Tomball, Harris County
The Plumber Tomball TX Households Call Is Working Inside a Town Whose Drought Rules Are Set by Its Own Water Meters
Most places declare a watering restriction because it has not rained, or because a regional authority told them to. Tomball does not. Its adopted Water Conservation and Drought Contingency Plan sets five stages on a single measurement, and that measurement is how much water its own customers used against how much its own plant can make.
Stage 1 fires when consumption exceeds sixty per cent of production capacity for three consecutive days. Stage 2 at seventy, Stage 3 at eighty, Stage 4 at ninety, Stage 5 at ninety five or on a system outage or a contamination event. The city moved to Stage 1 on 28 July 2026.
Read that as a plumber and it says something no other page on this site can say. In Tomball a leak is not only a bill. It is an input to a legal trigger, in a water system with roughly four thousand eight hundred meters on it, where the difference between voluntary and mandatory is ten percentage points of demand.
The Lead Fact
A Drought Stage Here Is an Arithmetic Result, Not a Weather Report
The city publishes its stages and its triggers side by side, which is unusual in itself. Most drought plans describe what you may not do. This one also shows you the number that decides it.
| Stage | Trigger the city publishes | Restrictions |
|---|---|---|
| Stage 1, Mild Drought Condition | Water consumption exceeds 60 per cent of production capacity for three consecutive days | Voluntary |
| Stage 2, Moderate Drought Condition | Water consumption exceeds 70 per cent of production capacity for three consecutive days | Mandatory |
| Stage 3, Severe Drought Condition | Water consumption exceeds 80 per cent of production capacity for three consecutive days | Mandatory |
| Stage 4, Critical Drought Condition | Water consumption exceeds 90 per cent of production capacity for three consecutive days | Mandatory |
| Stage 5, Emergency Water Condition | Consumption exceeds 95 per cent for three consecutive days, or system outages, or contamination of water supply | Mandatory |
Two features of that table matter to anybody with a dripping fitting. The first is that demand is the whole variable at four of the five rungs. The second is the three consecutive days, which is what turns a leak from an event into an input: a single hot Saturday does not move the stage, and a fortnight of quiet unrepaired losses across a few hundred properties plausibly does.
The city stated the reason for its 28 July 2026 declaration in those terms. It implemented Stage 1 Mild Drought Contingency due to increased water demand in conjunction with continued dry conditions. Demand is named first.
The same summer, the same problem, a completely different authority
We published our Spring Hill, Florida page a day before this one, and the contrast is worth setting out because it changes what a household can usefully do. Hernando County is under a Modified Phase III extreme water shortage declared on 30 March 2026 by the Southwest Florida Water Management District, a regional regulator, across a whole district, in response to drought conditions. Nothing a single Spring Hill household does moves that order.
Tomball declared its own stage four months later off its own meter readings against its own plant. That is a much smaller loop and the household sits inside it. Fixing a leak in Spring Hill saves you money. Fixing a leak in Tomball saves you money and is a small part of what decides whether the town is watering on two days a week or none.
The Second Fact
Three of Your Four Utilities Are the Same Organisation, and Out of Hours They Are the Same Phone Call
Inside the city limits, Tomball owns and operates the water system, the wastewater system and the natural gas system. It publishes the same daytime number for a failure in any of them, (281) 290-1400, and the same after hours number for all of them, (281) 351-5451.
That second number is the Tomball Police Department non emergency line. The city says so plainly and explains why: call it on nights, weekends and holidays so that a call duty technician can be dispatched to your location. There is no separate twenty four hour utility call centre here, and none is needed, because the dispatch function already exists and runs all night.
The practical consequence is one most households never think about until they are standing in the dark. In a normal city the first job at two in the morning is diagnosis: is this gas or is it a drain, is this my water or the main, and therefore who do I ring. Getting that wrong costs you the call. In Tomball the diagnosis can wait, because all three routes converge.
