Wildlife Management in Harris County MUD 500 Lakes

On September 14, 2025, MUD 500 received a report of a confirmed sighting of an alligator in the central portion of MUD 500’s lakes, between Greenhouse Road and Puckett Island. MUD 500 immediately notified its wildlife management contractor of the sighting and directed the trapper to actively monitor for an alligator and, if one is located, to immediately remove it upon obtaining the required nuisance permit from the Texas Parks and Wildlife Department. The District respectfully requests that residents of and visitors to Towne Lake refrain from interfering with its wildlife management contractor and/or any of the contractor’s lines, traps, or other equipment left in or near its lakes.

MUD 500 continues to request that residents report any sightings of alligators to its operator, Inframark, at (832) 467-1599. MUD 500 encourages your district to share this information with your residents. Please visit MUD 500’s website, at http://www.hcmud500.org, for additional information.

HCMUD 501 Air Scouring Residential Notice

Dear Residents of Harris County Municipal Utility District 501

We are writing to inform you that your water services may be interrupted in the next weeks due to essential maintenance work on the water mains in your neighborhood. The work involves cleaning the water mains to remove scale and mineral deposits that accumulate over time and can cause reddish or dis-colored looking water. While the discoloration is harmless and caused by natural mineral oxides, it is important to maintain clean water mains for the quality of your water supply.

How Does It Work? We will be using a method called “Air Scouring” to clean the mains. This method is efficient and causes minimal disruption. Here’s how it works:

  1. Isolation: We close the valves at either end of a section of the main.
  2. Air Supply: An air supply hose is attached to a fire hydrant at one end of the closed-off section.
  3. Agitation: Clean, high-volume air is pumped into the hydrant, agitating the water and loosening mineral scale.
  4. Scouring: The loosened material acts as a scouring agent, further cleaning the pipe.
  5. Flushing: We open the water supply valve slightly to maintain the process. The open hydrant will eventually release clear water, indicating the cleaning is complete.

Your Role:  We understand that water service is crucial, and we apologize for any inconvenience. Your cooperation is essential to ensure the job is completed efficiently:

  1. Meter Turn-Off: We will turn off every meter during this process to prevent debris from entering your house line.
  2. Flushing Your Line: After the work, please open an outside faucet to flush any residue from your house plumbing. This should only take a few minutes.
    • Do not open inside sink faucets to avoid clogging sink aerators.
    • Avoid opening hot water faucets to prevent debris from entering your water heater.

Appearance of Water: In some instances, the water may appear “milky” due to air in the water. This condition is temporary and should clear quickly.

We appreciate your understanding and cooperation during this maintenance work. Should you have any questions or concerns, please do not hesitate to contact us.

Thank you for your assistance and patience.

Sincerely,

Amanda Benzman
Senior Account Manager
