- The County’s Wastewater Management Program received what amounts to ‘gold’ in the industry by winning the National Municipal Stormwater and Green Infrastructure Awards in the MS4 Phase I Overall Category. The award for the MS4 program was presented at the Water Environment Federation’s annual WEFTEC Awards 2023 ceremony which recently took place in Chicago. With this win, the MS4 program is now recognized as the best in the country.
Wastewater Management Awards Ceremony
- There are more than 160,000 water and wastewater treatment plants in the United States. Given that number, it is an honor to receive recognition by the Water Environment Federation (WEF) as a Utility of the Future. Recently the Wastewater Management Program (WWM) received the distinction for its work at the Noman M. Cole Pollution Control Plant and its collection system, placing the facility among only 200 plants nationwide to be given the designation since its inception in 2016.
Lake Accotink
- More than 24 hours after bacterial testing began on the water in Lake Accotink following a sewage spill, results show bacteria levels are not elevated. This indicates the cleanup effort was done in time to prevent downstream contamination from reaching Lake Accotink. As a result, there is no continued concern regarding human exposure to untreated sewage in the lake.
