Dear Harris County MUD #489 Resident,
On September 24, 2021, Harris County MUD 418 public water system, (PWS) ID 1013329 planned to convert four sections of Harris County MUD 489 served by Water Plant #1 to Water Plant #2. The goal is to provide demand relief at Water Plant #1. While performing the work, we came across a valving issue and ceased work for time to investigate, correct the problem and reschedule.
The main difference between the two sources is the required disinfectant. Surface water requires chloramines (a mix of chlorine and ammonia), while groundwater calls for free chlorine. Public water systems are required to properly disinfect their water and maintain an adequate disinfectant residual in the distribution system. Free chlorine is widely used as a disinfectant because it persists for long periods, while also limiting the formation of disinfection by-product contaminants.
At this time, the issue has been resolved and the conversion is set to take place on Friday, October 8, 2021. During this period, you may experience taste and odor changes associated with this type of disinfectant conversion that may last up to two weeks. While we do not anticipate any service outages during this transition, please be prepared for unexpected disruptions between the hours of 10:00 am and 1:00 pm.
The sections that will be affected include:
- Mission Tejas
- Enchanted Rock
- McKinney Falls
- Goose Island
