Revised Stage 2 Mandatory Water Conservation

Fort Bend County MUD 48 (FB48) revised its Drought Contingency Plan (DCP) on September 14, 2023 to follow that of Missouri City’s (the City) DCP.

This REVISED Stage 2 Notice is updated to reflect those changes. To view the FB48 DCP, visit To view the City Water Conservation information, visit

Due to worsening drought conditions, on August 28, 2023, the City of Missouri City implemented mandatory water conservation in some areas of the City INCLUDING FB48 which is within the City’s Mustang Bayou Service Area. These measures were put into effect because water systems are not able to keep up with high demand especially during the “Peak Demand” times in the early morning hours when most irrigation occurs and as residents take showers, wash laundry, and prepare meals. Irrigation usage is the largest user of water. The Ground Storage Tanks (GSTs) at the water plants need to maintain water sufficient to fight fires and to provide potable drinking water to customers.

You can view the Map of Affected Areas (PDF) here: Blue indicates mandatory conservation. Yellow indicates voluntary conservation.

ALL outdoor water usage, including, but not limited to, lawn and garden watering, car washing, and window washing, shall be limited as follows:

Prepare for the Freeze

Protect Your Pipes

Freezing conditions are expected this Thursday evening with low temperatures near below freezing. Be sure to protect your pipes!

Why Pipe Freezing is a Problem – Water expands as it freezes and pipes that freeze most frequently are those that are exposed to severe cold, like outdoor hose bibs, swimming pool supply lines, water sprinkler lines, and water supply pipes in unheated interior areas like attics, garages or kitchen cabinets. Pipes that run against exterior walls that have little or no insulation are also subject to freezing.

How To Prevent Your Pipes From Freezing
  • Drain water from swimming pool and water sprinkler supply lines following manufacturer’s or installer’s directions.
  • Remove, drain, and carefully store all hoses that are used outdoors.
  • Both hot and cold-water pipes in unheated areas should be insulated. A hot water supply line can freeze just as easily as a cold-water supply.
  • Consider installing specific products made to insulate water pipes like a “pipe sleeve” or installing UL-listed “heat tape”, “heat cable” or similar materials on exposed or susceptible to freezing water pipes.
  • When the weather is very cold outside, let the cold and hot water drip from the faucet served by pipes that are susceptible to freezing. Running water through the pipe – even at a trickle – helps prevent pipes from freezing because the temperature of the water running through them is above freezing.

If you suspect that the plumbing may be frozen at the point where the pipe goes under the house or in the attic, it is safest to call a plumber as it may be cracked and burst when thawed.

In the event of an emergency, please contact our operator, Municipal District Services, at 281-290-6500. Water running in the street or buckled pavement are signs of a water main break and should be reported immediately.