The exception is gas, and the exception is about sequence rather than about the number. The city is explicit. On a strong gas odour, leave the house immediately, do not make calls from inside because a phone can produce a spark, do not light anything, do not turn switches on or off and do not plug or unplug an appliance. Then call, from a phone outside. Get out first, dial second.
The Sort Nobody Runs
What the City Owns, What It Only Relays, and What It Sends You Away For
Sort a small city by department and you learn its org chart. Sort it by whether it can actually fix the thing you are ringing about and you learn something more useful, because Tomball sits in three different relationships with the six services a household treats as interchangeable.
Owns it: water
The city runs the drinking water system, tests and treats it, and systematically flushes distribution lines. It is recognised by the Texas Commission on Environmental Quality as a Superior Public Water System and has a Water Fluoridation Quality Award from the Centers for Disease Control and Prevention. It confirms in its own FAQ that the water is fluoridated.
Owns it: wastewater
Treatment plants on the north and south sides, eleven lift stations maintained by Public Works, and a collection system serving 2,894 households not counting apartments. One utilities superintendent for the lot.
Owns it: natural gas
The city owns and operates the gas system inside the city limits, adds the mercaptan that gives it its smell, and marks its own buried gas lines with yellow stakes, flags or paint after Texas 811 notifies it. Forty eight hours notice, no charge.
Relays it: traffic signals
The city states it does not repair or maintain traffic signals, which belong to the Texas Department of Transportation and Harris County Precinct 4, but tells you to call it anyway and it will report the issue on your behalf. A relay is not ownership and it is not nothing.
Sends you away: electricity
The city states plainly that it does not furnish electrical services and points at the Texas retail market to find a provider. Street light outages go to CenterPoint directly. This is the one utility where you are on your own for the phone number as well as the fault.
Sends you away: hazardous waste
No city facility for household hazardous waste. Harris County runs one, by appointment only. Worth knowing before a repipe leaves you with old solvent, flux and half a can of something you should not pour down a drain that the city does own.
Card five is the one that catches people during a plumbing failure, because electricity and water fail together more often than either fails alone. A storm that takes your power has also taken the power to eleven lift stations, and the city that will answer the phone about the sewage is not the organisation that can tell you when the lights come back.
The Test That Comes First
Before Any of the Above Applies, Check Whether You Are Actually in Tomball
The city answers this question itself, and the answer is no. A Tomball mailing address does not always mean the property is inside Tomball city limits. Some Tomball addresses are in unincorporated Harris County.
It also publishes the test. Check the property on the Harris County Appraisal District website and look at its taxing entities. If the list includes the City of Tomball, the address is within city limits. The city offers its own online map for the same purpose.
That single check decides an enormous amount. Inside, your water, sewer and gas are all the city, your permit and your inspector are the city, and the drought stage on this page is your drought stage. Outside, your water almost certainly comes from a municipal utility district or a regional authority, your permitting runs through Harris County, and the city drought plan does not reach you. Our Spring page covers that side of the line in detail, because unincorporated north Harris County is a genuinely different regulatory world with its own water authority, and our Katy page covers the same problem on the west side of the county.
Get this wrong and you can be quoted against the wrong rulebook entirely. A contractor quoting a city permit path for a property that turns out to be in the county is not necessarily being dishonest, but somebody has to notice, and the appraisal district lookup is the cheapest way for that somebody to be you.
Where the Line Falls
The Bluntest Sentence About Ownership on Any City Website We Have Read
Most utilities describe the meter as a boundary. Tomball describes it as a transaction. Every customer has a water meter that separates the city water system from their private plumbing system, and once the water passes through the meter, the customer has purchased it.
That framing is worth sitting with, because it quietly answers a question households ask every time a bill spikes. A leak on your side of the meter is not a fault in a service you were being provided. It is water you bought and then lost. There is no defect to complain about, which is why an adjustment, where one exists at all, is a discretion rather than a right.
