Boil Water Notice
Boil Water Notification
The boil water notice states that water for consumption, cooking and ice making should be boiled and cooled prior to consumption. This notice is given as a precaution to ensure destruction of any bacteria that may have become present when water pressure dropped below 20 psi. As soon as the results from the bacteriological samples are available, water system officials will notify you that the boil water notice has been lifted and it will no longer be necessary to boil the water.
If you have questions or concerns please contact our Waterline Maintenance Division at 512-218-5555, 24 hours a day, 7 days a week.
Zebra mussels are having a devastating effect on the state’s natural resources. These highly destructive, invasive species are spreading across Texas lakes by hitching a ride on boats, trailers, jet ski’s, fishing equipment and swimming gear. Zebra mussels only grow to about 1 1/2 inches long; however, they multiply rapidly, one million eggs spawned by one female each year, and with the lack of natural predators in Texas lakes, they can cause tremendous environmental and economic damage.
This invasive species has already invaded several Texas lakes, and could take over all freshwater sources in Texas. The local lakes we use, not only for recreation but also for our water supply, have been classified as infested with zebra mussels. Lake Georgetown, Stillhouse Hollow Lake and Lake Travis are among the 14 infested Texas lakes.
Zebra mussels pose a devastating threat to our state’s aquatic ecosystems, private property and water supply systems. They cause recreational hardships, damage to the ecosystem and financially impact taxpayers.
This video is actual footage of zebra mussels in Lake Georgetown — our primary water source.
- Desecrate beaches with their sharp shells.
- Decreases boat fuel efficiency when attached.
- Damages boat motors, water pumps, air conditioners, and navigation buoys.
- Caused an algal bloom that led to a “do not drink” order for half a million Lake Erie residents.
- Harm native species, including popular sport fish, taking over habitats and damaging lake ecology.
- Reduces the availability of tiny food particles (zooplankton and phytoplankton), impacting filter feeding fish, important prey for bass and other sportfish.
- Reduces native mussel and crayfish populations – as zebra mussels can attach to the shells and exoskeletons of these native species and suffocate them.
- Disrupts water supplies by completely clogging pipelines and damaging water intake structures, making water more expensive.
- Decreased property value up to 19% in some areas infested with aquatic invasive species.
What can you do?
- Spread the word!
- Clean and thoroughly dry every item that was in or near the water (swimsuits, water shoes, towels, buckets, toys, rafts, etc.)
- Clean and dry your dog(s)
- Report any sightings to TexasInvasives.org
- If you see a violation, report it to 800-792-4263
- CLEAN, DRAIN AND DRY your boat, trailer and gear every time you leave a body of water!
- Remove all plants, animals and foreign objects from hulls, propellers, intakes, trailers, and gear before leaving a launch area.
- Drain all water from your boat, including the motor, bilge, live wells and bait buckets, before leaving a lake.
- Dry for a week or more before entering another water body. If unable to let it dry, wash it with a high-pressure washer and hot (at least 140-degree) soapy water.
Transporting Zebra Mussels is ILLEGAL
Possession or transportation of zebra mussels in Texas is a Class C misdemeanor for the first offense, punishable by a fine of up to $500. Repeat offenses can be elevated to a Class B misdemeanor, punishable by a fine of up to $2,000, jail time up to 180 days, or both.
State law requires boaters to drain all water from their vessel, including live wells, bilges, motors and any other receptacles or water intake systems before leaving or approaching public waters. This applies to all types and sizes of boats used on fresh waters.

While no mandatory restrictions are currently in effect in 2021, the City encourages you to practice smart water usage year-round. Only water on your designated day(s) if needed, and keep in mind that water waste is always prohibited.
Report Water Waste
If you see water spraying the sidewalk, running into the street, or any other water waste, please report the violation via EMAIL, 512-671-2872, or on the City’s RRTX mobile app. Please include the date, time, location (address or intersection), and type of violation (i.e., water running into the street). Your report is confidential.
You can find the full Drought Contingency Plan here.

Q. Can my group hold a charity car wash or fund-raiser car wash while we’re in water restrictions?
A. A charity or fund-raising car wash can only be held during the property’s allowed outdoor irrigation times and days, while we’re in Stage 1 or 2 drought restrictions. For example, if the car wash is going to be held in a bank parking lot, it can be held on a Friday or a Tuesday before 10am or after 7pm because that’s when that property is allowed to use water outdoors.
If the car wash is held at a commercial car wash facility, then it can be held any day at any time; it is exempt to the restrictions. Commercial car washes control the runoff from the property and use more efficient equipment to wash the vehicles.
Q. Can I fill my swimming pool?
A. Yes, you can fill your swimming pool on your assigned outdoor irrigation day.
Q. I just had new landscaping installed at my house that needs to be watered more frequently. What do I do?
A. Newly planted landscaping does need to be watered more frequently in order to establish it. If more than 25% of your yard has new sod or landscaped area, you may apply for a 30-day watering variance. Fill out the form and submit it per the instructions.
Q. Can I pressure wash my house?
A. Yes, you can pressure wash your house on your assigned outdoor irrigation day. A commercial company that provides pressure washing as its main business is not restricted to specific watering days.
Q. I see a property that is wasting water or watering on a day that isn’t their assigned water day. Who do I report that to?
A. Report water violations to the Water Conservation Program by email or by calling 512-671-2872. You must include a property name, address, and a description of the violation (i.e. watering Monday at 2pm or lots of water running down the street) in order for staff to follow up on the complaint. All complaints are kept confidential.
Q. Can I use a slip-n-slide or other water toy, or inflatable water-using piece of equipment?
A. Yes, provided there is no water run-off from the property where it’s being used. Use it in the grass or other pervious area so the water soaks into the ground.
Q. When can I wash my vehicle?
A. You can wash your vehicle on your designated irrigation day at your house, or you can take it to a commercial car wash facility any time they are open.
Commercial car washes are not restricted during water restrictions because they are more efficient than washing a vehicle at a private residence. They capture and treat the dirty, soapy water onsite, or through the waste water lines, rather than letting the water drain into the storm water system, which is what happens when folks wash vehicles at home. The commercial equipment uses more pressure and less gallons of water per minute than home washes, so they overall use less water per vehicle.
