The Woodlands city guide

Local Utility and Treatment Research

The research below preserves city-specific utility distinctions, evidence limits, testing guidance, and proposal questions.

Quick answer: The Woodlands is served by eleven district water systems, not one. Ten municipal utility districts managed by Woodlands Water cover the Montgomery County side, and Harris-Montgomery Counties MUD No. 386 serves parts of Creekside Park in Harris County. Find your district on the water bill, read its current report, and test at the tap before choosing a softener or filter. The companies below name The Woodlands on their own websites; their service statements were re-checked on October 24, 2026.

The company list on this page comes from the Houston-area directory. Each company was checked against its own website on October 18, 2026, and the service statements for the companies listed here were opened again on October 24, 2026. Each service tag links to the page that states it. A listing is not a booking and does not confirm service at your address.

Find the district serving your Woodlands address

  1. Check the district name on a recent water bill, or use The Woodlands Township utilities page and district map.
  2. Open that district's report from the Woodlands Water report hub (or MUD 386 for Creekside Park).
  3. Look the system up in the TCEQ Drinking Water Watch for sampling history.
  4. Private wells need their own water testing plan.

What the 2025 district reports show

These ranges span all eleven district reports. They help you know what to look for in your own district's report. They are not a Woodlands average.

Measure Range across districts What it means for treatment
Free chlorine residual 1.46 to 2.05 mg/L The districts report chlorine. A carbon whole-house filter with a chlorine taste and odor claim targets this.
TTHM (disinfection byproduct) 5.3 to 70 ppb Highest 2025 running annual average by district (MUD 386 reports highest detected). The federal limit is 80 ppb.
HAA5 Not detected to 21 ppb Highest 2025 running annual average by district. The federal limit is 60 ppb.
Lead, 90th percentile 0.634 to 3.32 ppb Monitoring periods vary. MUD 67 also reported one sampled site over the 15 ppb action level.

District-level details, including a monitoring violation reported by MUD 7 and wholesale supply for MUD 386, are on The Woodlands water quality by district. The district results summarized here do not include one hardness figure for The Woodlands, so measure hardness at the tap before sizing a softener.

Match the concern to the right system

  • Scale and spotting point to hardness. Measure it at the tap, then size a water softener from the measured hardness, household size and peak flow. The water softener size guide shows the math.
  • Chlorine or chloramine taste and odor across the house call for a whole-house filtration system with a published claim for the disinfectant your utility uses.
  • Drinking and cooking water at one tap is the job of reverse osmosis, usually under the kitchen sink. Check the certified claims for the exact model.
  • A question the report can't answer needs water testing at the property, matched to the decision you are making.

Using The Woodlands company list

None of the companies in our directory is based in The Woodlands, so this list shows Houston-area companies whose own website or published coverage names The Woodlands, alphabetically. This site does not publish ratings, rankings, prices or license claims. Ask each company for its Texas water treatment specialist license number and look it up with the TCEQ, and get the exact model, certification and written scope before you compare quotes.
