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.
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
- 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.
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 back flow prevention devices. Pools in and above ground, spas,
hot tubs and sprinkler systems must have testable back flow prevention devices. They
must be tested when they are installed and then yearly. Residents who already have
pools, spas, hot tubs and sprinklers must have a testable back flow prevention device
and must have them inspected. The cost of $50.00 for residential, $125.00
non-residential per trip for the inspection will be added to your water bill. To
schedule an inspection, call 281-290-6503 and ask for the inspection department. These
devices are very important to protect the quality of the drinking water in the district.
Failure to have the inspection may result in termination of your water service. Swimming
pools, both above and in ground, must drain to the sanitary 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
$8.75 per 1,000 gallons of water, for groundwater use that exceeds its regulations.

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 $2.95 per 1,000 gallons of groundwater pumped. The Authority has proposed
to increase the pumpage fees by $0.25, to $3.20 per 1,000 gallons of groundwater pumped,
effective January 1, 2020.