The same page explains the money behind it. The water, sewer and natural gas systems are set up as a self supporting utility, so all of the money received from water and sewer bills pays the operating costs for the system, and water and sewer payments do not fund any other service the city provides. A ring fenced enterprise fund has no general budget to absorb losses from.
The meter itself is currently changing. The city is replacing all manual read and ageing residential and commercial meters, roughly 4,800 of them, with advanced metering infrastructure, working with a contractor called Aqua-Metric over an expected twelve months. The new meters carry a low powered radio that records usage continuously and transmits a reading every six to twelve hours.
Before You Book Anybody
Six Things Worth Knowing About a Tomball Job Before the Van Arrives
None of these change the plumbing. All six change the timing, the phone number or who is allowed to be standing on your property.
- Which side of the city line the property sits onCheck the appraisal district taxing entities first. It decides your utility, your permit office, your inspector and whether the city drought stage applies to you at all.
- Whether work is planned in the watering windowRegardless of assigned days, irrigation systems and hose end sprinklers are prohibited between 5 a.m. and 7 p.m., and a bucket or watering can may be used at any time. Flushing and testing plans should be built around that rather than into it.
- Whether your meter has already been swappedThe city says crews leave a door hanger once a new meter is set, carrying instructions on flushing your lines. If you have discoloured water or air in the taps shortly after a swap, that hanger is the first thing to look for.
- Who is actually at the doorCity employees and the Aqua-Metric contractor carry identification and safety gear, city crews accompany the contractor most of the time, and neither needs to come inside your home at any point. The city publishes a customer service number to check on (281) 290-1450.
- Whether the job needs 811 firstThe city marks its own buried gas lines with yellow stakes, flags or spray paint after Texas 811 notifies it, and it asks for the request 48 hours in advance. The service is free. In a town where the gas utility is also the permit office, that call is not a formality.
- When the bill is dueUtility bills are due by 4 p.m. on the last business day of the month to avoid a late penalty. A late afternoon deadline on a shifting date is easier to miss than a fixed calendar day.
The watering item is the one that surprises trades rather than households. Pressure testing a new irrigation zone, flushing a repipe or filling a pool are all daytime jobs by habit, and the prohibited window here runs from five in the morning to seven at night. There is a formal way out: the city takes petitions for variance, filed within five days after the plan or a particular response stage has been implemented, through Public Works. Five days is a narrow door and it opens when the stage changes, not when your job is scheduled.
Permits and Paperwork
Where the Building Office Sits in All of This
Inside the city limits, plumbing work goes through the City of Tomball Building Division at 501 James Street. The office is open 8 a.m. to 5 p.m. Monday to Thursday and 7.45 a.m. to 4 p.m. on Fridays, which is a small detail worth noticing because the Friday day both starts earlier and ends an hour sooner.
Permit applications and plan submittals run through the city SmartGov portal, and inspections are requested through the same route. The city lists the code families it works from, and the International Plumbing Code is named among them alongside the building, mechanical and residential codes. A master fee schedule is published for the current financial year.
We are not quoting a permit fee, a water rate or a gas rate anywhere on this page, and the reason is worth stating rather than hiding. The city rate document is a scanned image and our text extraction returns nothing from it at all. Guessing at a figure we could not read would be worse than leaving the gap, so the gap is left and named.
One rule that does affect scheduling more than most people expect is the drought schedule above. It tightens by taking days away rather than by shortening the evening window, so a job that needs an irrigation system charged and run is a job that needs a specific day of the week as much as a specific hour. At Stage 5 there is no day at all.
Where We Work
Tomball and the Ground Around It
Tomball is a small incorporated city in north west Harris County, surrounded on most sides by unincorporated county and by the master planned developments that have grown out to meet it. The names below are the ones people give us when they book, and several of them are on the other side of the city line.
