Notice to Purchaser of real property in the District.

Water Quality

Regulations of the Texas Commission on Environmental Quality (TCEQ)  require Harris County MUD No. 81 to regularly evaluate the quality of drinking water.

See the summary of the report.

Emergency Water Rationing

When the district pumps three times its average on three consecutive days, water rationing is imposed. There are three levels of water rationing:
  • Voluntary Level. Voluntary odd/even watering and no week-end watering. The ending number of your house address determines odd or even.
  • Level 1 - Water Restriction. Mandatory odd/even watering and no week-end watering.
  • Level 2 - Water Emergency. No outside watering.
Non-compliance may result in a fine of up to $200.00 per violation.

It is necessary that the district have the required water pressure for an emergency.

Watch district signs for restrictions. The four district signs are located on: Mason Road by the ditch, Highland Knolls by Randall's, Westgreen by the ditch and the elevated tank by the junior high.

Water Consumption

Water facts:
  • More than 339 billion gallons of water are used in the U.S. every day.
  • Americans drink more than one billion glasses of water a day, the 94 million gallons a day saved could be provide water for one year to Baltimore, MD.
  • On average, 50-70 percent of household water is used on lawns and gardens.
HC MUD 81 has four water wells. One of the wells has an elevated tank. HC MUD 81 pumps an average of 40 million gallons of water per month. On July 16, 2000, 3 million, 400 thousand (3,400,000 gallons of water) were pumped!!! More water is consumed on the week-ends than at other times with the heaviest usage on Sunday evenings between 4:00 p.m. and 10:00 p.m. to help avoid water rationing, residents are asked not to water their yards on Sunday evenings between 4:00 p.m. and 10:00 p.m. not even with a hand-held hose!!!!

Water Conservation

To conserve water and keep water bills low, the District recommends:
  • Fix pipe leaks, install low-flow faucets and shower heads, and toilets that use less than 2 gallons per flush.
  • Fix toilet leaks.
  • Do not leave the water running when you brush your teeth or shave.
  • Plant grass, flowers that require minimal watering.

Swimming Pools, Spas, Hot Tubs, Sprinklers

State of Texas regulations require that inspections be conducted on new and existing backflow prevention devices. Pools in and above ground, spas, hot tubs and sprinkler systems must have testable backflow prevention devices. They must be tested when they are installed and then yearly by a recognized backflow prevention assembly tester. Residents who already have pools, spas, hot tubs and sprinklers must have a testable back flow prevention device and must have them inspected. A list of certified backflow prevention assembly inspectors can be obtained from the local office of the Texas Commission on Environmental Quality. There will be a $100 annual administrative cost for locations with backflow prevention devices of $100, which is due and payable upon notification. Backflow prevention devices are very important to protect the quality of the drinking water in the district. Failure to have any required inspection may result in termination of your water service. Swimming pools, both above and in ground, must drain to the sanitary system, not to the storm sewer system.

Harris Galveston Subsidence District and West Harris County Regional Water Authority

Harris County MUD 81 is within the boundaries of the Harris Galveston Subsidence District (the Subsidence District), which regulates groundwater withdrawal. The Subsidence District has adopted regulations requiring reduction of groundwater withdrawals through conversion to alternate source water (e.g., surface water) in certain areas within the Subsidence District's jurisdiction, including the land within Harris County MUD 81. The Subsidence District imposes disincentive fee penalties, currently $9.80 per 1,000 gallons of water, for groundwater use that exceeds its regulations.

For more information about the Subsidence District, please visit:

In 2001, the Texas legislature created the West Harris County Regional Water Authority (the Authority) to, among other things, reduce groundwater usage in, and to provide surface water to, the western portion of Harris County and a small portion of Fort Bend County. Harris County MUD 81 is located within the boundaries of the Authority. The Authority has entered into a Water Supply Contract with the City of Houston to obtain treated surface water from Houston. The Authority has developed a groundwater reduction plan (GRP) and obtained Subsidence District approval of its GRP. The Authority's GRP sets forth the Authority's plan to comply with the Subsidence District regulations, construct surface water facilities, and convert users from groundwater to alternate source water (e.g., surface water). Harris County MUD 81 has not yet been converted to alternate source water, but instead currently pays pumpage fees to the Authority in the amount of $3.70 per 1,000 gallons of groundwater pumped.
