The City of Warrenton produce 317,566,020 gallons of water in 2018, an average of 870,043 gallons per day. This is about 41% of the engineer's defined production capacity of the system. The City maintains 4 deep wells, 6 water storage tanks, and 2 booster stations with a total storage capacity of 2,450,000 gallons of water. Water loss has been reduced from 28% in 20105 to 13% in 2018 through prompt repair of water leaks, replacement of aging infrastructure, and through the City's Water Meter Replacement Program.

The Water Meter Replacement program has a goal to maintain all meters to be under 15 years of age to ensure proper metering. Old meters are replaced by the City at no cost to the owner. Since 2015, 823 water meters have been replaced, which is 24% of 3,400 water meters monitored each month. 

The City sends 9 water samples each month to the DNR Laboratory in Jefferson City for testing. These samples are taken from random locations throughout the City. The Warrenton Water Department also has a Backflow Prevention ordinance and Wellhead Protection Program in place to help ensure the production of safe and quality water to our customers.

Report A Problem

The Warrenton Water and Sewer Department’s policy is that the customer is responsible for their own system. The amount of water that goes through the meter will be billed to the customer for water and sewer charges. The Customer can check for leaks in their own system. There is a small red triangle on the face of the meter that is called the leak indicator. You need to make sure every faucet/water supply in the house is off (washing machine, faucets inside and outside, toilets, etc.)   Then look on the face of the meter at the leak indicator. You will have to watch this for at least 10 minutes. If you see any movement in the leak indicator, or if the number changes on the register, you have a leak.  The customer is responsible for sewer service lines at the property line or easement line; where the stop box and clean-out should be located. If you should have problems with either water or sewer from that point in, it will be for you, or the property owner to repair. The Warrenton Water and Sewer Department only maintains from those points out, as well as water and sewer mains. If the water meter breaks due to negligence such as freezing, you will be billed for the cost of a new meter.