Three of those are the traps. Magnolia and Pinehurst are separate incorporated cities with their own governments, and Magnolia is in a different county entirely. Northpointe, Rosehill, Decker Prairie and Klein are unincorporated, which means county permitting and a utility district rather than the city, and our Spring page is the one that covers how that world works. For the wider county picture, including the ground movement problem that shapes everything here, see our Houston page.
The list is geography rather than a coverage promise, and in this particular city it is not even a reliable guide to jurisdiction, because the boundary is irregular and changes with annexation. The appraisal district lookup above settles it for a specific address in a way that no neighbourhood name can.
What We Do Here
The Work That Actually Comes Up in Tomball
A small city that owns its own gas, its own water and its own sewer, sitting on flat Gulf coastal plain, produces a slightly different mix of jobs from its unincorporated neighbours.
Leak detection
The single most consequential job in a town whose drought ladder is built out of measured consumption. Finding a loss here saves the bill and takes a small amount of pressure off the trigger. See leak detection.
Gas line work
Unusual here because the utility, the locator and the permit office are the same organisation. Texas 811 notifies the city and the city marks its own lines. See gas line services.
Sewer line repair
Flat ground, a pumped collection system and a lot of mature trees along the older streets in and around Old Town. See sewer line repair.
Drain cleaning
One of the larger families of search terms in this city after the plain trade term, which usually points at fixture branches and long horizontal runs rather than one dramatic failure. See drain cleaning.
What we will not do is tell you which utility district serves an address outside the city limits. That answer comes from the district or the authority, not from us and not from the city, and getting it wrong is the most common way a north Harris County plumbing conversation goes off the rails in the first five minutes.
Tomball Plumbing Questions, Answered From What the City Publishes
Every answer below is taken from City of Tomball published pages. Drought stages move with measured demand and can change in days rather than seasons, so confirm the current stage and the current contact numbers before anything depends on them.
The city said yes as of 28 July 2026, when it implemented Stage 1 Mild Drought Contingency and asked for voluntary conservation. What matters more than the answer is how the answer is produced. Tomball’s stages are triggered by water consumption exceeding 60, 70, 80, 90 and 95 per cent of production capacity for three consecutive days, with Stage 5 also triggered by system outages or contamination. Because stages move with measured demand rather than with rainfall, the current stage can change quickly in both directions. Check the city drought status page rather than relying on this one.
Under the current Stage 1 schedule the city asks for watering only between 7 p.m. and 5 a.m. on designated days. Odd numbered addresses, ending in 1, 3, 5, 7 or 9, water on Wednesdays and Saturdays. Even numbered addresses, ending in 0, 2, 4, 6 or 8, water on Thursdays and Sundays. Regardless of assigned days, watering with an irrigation system or a hose end sprinkler is prohibited between 5 a.m. and 7 p.m., and a bucket or watering can may be used at any time. At Stages 2 and 3 the two days become one, and at Stage 5 irrigation is prohibited entirely.
The same number for all three. In normal business hours it is (281) 290-1400. On nights, weekends and holidays it is (281) 351-5451, which is the Tomball Police Department non emergency line, and the city explains that calling it gets a call duty technician dispatched to your location. The city owns and operates the water, wastewater and natural gas systems inside the city limits, which is why one route covers all of them. It does not supply electricity.
The city is specific and the order matters. Leave the house immediately. Do not make calls from inside your home, because phones can produce a spark that could start a fire or trigger an explosion. Do not light a match or any combustible material, do not turn switches on or off, and do not plug in or unplug an appliance. From a phone outside the home, call the city on (281) 290-1400 in business hours or (281) 351-5451 at nights, weekends and holidays. The smell itself is deliberate: the city adds mercaptan so that a colourless, odourless gas is detectable by your nose.
