Kentucky Sewage Project Enhances Community
July 10, 2020
Louisville’s Combined Sewer Overflow (CSO) was not meeting standards set in the Clean Water Act, as storms would frequently lead to sewage discharging in local inland waterways. To mitigate the problem, the Louisville/Jefferson Country Metropolitan Sewer District embarked on the $78 million Southwestern Parkway Combined Sewer Overflow Basin project, which uses “capture and release” technology......

Down in New Orleans officials are experimenting with how to restore decades of wetlands that have been lost due to rising salinity levels in the surrounding bayous.

In an effort to clean up U.S. water sources, federal standards mandate upgrades to stormwater infrastructure that prevents runoff pollution. To meet compliance standards, the highly-developed Washington, D.C. suburb of Prince George’s County, Maryland county must convert close to 5 percent of the county’s total area, or 15,000 acres in total, of watertight surfaces into......

Los Angeles is no stranger to water shortages and has been using recycled water since the 1960s for irrigation, industrial processes, cooling, and habitat restoration. However, it was only recently that L.A. and surrounding municipalities have banded together with a “one water” policy to become a coordinated, water-wise region. The Los Angeles Department of Water......

The Philadelphia Water Department has its share of old water pipes to contend with – in fact, they have increased investment in water pipes by 25 percent in their latest capital improvement program. However the Department’s Strategic Energy Plan also looks to better manage future expenses – it includes a facility that will extract energy......

Energy is one of the most expensive costs for wastewater treatment, but DC Water’s Combined-Heat-and-Power (CHP) facility is setting out to change that. DC Water’s largest recycling project will “pressure cook” the leftover organic matter, introduce bacteria to spur the anaerobic digestion of the solids, then the resulting methane will be captured to create electricity......
Alleys that Drink Stormwater Runoff
February 16, 2017
The city of Boston recently completed a new 508-square-foot “porous alley” that absorbs stormwater and filters it into the ground, rather than allowing it to make its way into the sewer system where it has to be treated. Construction of the alley is part of a larger effort to boost the quality of water in......
