The Orange County Water District (OCWD) has been a leader in the recycled water movement. Its Groundwater Replenishment System (GWRS) operates as a possible model for the potable reuse systems of the future, taking treated wastewater that would normally be discharged into the ocean, purifying it, and then piping it into “recharge stations” where it is stored in underground aquifers for at least six months before traveling to consumers (that buffer puts the “indirect” in indirect potable reuse).
The Water Research Foundation (WRF) has initiated a research project titled “Blending Requirements for Water from DPR Treatment Facilities” which, as the name indicates, aims to determine the optimum phase for incorporating highly treated direct potable reuse (DPR) water into the larger supply.
It was named by the infamous explorer Captain John Smith after the Massachusett tribe of Native Americans, then subsequently renamed by King Charles I of England after himself. As Boston grew, the mighty Charles River proved a vital force behind its expansion, and its long and winding history a reflection of the city’s own.
The Silicon Valley Advanced Water Purification Center project provides expanded reuse opportunities, increased sustainability, and promise for the future.
What the road to full resource recovery looks like and how to get on it.
California’s drought, increasing water consumption, and improving technology costs are sparking deployment of more advanced municipal and industrial solutions to address water stress across the U.S. The epicenter of change is across the U.S. Sunbelt, where wastewater reuse and desalination have been thrust into the spotlight as key solutions.
The Water Environment Federation (WEF) is harnessing both natural resources and human drive to lead an energy surge in the water sector. WEF President Ed McCormick discusses where the industry is headed and how utilities can stay ahead of the curve.
An environmental study made headlines this spring as it drew a distinct parallel between the growing PPCP epidemic and a poisonous disinfection byproduct (DBP) making its way into drinking water.
Zero Liquid Discharge (ZLD) systems employ cutting-edge technologies to minimize water use within a given industrial facility and maximize the reuse of its processed wastewater. In the perfect ZLD system, no effluent ever leaves the factory, savings are immense, discharge and reuse requirements are met with ease, and the praise of conservation groups is bestowed fervently.
It supplies drinking water for more than half of the total U.S. population and greater than 95 percent of the rural population. It helps grow our food because more than 60 percent of it is used for irrigation to grow crops. It's an important component in many industrial processes, and it’s a source to recharge lakes, rivers, and wetlands.
