Boil Water Notice Rescinded

On 2/17/2021, the Texas Commission on Environmental Quality required the Harris County MUD No. 120 public water system, PWS ID TX1010774, to issue a Boil Water Notice to inform customers, individuals, or employees that due to conditions which occurred recently in the public water system, the water from this public water system was required to be boiled prior to use for drinking water or human consumption purposes.

The public water system has taken the necessary corrective actions to restore the quality of the water distributed by this public water system used for drinking water or human consumption purposes and has provided TCEQ with laboratory test results that indicate that the water no longer requires boiling prior to use as of 2/22/2021.

If you have questions concerning this matter, you may contact the District’s operator, Environmental Development Partners at 832-467-1599 or toll free at 1-866-467-1599.

Water Transmission and COVID-19

According to the Center for Disease Control (CDC), the COVID-19 virus has not been detected in drinking water. Conventional water treatment methods that use chlorine disinfection, such as those in Harris County Municipal Utility District No. 120’s drinking water system, should remove or inactivate the virus that causes COVID-19.
