Boil Water Notice for Community Public Water Systems

Harris County MUD 18 PWS TX1010512 has received the following notice from the North Harris County Regional Water Authority.

Due to reduced distribution system pressure resulting from the inability of the City of Houston to supply water to the North Harris County Regional Water Authority (the “Authority”),TX1013298, the Texas Commission on Environmental Quality has required the wholesale customers of the Authority to notify all customers to boil their water prior to consumption (e.g., washing hands/face, brushing teeth, drinking, etc).Children, seniors, and persons with weakened immune systems are particularly vulnerable to harmful bacteria, and all customers should follow these directions).

To ensure destruction of all harmful bacteria and other microbes, water for drinking, cooking, and ice making should be boiled and cooled prior to use for drinking water or human consumption purposes. The water should be brought to a vigorous rolling boil and then boiled for two minutes.

In lieu of boiling, individuals may purchase bottled water or obtain water from some other suitable source for drinking water or human consumption purposes.

When it is no longer necessary to boil the water, the public water system officials will notify customers that the water is safe for drinking water or human consumption purposes.

Once the boil water notice is no longer in effect, the public water system will issue a notice to customers that rescinds the boil water notice in a manner similar to this notice.

Please share this information with all the other people who drink this water, especially those who may not have received this notice directly (for example, people in apartments, nursing homes, schools, and businesses). You can do this by posting this notice in a public place or distributing copies by hand or mail.

If you have questions concerning this matter, you may contact the District’s operator, Eagle Water Management, at 281-374-8989. The District is working diligently through the unprecedented weather event to maintain water system operation. Please reduce water consumption to reduce the demand on the District’s system.

Freezing Temperatures

Harris County MUD18 reminds residents to prepare for freezing temperatures.  Here are some areas to consider before a freeze:


Underground water supply pipes are buried below the frost line and will be safe from freezing

Prevent interior frozen pipes and damage to your home by opening the cabinet doors under kitchen and bathroom sinks to allow warm air to circulate and warm the pipes, especially overnight during freezing conditions.

Insulate outdoor faucets and exposed pipes, and be sure to disconnect hoses from outdoor spigots.  Make sure spigots are wrapped with insulation (foam insulation tape and a plastic bag) to prevent them from freezing.  Self-sticking foam-insulating tape or foam insulating tubes can be found at home supply stores.

Irrigation Systems

Shut off the water to an irrigation system.  In our area irrigation shut off valves are commonly found on an anti-siphon fixture that extends above ground somewhere in your yard.  There are usually 2 valves on this unit: one to shut off your water coming into the unit from the water main, and another to shut off water going out to the irrigation system.  After shutting off these valves, drain the anti-siphon unit itself by turning 2 set screws on small brass valves to release water trapped between the 2 shut-off valves.

Make sure the anti–siphon unit is also wrapped with insulation (foam insulation tape and a plastic bag) to help prevent water freezing inside the unit.

Finally, if you have an automatic system then you will need to shut down/turn off the controller or timer. Most irrigation controllers have a “rain-mode” which simply shuts off the signals to the valves. The controller continues to keep time, and the programming information isn’t lost (start times, valve run times, etc.) and the clock continues to run throughout the winter.  The only change is that the valves will not activate.  An alternative to using the rain mode is simply to shut off the power to the controller. If you do this, you’ll need to reprogram the time and potentially other settings come spring.


Protect plants from freezing by covering them with plant cover fabric, or a light blanket then, plastic sheeting on top of the fabric.  Hydrate plants early so they can absorb water and stay healthy through the cold.
