Boil Water Notice Rescinded

On 2/18/2021, the Texas Commission on Environmental Quality required the Fort Bend County MUD No. 185 public water system, PWS ID TX0790478, 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.

So, what do I do after the Boil Water advisory has been lifted?

  • Once the boil water alert has been lifted flush all fixtures (e.g., faucets, drinking fountains) and equipment and restart. Flush faucets and fixtures until detectable chlorine can be detected.
    • Flush for 1 minute.
    • Discard ice from ice machines and clean and sanitize per manufacturers’ instructions.
  • Remove point of use filters and flush outlets for several minutes before installing new filters (e.g., ice-machines, sinks and showers if present).
  • Run water softeners through a regeneration cycle.
  • Drain, disinfect, flush, and refill water storage tanks if needed.
  • Change pre-treatment filters, backwash carbon tanks, regenerate softener, and clean and disinfect RO membranes, disinfect dialysis distribution loops.
