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.

Turn chores into water-saving moments for your household. Most modern dishwashers use less water than it takes to wash dishes by hand.

Some EnergyStar certified machines use as little as three to five gallons of water per cycle. In comparison, washing by hand can use about three to five gallons per minute of washing. http://bit.ly/2ovQ98x

If you have an in-ground irrigation system, check it each spring before use to make sure it wasn’t damaged by frost or freezing. An irrigation system that has a leak 1/32nd of an inch in diameter (about the thickness of a dime) can waste about 6,300 gallons of water per month.

Yesterday before the snow started, we had a visitor from Loudoun Water (Erika) come and speak with our 7-12 year old homeschool students during class time. Erika explained a lot where our drinking water comes from and what happens to waste water and storm water. The students were very engaged and asked some great questions. Many thanks to Loudoun Water for coming out!

When temperatures drop, it's important to protect your home's pipes as much as possible, especially if you've experienced trouble in the past.

Preventative measures include:
- Monitoring the weather to know when to take precautions
- Allowing a faucet to drip cold water slowly when temperatures get below freezing to keep water moving through your meter and pipes
- Keeping your thermostat set to at least 55F, whether you're home or away
- Keeping doors, windows and garage doors closed and insulated
