A district for both water and sewer
The City of Lakeway says on its own FAQ that it does not manage water or wastewater. Those jobs belong to Lakeway Municipal Utility District, usually shortened to LMUD. It supplies drinking water, collects and treats wastewater and distributes some recycled water. Its customers include most of Lakeway, part of the Village of The Hills and the Rough Hollow area. Since August 2026 it also covers the former Travis County MUDs serving Rough Hollow and The Highlands of Lakeway.
The practical point is that a plumbing question rarely belongs at city hall. A bill with the district’s name on it is the right starting document. Our page on the nearby plumber in The Hills explains the shared boundary.
| Question | Where the answer sits |
|---|---|
| Who supplies my water? | Lakeway MUD in most of town |
| Who takes my sewage? | Lakeway MUD |
| Does the city run either? | No, per the city’s own FAQ |
| Where do I check my account? | The district bill |
What belongs to you
The district owns the mains and the meter. Your side starts at the meter for supply and at the cleanout or property line for the sewer lateral, though exact boundaries vary, so ask the district if a buried failure falls near the line. A leak that makes the meter dial spin with every fixture off is almost always on the house side. Our water line repair page explains how that pipe fails, and the main valve guide shows where to stop it.
- Find the meter boxIt usually sits near the street or driveway edge.
- Close the house valveStops water without touching the district’s equipment.
- Read the meterA moving dial with everything off means a hidden leak.
- Call and report the readingIt saves a diagnostic step.
Lake Travis water, mineral scale and flushing the line
A surface supply with a reported pH
LMUD says its drinking water is drawn from Lake Travis. The 2025 annual report lists a pH of 7.8, which is mildly alkaline and not corrosive on its face. The report also advises running a tap for 30 seconds to 2 minutes when water has sat in the house for several hours. That is useful advice after a weekend away or a night with the house closed up, since the first draw has spent time in your own pipes.
If the water keeps tasting metallic or looks discolored after flushing, call and describe it. It can point to an old fixture, a tired supply pipe or a water heater problem. See signs of corroded pipes for what to compare.
| Item | Detail |
|---|---|
| Source | Lake Travis |
| pH in the 2025 report | 7.8 |
| After water sits for hours | Run the tap 30 seconds to 2 minutes |
| Taste or color still off | Describe it on the call |
Hardness: ask for the figure at your address
The district’s own report does not give a hardness number for the tap. One third-party listing puts Lakeway MUD water near 9 grains per gallon, which sits in the moderately hard to hard band. Treat that as a rough guide and ask the district for a current figure for your street. Scale announces itself anyway: crust at the spout, a clouded glass shower door, a rumbling tank. A water softener addresses the whole house, while water filtration addresses taste and particles at the tap.
Spot the scale
Look at faucet tips, kettles and the shower door.
Ask the district
Request a current hardness figure for your address.
Check the heater
A tank full of sediment loses capacity and gets noisy.
Choose treatment
Whole house for scale, tap-level for taste.
Homes below the street and the backup risk
Why some Lakeway houses are exposed
LMUD has said some homes sit below grade, meaning lower than the sewer main in the street. When the main surcharges or a blockage downstream builds pressure, the lowest opening in the house is where wastewater arrives. That is a basement-level floor drain, a lower bath or a garage sink. The district is installing backflow relief valves at homes where it can, to give that sewage somewhere to stop.
If you see water rise in a tub while the washing machine drains, stop the machine. A sewer camera inspection finds out whether the blockage is in your lateral or the district’s main. Do not pour chemical drain openers into a backing line.
| What you notice | Likely meaning | First move |
|---|---|---|
| Gurgle at a low drain when upstairs runs | Air pushed back by a restriction | Limit water use, then call |
| Water in a floor drain | Line full to a low point | Stop water, keep people away |
| Slow drains in several rooms | Shared branch or main restricted | Call for a camera look |
| One slow sink only | Local clog | Try a plunger, see the guide |
Roots, grease and what you can do
A clog that returns every few months usually has a pattern behind it: grease in a kitchen run, a root intrusion at a joint, or a sag that holds water. Hydro jetting scours a line wall clean, and sewer line repair replaces a damaged section after the camera locates it. The unclog a drain guide covers safe steps for a single fixture.
- Kitchen run slows monthlyGrease on the pipe wall.
- Drain clears, then returnsRoots or a belly in the pipe.
- Everything slow at onceMain line, not a fixture.
- Sewage visibleEvacuate the area and call.
Recycled water, sprinklers and a hilltop lot
Where treated wastewater goes
LMUD treats wastewater at the Palos Verdes Water Recycling Plant and sells the recycled water for irrigation, including golf courses and about 25 other customers. The district says none of it is returned to Lake Travis. For a homeowner, the lesson is that recycled water lines are a separate network. Never connect one to indoor plumbing. If your lot has any irrigation, a backflow testing visit confirms the device keeps yard water out of the drinking supply.
| Water type | Use it for | Never use it for |
|---|---|---|
| Drinking water | Household taps and appliances | Nothing, it is the household supply |
| Recycled water | Irrigation where offered | Indoor fixtures or drinking |
| Irrigation line off the house supply | Sprinkler zones, behind a backflow device | Direct tie to an indoor line |
Watering rules and lake levels
The district’s site refers to local watering restrictions tied to the levels of Lake Travis and Lake Buchanan. Rules change, so read the current notice before programming a controller. A zone that runs when it should not, or a patch that stays soggy long after a cycle, often means a cracked line or a valve that fails to close. The leak detection page covers the meter test that separates a yard leak from a house leak.
Shut the zone
Turn off the controller for the suspect zone.
Watch the meter
If the dial still moves, the leak is not the sprinkler.
Walk the yard
Look for pooling, geysers or a sunken patch.
Call with notes
Describe the zone and what you saw.
Owner-occupied houses on slopes and lake lots
A mostly owner-occupied town
Census figures show 86.3 percent of Lakeway homes are owner-occupied, and the 2020 count lists 8,314 housing units with about 9 percent vacant. About 16 miles west of Austin at roughly 830 feet, the town sits beside Lake Travis with Hurst Creek running through it. Owners tend to be the ones on the line, which means decisions about a water heater replacement or a repiping job are made by the person at home.
Vacant units matter too. A house left empty for weeks can leak unseen. Shutting the main before a long trip and running taps on return are small steps that spare a repair. The how to find a water leak guide lists the checks.
| Figure | Value |
|---|---|
| Owner-occupied homes | 86.3 percent |
| Housing units, 2020 | 8,314 |
| Vacant units, 2020 | About 9 percent |
| Distance to Austin | About 16 miles |
