Loudoun Water

Loudoun Water Providing water and wastewater services to residents of unincorporated areas of Loudoun County for more than 50 years.

In May of 1959, the Loudoun County Board of Supervisors created Loudoun County Sanitation Authority, doing business as Loudoun Water, by a resolution, through the Water and Waste Authorities Act, for the sole purpose of providing water and wastewater service to residents of the unincorporated areas of Loudoun County. These areas are generally the communities east of Route 15 and some communities south of Route 50 to the County line. Loudoun Water is a political subdivision of the State, just like a Town or a County. All income is received either as user fees from customers or as availability fees from developers. User fees pay for operating expenses. Availability fees pay for capital improvements. Loudoun Water receives no tax money. This page is monitored Monday - Friday, 8:00 a.m. - 4:30 p.m. In the event of an after-hours emergency requiring immediate assistance, please call our after hours staff at 571.291.7878.

Mission: We provide sustainable water services to protect health, the environment and quality of life.
