Welcome to the neighborhood. As your water and wastewater service provider, Loudoun Water’s Mission is to provide sustainable water services to protect health, the environment and quality of life. We serve the residents and businesses in Eastern Loudoun and small Community Systems.

Loudoun Water was created to provide water and wastewater service to residents of the unincorporated eastern portion of the County. In May of 1959, the Loudoun County Board of Supervisors created the Loudoun County Sanitation Authority, doing business as Loudoun Water, by resolution, through the Water and Waste Authorities Act. We are an independent public service. All income is received either as user fees from customers or availability fees from developers. User fees pay for operating expenses. Availability fees pay for capital improvement projects. We receive no tax money.

We encourage you to visit our website periodically to learn more about your water and wastewater service. We've pulled links to commonly asked topics to make it easier for you, our new customers, to find on our website. You can also call customer service at 571.291.7880, Monday–Friday, from 8:00am to 5:00pm.
