Freeze damage preparation and repair tips

H2O Innovation staff will be mobilized and standing by to deal with water main breaks and water plant issues. If you experience a pipe freeze on your side of your water meter outside your home, H2O can only turn your water off at the meter. If you have a pipe broken inside your home, you can isolate your private cut off usually located on the side of your home below your water spigot. Or inside the garage. It’s a good idea to have the names of a couple of plumbers should you need them. As H2O does not repair homeowner private water lines.

Freeze Preparation Tips

  1. Wrap outdoor and garage pipes.
  2. Remove water hoses and wrap water spigot.
  3. Drain and turn off sprinklers system.
  4. Turn off water to your washer if in garage.
  5. If you leave your house before a freeze, turn off the water at your private cut off valve and leave your heat on.

Protect your pipes when it freezes

  1. Open cabinets under sinks to let your house’s heat warm the pipes.
  2. If your pipes freeze, turn off the water at your private cut off valve. This prevents broken pipes from leaking into house after they thaw.
  3. Let faucets drip from the cold and hot taps or run water through your indoor faucets before you go to sleep.

***Check your Insurance coverage. Flood insurance does not pay for damaged caused by freeze.

Read the Notice – NW HC MUD 23 Monitoring Requirements Not Met


Dear Residents,

Our system failed to collect every required coliform sample. Although this incident was not an emergency, as our customers, you have a right to know what happened and what we did to correct this situation.

We are required to monitor your drinking water for specific contaminants on a regular basis. Results of regular monitoring are an indicator of whether or not our drinking water meets health standards. During January 01, 2022 to January 31, 2022 we did not complete all testing for coliform bacteria according to TCEQ rules and regulations and therefore cannot be sure of the quality of your drinking water during that time.


There is nothing you need to do at this time. You may continue to drink the water. If a situation arises where the water is no longer safe to drink, we are required to notify you within 24 hours.


Issue resulted from recent rules and regulations changes within TCEQ. TCEQ is now not accepting a well sample as part of the routine Monthly Bact’s. In January 2022, we were required to sample 5 Routine Sites, but since we counted the well sample taken as one of the five, we were in violation. We have notified the laboratory in charge of conducting these samples and ensured proper sampling will be conducted from now on. North West Harris County MUD 23 has collected every required coliform sample for the month of January 2022 and are no longer in violation.

If you have any questions regarding this matter or need further information, contact: Natalia Espitia with H2O Innovation at (281) 355-1312 or at 2200 Sciaaca Road, Spring, TX 77373.

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