The city is continuing the UDF program in certain areas of town in the upcoming months. Specific areas for flushing will be posted on the city website. Flushing will normally occur between the hours of 10 p.m. and 7 a.m.

The League City Water Production Department is implementing a common utility maintenance procedure called unidirectional flushing. It involves opening specifically-selected fire hydrants and closing specifically selected valves under controlled conditions to scour the inner surface of water distribution pipes.
The scouring process helps to remove corrosion scale and sediment that accumulate naturally over time. If otherwise left in place, these deposits could degrade water quality and restrict pipeline carrying capacity.
Though not intentional, this happens from time-to-time during the flushing program.
During flushing, certain valves are closed to provide control over the direction of flow. It is likely that a valve closure resulted in loss of supply to your block. The crew will be sent to your block immediately to investigate and identify which valves may be closed and need to be re-opened.
No, each residence and business is individually metered at the service connection to determine consumption. Your utility bill is based on your specific meter readings.
The color is due to the presence of solids that are scoured from the surface of the pipes. These may include sand, sediment, iron (rust), and manganese, all of which are naturally-occurring and common to virtually every water system. At the levels that cause mild discoloration, these solids are not harmful; although they may impart an undesirable taste to the water.
Customers are advised to fully open their cold water faucets in their kitchen and bathroom to flush this water out of their service piping and plumbing lines. In most cases, the water should begin to run clear again within a minute. If it does not clear, please let us know and we will have a crew sent to your house to investigate further.
Yes, water production staff has maintained compliance with all state and federal drinking water quality standards. We perform frequent quality assurance / quality control monitoring throughout the system to ensure the safety and aesthetic quality of your water.
Each year, water production staff prepares the consumer confidence report for all our customers. This report summarizes the results of testing and provides a comparison to regulatory standards. We are performing flushing as a proactive measure to further enhance water quality and help ensure continued compliance.
League City Water Production strongly values, encourages, and practices water conservation measures. In developing the flushing program, we considered the impact of water use and weighed it against the known benefits of flushing. While a fair amount of water is used and is necessary to create an effective scour, we use a flushing practice called unidirectional flushing that is specifically designed to reduce overall water usage.
Because water mains are designed to handle fire flow, which may be several times larger than domestic or commercial water flow, the velocity of flow (or rate that water flows through pipes) in most mains is normally fairly low. Due to this, solids may settle on the bottom of the pipes. The problem may be more significant where there are dead-end pipes or areas of low water use.
Over time, these deposits reduce the “carrying capacity” of the pipe. They can also be a source of color, odor, and taste problems in the water if the deposits are stirred up by increases in the flow. Flushing the pipes at high velocities will normally remove most of the settled substances and discolored or stale water.
During the actual flushing process, water customers may experience some disturbance in their usual water service such as a short-term decrease in water pressure or the appearance of “brown water.” Although the water should not pose a health risk, it is best to avoid drinking the water until it runs clear from the tap.
Avoid washing clothes while flushing is happening in your area and don’t wash if there is a brown tint to the water. Plan ahead and do your laundry over the weekend to avoid the possibility of having stained clothes. If you inadvertently have washed your clothes in “brown or discolored water,” do not use bleach. This will set the stains in your laundry.
Don’t prepare baby food or formula if the water is discolored. Use bottled water or pre-prepared food and formula. You can also boil the water for one minute to ensure safety.
It’s often a good idea to use water stored in the refrigerator to drink, even when the flushing program is over. This a good habit to get into in the case of an emergency.