Not necessarily, and the city answers this itself. A Tomball mailing address does not always mean the property is inside Tomball city limits, and some Tomball addresses sit in unincorporated Harris County. To check, look the property up on the Harris County Appraisal District website and read its taxing entities. If the City of Tomball is listed, you are inside. The city also publishes an online map for the same question. This one check decides your utility, your permit office, your inspector and whether the drought stage applies to you.
The city describes the meter as the point of sale rather than as a boundary. Every customer has a water meter that separates the city water system from their private plumbing system, and once the water passes through the meter, the customer has purchased it. So a loss on your side is water you bought and did not use, and the commonest quiet causes are a running toilet and an irrigation line that leaks while the system is off. The city also runs its water, sewer and gas as a self supporting utility, meaning those bills fund only that system.
The city is replacing roughly 4,800 manual read and ageing meters with advanced metering infrastructure, working with a contractor called Aqua-Metric, over an expected twelve months. Customers are not charged for the meter or the installation. A typical swap takes under 30 minutes with about 15 minutes without water. Nobody needs to enter your home. Crews leave a door hanger when the new meter is set, with instructions on flushing your lines, and the new meter reports a reading by radio every six to twelve hours.
No, and it says so directly, pointing residents at the Texas retail electricity market to choose a provider. Street light outages are reported to CenterPoint rather than to the city. Traffic signals belong to the Texas Department of Transportation and Harris County Precinct 4, though the city will take your call and report the fault for you. The city also has no household hazardous waste facility, and points at the Harris County facility, which is appointment only.
Yes, and unusually there is nowhere else it could be about. Tomball is a unique place name in the United States, and we measured that rather than assuming it: across the whole search corpus, not one query containing the word Tomball names any state other than Texas. That is rare on this site, where most city names are shared by five or ten states, and it is the reason the demand figures for this city need no correction at all.
Sources, Refusals and Caveats
What This Page Refused to Say, and Why
Every rate, and the reason is a scanner rather than a judgement
No water, sewer, gas or permit figure appears anywhere on this page. The city utility rate document is a scanned image of about 1.3 megabytes and our text extraction returns literally zero characters from it. The same is true of the 2024 water quality report, which is a four page image based newsletter, so no hardness figure and no source aquifer is given either. An unreadable document is not permission to estimate.
The lift station arithmetic was available and was deliberately left alone
The city publishes eleven lift stations and a collection system serving 2,894 households, which is roughly one pump per two hundred and sixty homes, and its own explainer draws the line from a pumping station failure to a sewer backup. Pumped collection systems are a well worked subject across this site, including a Florida city with about a hundred and sixty five lift stations and an Illinois village whose fourteen make the same point. The counts appear here once, as scale, and nothing is built on them.
One ambiguity, printed rather than resolved
The city sentence describing its wastewater treatment plants can be read two ways. It says the city has 1.5 million gallons per day wastewater treatment plants on the north and south sides, which is either 1.5 million gallons per day each or 1.5 million between them. We are not guessing, so no total plant capacity is stated on this page.
What sits outside the city line, and where it is covered instead
Nothing on this page describes the municipal utility districts, the regional water authority or the county permitting route that govern unincorporated north Harris County, because our Spring page already covers that ground in detail and our Katy page covers the equivalent structure on the west side. Backflow prevention is refused without being opened, as a closed subject across this site.
We found no contradiction between the city own pages on this run, which is recorded rather than assumed. On measurement, this is the only city in this batch whose name is unique in the United States. Every query in the search corpus containing the word Tomball sits in Texas, and not one names another state, so no correction to the demand figures was needed in either direction.
Start with the city drought status page for the current stage and the watering schedule, and its natural gas page for the leak response and the line marking process. For work on your side of the meter, see our leak detection page or get in touch.
Everything above was read from City of Tomball published pages at the time of writing. Drought stages here are driven by measured demand and can move within days, contact numbers and office hours are revised, and city limits change with annexation. Nothing here is a quotation of record, a legal opinion or a substitute for calling the department that owns the answer.
