- Fairfax County’s award-winning Wastewater Management Program is celebrating Infrastructure Week from September 14 - 18, 2020. For more than 50 years, dedicated wastewater program employees have successfully operated, maintained, repaired and restored the wastewater system in the county. Additionally, the system capacity has increased to meet the ongoing growth and long-term needs of residential and commercial users to provide current and future customers with reliable sewer services at competitive sewer rates.
Staff perform sample collection and testing
- Fairfax County recently conducted intensive testing to develop local discharge limits for various pollutants entering the publicly owned treatment works (the Noman M. Cole, Jr., Pollution Control Plant) that has been in operation since October 1970. The results of this testing are used to limit the introduction of harmful chemicals and substances into the sewer system that may damage the integrity of the treatment works, cause blockages and overflows or pass through the treatment works and harm the environment.
