Reclaimed water is safe for non-potable uses such as industrial cooling, construction washdown, dust control and concrete mixing. For new construction or retrofitting, approved construction plans and valid permits are needed to connect to the reclaimed water system. Loudoun Water engineers are available to guide customers through the connection process and to provide additional information on special requirements, including signage, labeling, and backflow prevention.

Reclaimed Water System
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 2023, Loudoun Water delivered 815 million gallons of reclaimed water to customers, helping to save an equal amount of precious 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.
