Water Shutoff and Flood Zones in Cypress, TX: Who to Call
Cypress has no city water department: homes get water from a Municipal Utility District, and Harris County handles floodplain and permit questions, not a city hall.
Getting the Right Help, In the Right Order
Call 911 only for immediate danger, such as an electrical hazard, a trapped person, or water rising fast enough to threaten the house. For every other water emergency in Cypress, shut off the water at the source, find your MUD or the right Harris County office, contact your insurer, and then reach a restoration provider.
- 911 — when someone is in danger: an electrical hazard, a collapsing structure, or water rising fast.
- Your home's main shut-off valve — stop the source before you do anything else.
- Your Municipal Utility District (MUD) — find the operator on your water bill or in the state's water district database; Cypress has no City water department to call instead.
- Your homeowner's insurer — start a claim after the leak stops and it is safe to photograph the damage.
- A restoration provider serving your area — arrange cleanup once conditions are safe.
This page is general information, not legal or insurance advice — check your own policy and your MUD's own rules for specifics. Renting instead of owning? Put your landlord on notice about the water in writing; your own renters policy protects your belongings inside the unit, not the building itself.

How to Find Your MUD and Shut Off Your Water
Cypress is unincorporated, so no City of Cypress water department exists — a Municipal Utility District supplies water and sewer service to most homes here. Your MUD's name and its own emergency contact are printed on your water bill, and you can confirm the district through a state database if the bill is not on hand.
- Check your monthly water bill or property tax statement for your district's name and its own emergency number.
- Search the Texas Commission on Environmental Quality's Water District Database by address to confirm which MUD serves you.
- Use your home's main shut-off valve if you can reach it safely. Do not force a valve you cannot operate; seek qualified help instead.
Cypress has dozens of separate MUDs, so one district's after-hours number will not reach another. Look up and save your own district's number before you need it, rather than searching for it during a storm.
If a burst pipe or a leak from above has already soaked a wall, floor or ceiling, the Cypress ceiling leak guide covers what to do next while you wait for your MUD or a provider.
Harris County Permits, Drainage and Flooding Questions
Because Cypress has no city government, the Harris County Office of the County Engineer, Permits Division handles building permits, floodplain determinations, and general flooding or drainage questions for the area. One office and one number cover all three, whether you are asking before repairs begin or reporting standing water in a yard.
- General development and building permits: Harris County Permits Division, 713-274-3900.
- An unofficial check of whether your property sits in a flood hazard area: the same Permits Division, same number.
- Flooding and drainage issues on your own property, away from a named creek or bayou: the same office, same number.
Rather than guessing whether your specific repair needs a permit, ask the Permits Division directly before work starts. The Cypress ceiling leak repair guide covers what to check first for damage coming from above.
Channels, Bayous and Creeks: When to Call HCFCD
The Harris County Flood Control District, not the Permits Division, is the number to call when the problem is in a channel, bayou or creek rather than inside your home. Cypress Creek and Little Cypress Creek both run through the area, alongside the northern reaches of the Addicks and Barker reservoir system.
- All channels, bayous and creeks: Harris County Flood Control District, (713) 684-4000.
- This number does not cover water already inside your house, a MUD billing question, or a building permit — use the contacts above for those instead.
Cypress Creek drains a wide, low-gradient watershed with heavy clay soils that slow how quickly rain soaks in, so the creek and its tributaries can rise fast during a heavy storm, according to the Harris County Flood Control District.
Checking Your Flood Zone and Local Flood History
Cypress has flooded more than once in recent years, including during the Tax Day Flood in April 2016 and Hurricane Harvey in August 2017. Neither event tells you whether your specific street sits inside a mapped flood zone — only an address-level map answers that question.
- Harris County Flood Education Mapping Tool — check flood history and drainage detail for your address.
- Harris County Flood Warning System — track rising water on nearby channels and reservoirs.
- TCEQ Water District Database — confirm your MUD at the same time you check flood risk.
Once the water itself is stopped, drying quickly matters — see the Cypress mold after water damage guide for how fast mold can start and what Texas law requires.
If That Did Not Work
If nobody answers on the first call, you still have options. Try the same number again, try a different verified route for the same problem, and know who else to contact if the water issue is urgent or your insurer is not responding to your claim.
- Try again — a second attempt can reach someone when the first one did not.
- Try another route — if your MUD does not answer, check the emergency number printed on your latest water bill; it can differ from the district's daytime office line.
- If calls keep failing, shut off what water you can reach safely, photograph the damage for your insurer, and try the county or your MUD again.
For the bigger picture beyond this page, the Cypress water damage help homepage covers every stage from the first call to the final walkthrough.
