If you searched "The Woodlands water," you might just need the utility. That is Woodlands Water, at 855-426-7283, with its office on Lake Robbins Drive. Its website has a "Find Your MUD" page if you are not sure which district you are in.
If you want to know what is in the water, I read the 2025 water quality reports for every district Woodlands Water serves. Here is what they say, in plain terms.
Already know you want better water?
Call me or send the form, tell me what you are noticing at the tap, and I will walk you through the systems that fit and what they cost.
Who supplies water in The Woodlands
Woodlands Water serves ten municipal utility districts, or MUDs, the local districts that deliver water to each neighborhood. The ten are The Woodlands MUD No. 1, Montgomery County MUDs No. 6, 7, 36, 39, 46, 47, 60 and 67, and The Woodlands Metro Center MUD.
Each one publishes its own yearly report, called a Consumer Confidence Report. All ten say the same thing about the source: they buy a mix of groundwater and surface water from the San Jacinto River Authority's Woodlands Division.
Lake Conroe water and deep wells, blended
The reports describe two sources. The first is groundwater: 38 wells feeding five water plants, pumping from the Evangeline and Jasper aquifers from as deep as 1,700 feet.
The second is Lake Conroe. Its water is treated at the river authority's surface water plant, which the authority rates at 30 million gallons a day, then sent to the Woodlands Division plants and blended with the well water.
How much of each? The river authority's April 2026 operations report shows an even split for fiscal year 2025: 50% groundwater and 50% surface water. For the first part of fiscal 2026 it was 52% groundwater and 48% surface water.
The disinfectant is free chlorine, not chloramine
This is the line I would point out first. All ten 2025 reports list free chlorine as the disinfectant, with yearly averages between 1.73 and 2.05 mg/L. The highest level allowed is 4.
That is different from the City of Houston, which uses chloramine and averaged 2.8 ppm in its 2025 report.
Either way, if the tap smells like a pool, carbon filtration is what reduces that taste and smell. A whole-home filtration system puts the carbon where water enters the house, so the shower, the laundry and the ice maker all get it.
Hardness: the number these reports leave out
One thing to know: none of the ten 2025 reports lists a hardness number. I am not going to borrow one from a sales website and pass it off as yours.
What I can tell you is what hard water looks like: white crust on shower heads, spots on glasses, and soap that does not rinse clean. The U.S. Geological Survey says scale from heated hard water can shorten the life of a water heater and raise the cost of heating water. If you are seeing those signs, a water softener is the system that takes the hardness minerals out. If you want the number, call Woodlands Water and ask for it.
Seeing scale and spots?
Tell me what you are noticing and I will walk you through the softener and filtration options that fit your house, with one honest, upfront price.
Other lines worth knowing
- Lead, measured at customer taps: each district reports a 90th percentile result, the level 90% of its samples fell below. Across the ten, those ran from 0.634 to 3.32 parts per billion (ppb), against an action level of 15. One sampling site in MUD 67 tested above 15 in its 2022 to 2024 round.
- Disinfection byproducts, chemicals the reports list as a by-product of disinfecting the water: the highest yearly average was 70 ppb for total trihalomethanes in MUD 67 (limit 80), and 21 ppb for haloacetic acids in MUD 7 (limit 60).
- MUD 7 lists one violation: it did not complete required lead and copper tap monitoring for 2023 to 2025. That is a missed sampling requirement, not a high reading.
Every report says lead comes mainly from service lines and home plumbing, which the district cannot control, and that a filter certified to reduce lead is effective at reducing exposure.
Which systems fit a home in The Woodlands
- Whole-home filtration for the chlorine taste and smell at every tap.
- A water softener for scale, spots and soap film. It pairs with filtration as one system.
- Reverse osmosis under the kitchen sink, for drinking and cooking water from its own faucet. If lead is your reason, ask me what the unit is certified to reduce.
- And if your tank water heater is near the end of its life, I install tankless water heaters too.
Not in The Woodlands?
Everything above is for the ten Woodlands Water districts. Tomball and Cypress are not on the Woodlands Water list, and I have not read their suppliers' reports yet, so I will not guess at their numbers. Your water bill names who supplies you. I work in both, so call me with what you are seeing.
