Harris County MUD 502 Water Conservation Update: Transition from Stage 2 to Voluntary Stage 1 Restrictions

Dear Customer:

Harris County Municipal Utility District No. 502 (MUD 502) has rescinded Stage 2 (mandatory) and re-initiated Stage 1 (voluntary) water conservation measures for potable (drinking) water.

Stage 1 (Voluntary) water use restrictions now in place:

  1. Water Customers are requested to limit all outdoor water usage, including, but not limited to, lawn and garden watering, car washing, and window washing to evennumbered days for Customers with even-numbered addresses and odd-numbered days for water Customers with -odd-numbered addresses, and only between the hours of 10:00 am to 6:00 pm, and 12:00 midnight to 6:00 am. In the event no street address exists, Customers living on the north and west side of a street should use water outdoors only on even-numbered days and Customers living on the south and east side of a street should use water outdoors only on odd-numbered days.

Please check the settings on the controller for your irrigation system to make adjustments to the dates and times the system runs to implement these requested changes. Please note that the Towne Lake Community Association uses non-potable water from the lakes for irrigation of certain common areas throughout the Towne Lake community, which helps to reduce demand on the potable water system and preserve the availability of potable water for other uses.

MUD 502 will continue to monitor potable water use and will provide another notice if the drought stage changes or if Stage 1 drought conditions have been lifted. Please keep in mind that, despite the recent cooler, wetter conditions, the Houston metropolitan area remains in drought conditions. As a result, the MUD 502 Board continues to strongly encourage all residents to carefully monitor their water usage and continue to voluntarily conserve potable water. The MUD 502 Board of Directors appreciates your cooperation and perseverance during this challenging time.

Notice of Stage 1 Drought Conditions

Please be advised that the Master District has triggered Stage 1 (voluntary reductions) of its Drought Contingency Plan due to the ongoing drought conditions and is requesting that all potable water users reduce their usage immediately.

Potable water usage is increasing rapidly in the Master District’s Service Area (consisting of Harris County MUD Nos. 500, 501, 502, and 503), and under the Master District’s Drought Contingency Plan, we may be required to implement mandatory water use restrictions if conditions continue to worsen. The Master District encourages each Participant to implement one or more drought response measures in your Drought Contingency Plan, as applicable. We will continue to monitor potable water use and will provide another notice if the drought stage changes or if Stage 1 drought conditions have been lifted.

We appreciate your cooperation during this challenging time. A copy of correspondence sent to customers within Harris County MUD No. 500, as a Participant District, is attached.


Dear Customer:

Due to ongoing drought conditions, Harris County Municipal Utility District No. 500 (MUD 500) has initiated Stage 1 (voluntary) water conservation measures for potable (drinking) water and is requesting that all potable water users reduce their usage immediately. Potable water usage is increasing rapidly and under MUD 500’s Drought Contingency Plan, we may be required to implement mandatory water use restrictions if conditions continue to worsen. Last summer, when we requested voluntary conservation, you answered the call and were able to ensure a continued sufficient water supply for the Towne Lake community. Now that drought conditions have returned, we need your help again to reduce potable water usage and avoid the need for mandatory restrictions!

Stage 1 (Voluntary) water use restrictions now in place:

Customers are requested to voluntarily limit all outdoor potable water usage, including, but not limited to, lawn and garden watering, car washing, and window washing, as follows:

  1. District residents and other users of water within the District with even-numbered addresses should use potable water outdoors only on even-numbered days, and District residents and other users of water within the District with odd-numbered addresses should use potable water outdoors only on odd-numbered days. In the event no street address exists, District residents and other users of water within the District lining on the north and west side of the street should use potable water outdoors only on even-numbered days, and District residents and other users of water within the District on the south and east side of the street should use potable water outdoors only on odd-numbered days. District residents and other users of water within the District with irrigation controllers that do not have an even-odd option should use potable water outdoors no more than every other day.
  2. Potable water should not be used outdoors for irrigation or other uses in the morning between the hours of 6:00 am and 10:00 am, and in the evening between the hours of 6:00 pm and 12:00 am (midnight).

Please check the settings on the controller for your irrigation system to make adjustments to the dates and times the system runs to implement these requested changes. Please note that the Towne Lake Community Association uses non-potable water from the lakes for irrigation of certain common areas throughout the Towne Lake community, which helps to reduce demand on the potable water system and preserve the availability of potable water for other uses.

MUD 500 will continue to monitor potable water use and will provide another notice if the drought stage changes or if Stage 1 drought conditions have been lifted. The MUD 500 Board of Directors appreciates your cooperation and perseverance during this challenging time.

Summer Water Usage and Conservation Tips

Recently the Houston area has been experiencing hotter and drier than normal weather conditions, which has resulted in an increased demand on our water system. Please know that Harris County MUD No. 500, as Master District (MUD 500), is aware of the lower water pressure in its Service Area within the Towne Lake community during peak times, such as 4:00 a.m. to 7:00 a.m. MUD 500’s operator, Environmental Development Partners, has been conducting an investigation for any possible system irregularities and is reviewing several options to help alleviate the loss of pressure. As a community there are some ways you can help reduce demand during those peak usage times by varying domestic usage:

  • • Landscape irrigation is the largest demand on our system. If you have an irrigation system, change your irrigation times to earlier hours in the morning such as between 1:00 a.m. and 4:00 a.m., or move the time to 9:00 p.m. or later at night.
    • Over irrigating is the also one of the largest sources of overuse in our water supply. Want to know how long and how much to water? Check out https://www.watermyyard.org/#/Location
      There is a Cypress weather station monitored by Texas A&M AgriLife that provides watering recommendations.
  • Consider showering at night instead of in the early morning hours.
  • Run your dishwasher or washing machine during the day or just before going to bed at night.

You also can help do your part by ensuring you are using water wisely. In the Towne Lake Community, MUD 500 has partnered with the Towne Lake Community Association to allow the Association to use the water from the lakes to irrigate the medians and green spaces to minimize impact to our drinking water system. Among residents, a family’s water use can double or even triple during the warm summer months due to the impact of outdoor watering and irrigation, which can lead to significantly higher water bills. Here are some tips to help save water, and as a result, to help save you money.

Boil Water Notice Rescinded

On 2/17/2021, the Texas Commission on Environmental Quality required the Harris County Municipal Utility District 502 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? Some guidance is available at https://www.cdc.gov/disasters/watersystemrepair.html and https://houstonemergency.org/wp-content/uploads/Boil-Water-Notice-2292020.pdf.

Water Supply Update

The Harris County MUD 500 Master District Service Area, including Harris County MUD Nos. 500, 501, 502, and 503, remain under a boil water advisory at this time.

As you may have heard, the City of Houston has lifted its boil water advisory. The City supplies potable water to the West Harris County Regional Water Authority (Authority), which in turn supplies water to the Master District.

The Authority and the Master District now are taking the steps necessary to lift their respective boil water advisories, including water sampling. If the results are satisfactory, the Authority and the Master District may be able to lift their boil water advisories this evening or tomorrow, February 23rd. We will provide updated information as soon as it is available.
