    Due to a loss of pressure in the City of Houston caused by a power outage, the Texas Commission on Environmental Quality has required that the following MUDs, City of Hilshire Village Harris County MUD 182 Harris County MUD 372 Harris County MUD 420 be notified to boil their water prior to consumption (e.g., washing hands/face, brushing teeth, drinking, etc) because your MUD receives water directly from the City of Houston. 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, you will be notified that the water is safe for drinking water or human consumption purposes. Once the boil water notice is no longer in effect a notice rescinding the boil water notice will be issued in a manner similar to this notice. For additional questions you can contact our Customer Care line at 281-579-4500.
