Water softeners & filtration in Missouri City
Much of Missouri City is served by MUDs that blend local groundwater with surface water from the City's Regional Water Treatment Plant.
What public reports say about Missouri City water
- The City's Regional Water Treatment Plant treats Brazos River water, delivered through the Gulf Coast Water Authority's Briscoe Canal, with membrane filtration, and supplies participating MUDs.
- The plant disinfects with chloramine. The 2024 South Service Area report lists an average chloramine residual of 2.48 ppm, under the 4 ppm limit.
- Some service areas, such as Mustang Bayou, are listed as groundwater only, so water differs across the city.
Water varies by home, utility and MUD. Figures come from the public reports linked below.

Missouri City water questions
Where does Missouri City’s water come from?
It depends on your service area. The South Service Area report lists groundwater from Sienna MUD 1 plus Brazos River surface water from the City. Mustang Bayou is listed as groundwater only.
Does Missouri City use chloramine?
The Regional Water Treatment Plant disinfects with chloramine, and the 2024 South Service Area report lists an average of 2.48 ppm.
How hard is Missouri City water?
The City’s reports don’t publish a single hardness figure. A mailed water test checks your home’s actual hardness.
How much do systems cost?
The Water Softener starts at $2,589. A standalone under-sink RO is $795, and the RO add-on is $595. Essentials, Softener + Carbon, Softener + Carbon + RO, and Premium are tiers quoted after your free mailed water test. A written proposal after your water test confirms the price for your home. You pay 30% when you approve the proposal (that orders your system, which ships to your home) and the remaining 70% after it is installed and working. From Nov 18, 2026 to Jan 31, 2027, get $150 off the Softener + Carbon + RO package or the Premium Whole-Home package. The offer does not apply to other packages.
How long does installation take?
After you approve the written proposal, a 30% deposit orders your system, which ships to your home. A licensed installer then does a quick on-site reading to confirm your numbers and installs the system. We will give you a scheduled install date once the equipment is on the way. Call (832) 639-4127 if you want to talk through what to expect for your package.
Do I have to add salt?
Yes, if you choose a salt-based softener. It uses salt to remove hardness minerals (calcium and magnesium), and you add salt to the brine tank periodically. A salt-free conditioner does not remove hardness the same way, so a hardness test still reads hard. We recommend a system after your mailed water test.
Is financing available?
Financing available, subject to approval. See our financing page. We do not publish rates on this page.
How much is the water test?
The mailed water test is free. Booking takes a $20 deposit, credited toward your system when installed; it is non-refundable if you choose not to install. There is no obligation to buy a system.
