and, now, recycle and reuse water,” writes Joe Grindstaff, general manager of Inland Empire Utilities Agency (IEUA) on the interconnectedness of these two resources.

IEUA provides wastewater collection and treatment services  … Read More

Maintaining an Underground Potable Water Tank

Maintaining an Underground Potable Water Tank

|

Underground potable water tanks can be a cost-effective way to store healthy drinking water, but only if they are maintained properly. To reduce operating costs and conserve water, tanks must be inspected, cleaned, and maintained regularly. Documentation must be accurate, consistent, easy to analyze, current, and accessible to be a  … Read More

Buckminster Fuller, considered one of the greatest minds of our times, developed several technologies and strategies that improved human lives by doing more with less. He called this concept “ephemeralization.” In today’s world, amid increasing climate variability, population growth, and water scarcity, Fuller’s approach seems more necessary and relevant  … Read More

Strategies for Preventing Non-Revenue Water Loss

Strategies for Preventing Non-Revenue Water Loss

Lack of dedicated utility funding for non-revenue water is a perceived barrier to progress. “The irony is that NRW reduction actions don’t have to be funded out of stressed operating budgets where funds may be already tight,” says Dickinson. “They can be funded out of capital improvement programs or performance-based  … Read More

How to Clear Contaminants From Water Naturally

How to Clear Contaminants From Water Naturally

|

The cost of energy isn’t the only expense on the mind of water municipalities. The cost to treat drinking water is increasing as runoff from farmland and lawns pours chemicals, nitrates, phosphates, and synthetic compounds into the supply. When water runoff flows into lakes, streams, ponds, and oceans, it can negatively impact water conditions, affecting fish, livestock,  … Read More

All About the Cycle Stop Valve (CSV)

All About the Cycle Stop Valve (CSV)

|

What happens is that the CSV opens and closes like a ball valve—it uses a spring to push it open and then a diaphragm will push it closed. The beauty of this is that the customer sets the valve at the required outgoing pressure, and that’s where it stays. So,  … Read More
