Latest News

The following is a message from the West Harris County Regional Water Authority, which supplies water to the Harris County MUD 500 Service Area, including Harris County MUD Nos. 500 (for its internal boundaries), 501, 502, and 503.

The WHCRWA has resumed normal operations. Thank you for your cooperation and assistance during the course of the freeze event!

Prepare for the Freeze

  • Disconnect all garden hoses from the outside spigots.
  • Wrap or cover and tape all exposed water pipes, including outside spigots.
  • Wrap pipes in the attic, especially if they are under an eave leading into the house. While they are not exposed to the outside, they can freeze quickly.
  • Securely close the lid on your meter box to keep out freezing winds.
  • If you have an irrigation system, turn off the water at your backflow preventer and drain the system. Wrap the backflow preventer as well.

Notice of Lifting of Stage Drought Conditions

Please be advised that the Master District has lifted Stage 1 (voluntary reductions) of its Drought Contingency Plan. The West Harris County Regional Water Authority, which provides potable water to the Master District, also has lifted Stage 1 (voluntary reductions) of its Drought Contingency Plan. A copy of correspondence sent to customers within MUD 500, as a Participant District, is attached.

The MUD 500 Board would like to express their sincere thanks for your cooperation in voluntarily reducing your water usage. Because of your action, MUD 500 was able to ensure sufficient capacity in its potable water system to meet the needs of the growing Towne Lake community. We wish you and your family a safe and happy holiday season.
