Extensive sewer system upgrades for Nashville, Davidson County

WASHINGTON, DC - As a result of a recent settlement, the Metropolitan Government of Nashville and Davidson County (Metro) will make extensive improvements to its sewer systems to eliminate unauthorized overflows of untreated raw sewage and to control overflows of combined sewage and stormwater.

According to the investigation, Metro has been unlawfully discharging over 200 million gallons of untreated sewage and experiencing overflows of billions of gallons of combined sewage into the Cumberland River and its tributaries.

The upgrades are expected to cost between $300 million and $400 million and will eliminate approximately 1.3 million pounds of pollutants per year.

The proposed consent decree is subject to a 30-day public comment period and final court approval before becoming effective.

The EPA presented the award to the Caltrans Stormwater Management Program at the National Clean Water Act Recognition Awards Ceremony in October.

Results of two-year stormwater runoff project released

SCOTTSDALE, AZ - AbTech Industries recently announced the final results of a two-year effort to protect Long Island Sound. The Filter Project, an EPA-funded initiative, was a collaboration between AbTech, the Long Island Soundkeeper, and the public works office to improve the city of Norwalk’s stormwater management program.

More than two hundred catch basins in South Norwalk were fitted with AbTech’s Smart Sponge® Plus filtration system to catch trash, debris, animal waste, hydrocarbons, oil, grease and bacteria before they could enter the Sound. Over the two-year endeavor, a total of 37,976 pounds of trash and debris were removed from the filters after three rounds of filter maintenance and cleanings.

Water quality analysis showed the filters effectively destroyed up to 95.9% of E. coli and absorbed 70.5% of oil and grease.

DuPont supports water quality initiative

DES MOINES, IA - DuPont recently announced a pledge of $250,000 to The Nature Conservancy in an effort to improve water quality in Midwestern watersheds and to further reduce excess nutrient runoff from agricultural fields.

DuPont is a charter member of the Conservancy’s effort to establish watershed monitoring and best management practices in the Boone River watershed in Iowa and the Mackinaw River watershed in Illinois. Information gathered from these projects will be used in watershed projects in other agricultural areas.

The $250,000 grant from DuPont will match funds pledged by The Kresge Foundation to the Campaign for Conservation: Saving the Last Great Places in Iowa. It is contingent on the Conservancy reaching its $9.5 million campaign goal by Feb. 1, 2008.

Santa Monica project wins stormwater management award

COSTA MESA, CA - The California Stormwater Quality Association (CASQA) has chosen the Santa Monica Westside Water Quality Improvement Project as its 2007 Outstanding Stormwater Best Management Practices (BMP) Implementation award winner in the subcategory of Treatment Control/Structural BMP Implementation.

Development and implementation of the urban runoff quality treatment facility, which was constructed deep beneath Mar Vista Park in western Los Angeles, demonstrated exceptional cooperation between two California cities to cost-effectively alleviate pollution caused by urban runoff in parts of both Los Angeles and Santa Monica.

The Westside project was initiated in an effort to improve water quality to benefit Ballona Creek, Santa Monica Bay and local beaches. The new facility treats 100 percent of the dry weather flow (2 to 3 cubic feet per second) and up to 36 cubic feet per second of wet weather flow. It removes a variety of solid, liquid and soluble pollutants. The facility was designed with no moving parts, chemical additives or electrical power requirements.

Design, permitting and construction support services for the environmentally responsible facility were provided by Black & Veatch.
