Reclaimed Water Connections
Reclaimed water is non-potable and used for commercial purposes such as industrial cooling, construction washdown, dust control and concrete mixing. Loudoun Water manages connections to the reclaimed water system to support long-term sustainable operation, year-round nutrient management, and system reliability. Reclaimed water supply availability and hydraulic constraints may limit or exclude proposed connections that are not in alignment with Loudoun Water’s program goals. Capacity allocations and construction permits for reclaimed water connections are made in Loudoun Water sole discretion. Loudoun Water continually monitors system performance and customer activity. The reclaimed water system may be expanded in the future to best achieve program goals.
Reclaimed Water Program History
In 2010 Loudoun Water constructed the first pipelines of the reclaimed water distribution system to supply irrigation and industrial cooling water to Loudoun County’s rapidly growing data center industry. The reclaimed water distribution system has since expanded to 20 miles of pipeline. In 2025, Loudoun Water delivered more than 750 million gallons of reclaimed water to customers, helping to save an equal amount of potable drinking water while reducing nutrients discharged to the Potomac River and Chesapeake Bay.
Flushing and Maintenance
Loudoun Water service crews flush the reclaimed water distribution system annually and perform routine maintenance and inspections on hydrants, valves, and other appurtenances. Flushing the reclaimed water system helps to ensure the best possible water quality for our customers. Reclaimed water customers are given advanced notice of flushing and maintenance activities. Strong communication with our stakeholders helps ensure efficient fieldwork that minimizes impacts to business.
Water Quality
Reclaimed water is continuously monitored and tested to ensure that its quality meets Level 1 standards, the highest-level quality designation. Water quality information is available by request. If you would like reclaimed water quality information, please email Micah Vieux, Business Programs Manager.
