Planning & Monitoring
Financial and engineering planning are conducted to ensure funding and infrastructure are available to meet current and future wastewater needs. Analyses are conducted by the WWM Environmental Laboratory to ensure regulatory compliance with state and federal laws and to provide quality control in the treatment process. In addition to laboratory testing, ecosystem monitoring in and around the receiving waters is conducted. WWM also administers the National Pretreatment Program which regulates industrial users of the sanitary sewer system in accordance with the Clean Water Act to protect health, safety and the environment.
The county’s wastewater collection and conveyance system includes sanitary sewer lines, pumping stations, and flow metering stations. The county monitors these components and provides a 24-hour trouble response service for sewer backups.
All wastewater is treated using state-of-the-art physical, biological and chemical processes to remove pollutants and pathogens that are harmful to the environment. Wastewater from county homes and businesses is treated at one of several treatment facilities throughout the region. The county owns and operates the Noman M. Cole, Jr., Pollution Control Plant, located in Lorton, which treats approximately wastewater from homes and businesses
