The MUD Rate Notice in Your Mailbox — and How to Actually Read It

If you bought a house in one of the subdivisions that have filled in along FM 1488 over the last fifteen years, there is a decent chance your water does not come from the City of Magnolia. It comes from a Municipal Utility District — a MUD — a unit of local government most people have never knowingly voted in, run by a board most people could not name, that sets two of the numbers on your household ledger: the rate you pay per thousand gallons, and a slice of your annual property-tax bill.

Not a scandal. It is how Texas finances the water and sewer lines under new neighborhoods. But it means a small board you have probably never met has real authority over your monthly cost of living, and the notices that board mails you are the only routine window into what it is doing. Reading them is the whole game.

First: what a MUD actually is

A Municipal Utility District is a special-purpose local government created to build and run the water, sewer, and drainage infrastructure for a defined patch of land — usually a new development outside an existing city's utility system. To pay for the pipes, the district sells bonds. To pay the bonds back, it levies a property tax on the homes inside the district. To keep the system running day to day, it charges you for the water and sewer you use. Its board of directors is elected by residents, and that board sets the rates. Magnolia's first in-city MUD, Magnolia MUD No. 108, was approved by the City Council in January 2016 to serve roughly 550 acres along FM 1488 — a marker of how the model followed the corridor's growth straight inside the city limits.

The two numbers that decide what you pay

Almost everything on a MUD notice resolves into two figures. The first is the water-and-sewer service rate — the operations-and-maintenance, or "O&M," charge — what you pay for the water you actually use, usually a base fee plus a per-thousand-gallons rate that climbs in tiers the more you use. The second is the property-tax rate the district levies. That one splits further: a debt-service rate that retires the bonds that built the system, and a maintenance-and-operations rate that helps keep it running. Early in a district's life the debt-service piece is the heavy one — you are paying down the cost of the build-out. As bonds get paid and rooftops fill in to share the load, it tends to ease.

Where the money goes

Water & sewer service (the O&M rate) what you use

Property-tax rate — debt service (the bonds) the build-out

Property-tax rate — maintenance & operations the upkeep

Proportions illustrate the structure, not any one district's figures. Read your own notice for the dollar amounts.

The "SJRA" line — and a rare bit of good news

If your utility buys into the countywide water program, you will see a line on your bill tied to the San Jacinto River Authority, often labeled an "SJRA fee" or a surface-water or pumpage charge. It exists because of the Groundwater Reduction Plan — a countywide effort to pull less water out of the Gulf Coast Aquifer (the same over-pumping that drives slow ground subsidence under parts of Montgomery County) by piping treated surface water from Lake Conroe to participating utilities. Someone has to pay for that pipe and that treatment. The cost shows up here, as a fee per thousand gallons that your provider passes through to you.

The notable thing about that line right now is that it went down. The SJRA's surface-water rate had risen to $3.41 per thousand gallons, effective September 2022. In August 2024 it was cut to $3.26 per thousand gallons, and the authority also approved a reduction in its wholesale water rate around the same time. In a stretch of years where most utility lines only move one direction, that is worth noting. It is the kind of detail you only catch if you read the notice instead of recycling it.

The SJRA surface-water rate, per 1,000 gallons

Before Sept. 2022 $3.30

Sept. 1, 2022 $3.41

After Aug. 2024 cut $3.26

The part of the notice actually worth reading

This is why the notice gets mailed at all. When a taxing unit — a MUD included — proposes a tax rate above a certain threshold, Texas truth-in-taxation law requires it to tell you, in plain figures, and to hold a public hearing before adopting the rate. The notice lays out the no-new-revenue rate (roughly, the rate that would raise the same money as last year on the same properties), the voter-approval rate (the ceiling above which the district may trigger an election), the proposed rate, and — the line that matters most — the date, time, and place of the public hearing. That hearing is your legally guaranteed chance to stand up before the vote. The notice is an invitation. Most people throw the invitation away.

A four-line checklist

1. 1The proposed tax rate — and how it compares to the no-new-revenue rate. If it's higher, your tax bill on the same house is going up even if the rate "looks" similar.
2. 2The water/sewer rate change — the per-1,000-gallon figure and any tier changes. A new top tier can cost a big household far more than the base rate suggests.
3. 3The SJRA / surface-water line — the pass-through fee, and whether it moved. Right now the countywide rate is $3.26 per 1,000 gallons, down from $3.41.
4. 4The public-hearing date, time, and place — the line that turns the notice from information into an invitation. Put it on the calendar.

Don't assume — read yours

It would be easy to take the SJRA cut and conclude water is getting cheaper. It would also be wrong. Across Montgomery County, a number of MUDs raised their own water and sewer rates in 2025 as they absorbed rising costs and serviced bonds behind fast-growing subdivisions. A district early in its build-out, carrying heavy bond debt against relatively few rooftops, can charge meaningfully more than an older, paid-down one next door. One pass-through fee fell; plenty of individual district rates did not. The answer is never "rates are up" or "rates are down" in general. The answer is on your notice, for your district.

So when the dense single page shows up this summer with "Notice of" across the top, give it five minutes before it hits the recycling. Find the four lines. Note the hearing date. The MUD is one of the few governments that taxes you and is run entirely by your neighbors — which also makes it one of the few where showing up to a half-empty room can genuinely move the number.

Editor's note: We ran this as a straight reader-service explainer rather than a two-view piece because how a MUD is structured and what truth-in-taxation law requires are matters of public record, not contested opinion. Where a specific dollar figure appears — the SJRA rate, MUD 108's founding — it is sourced below. We did not single out any one local district's rate as too high or too low; that judgment belongs to the ratepayers reading their own notice. If your district's notice shows something readers should know about, send it to us.
