The Harris County MUD 500 Master District Service Area, including Harris County MUD Nos. 500, 501, 502, and 503, remain under a boil water advisory at this time.
As you may have heard, the City of Houston has lifted its boil water advisory. The City supplies potable water to the West Harris County Regional Water Authority (Authority), which in turn supplies water to the Master District. The Authority and the Master District now are taking the steps necessary to lift their respective boil water advisories, including water sampling.
If the results are satisfactory, the Authority and the Master District may be able to lift their boil water advisories this evening or tomorrow, February 23rd. We will provide updated information as soon as it is available.
