WHY DID MISSOURI CITY ADOPT A JOINT GROUNDWATER REDUCTION PLAN?. A subdivision in Baytown, located in Harris County, has been turned into a park and is now underwater because of the sinking of the land. Why Reduce Groundwater Usage?. To prevent subsidence contributing to : Flooding
A subdivision in Baytown, located in Harris County, has been turned into a park and is now underwater because of the sinking of the land.
To prevent subsidence contributing to:
What is subsidence?
When pumping large amounts of groundwater from underground aquifers, the clay compacts and the elevation of the land surface sinks.
Examples of subsidence in the Greater Houston area
Showing drop in ground elevation
The City of Missouri City, in partnership with other entities, prepared a joint Groundwater Reduction Plan (GRP) to comply with Fort Bend Subsidence District requirements for reduction of groundwater use.
Groundwater and surface water are linked together through the hydrologic cycle
1. Once polluted very hard and expensive to clean 1. Once polluted can be cleaned and fairly inexpensive
2. Sources diminishing 2. Few effects on the environment
3. Adverse effects on the environment 3. Ability to be expanded for larger demand
(for example, subsidence)
The end product will be similar for all drinking water
Groundwater and surface water both have to meet the same
federal and state quality standards for drinking water
The City of Missouri City and its partners will meet the following Subsidence District requirements:
City’s southern portion (Sienna Plantation)
to meet 30 % reduction
approaches in 2025, convert
additional entities, generally moving
northward on the system.

Estimated GRP Plan Savings to Participants:
$1.15 per 1,000 gallons pumped
$11.50 per month for the average home
