Proposed New Wastewater Rates

Shady Hollow MUD is considering changing from a flat rate billing for wastewater collection services to a billing based on actual water usage during the winter months. If adopted, wastewater rates would be determined by a customer’s water usage during the preceding December, January, and February. During these months, outdoor water usage is at a minimum, so the water usage more actually reflects the amount of wastewater actually entering the sewer system. Customers who use less water during those months may see a lower wastewater bill than those using more water. Some people consider this a fairer method than a flat rate because it reflects actual wastewater generation and believes that it encourages water conservation.

The MUD employed a rate consultant to develop rates for the MUD Board to consider. The rate proposal chosen by the Board for consideration is summarized as follows:
A base charge of $50.00 ($57.50 outside the District), with an additional volumetric charge of $11.57 per 1,000 gallons ($13.30 outside the District) for usage between 2,001 and 10,000 gallons. During the first year of the new billing methodology, billing would be capped at 10,000 gallons of monthly water usage during the winter months to allow large water users to transition to the new rates.

The current fixed rate for wastewater is $82.41 for customers within the District ($94.77 outside the District).

Winter Average Water Use In-District Out of District
2,000 gallons or less $50.00 $57.50
5,000 gallons $84.71 $97.40
10,000 gallons or more $142.56 $163.90
Current Rate $82.41 $94.77

The MUD Board will consider this proposed rate change at its regular meeting on July 5, 2022, at 6:30 p.m. at the Shady Hollow Community Center at 3303 Doe Run Drive. Citizens are encouraged to express their views either in person or in the “Contact Us” section of this website.

Current Water Restrictions

For Shady Hollow Residents

Austin residents can protect their lakes, the environment, and their future water supply by watering only one day a week with automatic sprinklers and a second day, if need be, with hoses. Join your neighbors in helping your community and wallet by adhering to the mandatory watering days and times.

By watering only one day a week with a typical automatic irrigation system rather than two to three times a week, a household could save 7,000 to 14,000 gallons a month. That could be a savings of up to $150 a month, depending on how much additional water is used by a household.

The City of Austin is currently in Conservation Stage Water Use Restrictions.

Winter Averaging

Shady Hollow MUD is considering changing the way customers are charged for their wastewater services from a flat rate method to a winter averaging method. No changes are planned for the immediate future, but the MUD will be collecting data this winter to use in deciding whether a change in the current billing method would benefit the MUD’s customers.

Currently the MUD’s customers are charged flat monthly rates for wastewater: $82.41 for customers in the District and $94.77 for customers outside the District. These rates are constant from month to month and are the same for every customer in the same rate class. Shady Hollow MUD has billed this way since it was created in 1980.

While Shady Hollow MUD is not the only utility to use this flat rate method, most utilities determine charges for wastewater service using a method commonly referred to as winter averaging. In this method, the average water use during the winter months is used to determine wastewater charges for the upcoming year. Usually, December, January and February are used because outdoor water use is minimal during those months so the water used gives the best estimate of how much is actually entering the sewer. It is thought that this billing is fairer to small households and encourages water conservation.

After the water use data from this winter is available, the MUD’s rate consultant will be asked to develop rates that will generate the revenue needed to provide wastewater service. The MUD Board will then consider making changes in the current method. This will likely happen in May – June of 2022.

Citizens are welcome to submit any comments or concerns regarding this on the MUD’s website at

Water Conservation- Indoors


Using water more efficiently will not only save money but, more importantly, will also help protect the quality of life of future Texans.

With the vastness of Texas, it’s easy to forget two important facts about our state: we are subject to frequent droughts, and our population is projected to double in the next 50 years. The cost of developing new or additional supplies in that same time period is estimated to be $30.7 billion.

To ensure that we have enough water for current and future Texans, we need to reduce the amount of water we waste.

Possible Water Savings

  • High-efficiency toilets, water-efficient washing machines, rainwater harvesting systems, and water-efficient landscaping can all help reduce water use.
    • A low-flush toilet (or low-flow toilet or high efficiency toilet) is a flush toilet that uses significantly less water than a full-flush toilet. Low flush toilets include single-flush models and dual-flush toilets, which typically use 1.6 US gallons per flush for the full flush and 1.28 US gallons for a reduced flush.
  • Water-efficient showerheads and aerators for faucets can significantly reduce the amount of water you use. In fact, installing a water-efficient showerhead is one of the most effective water-saving steps you can take inside your house.
  • Leaking faucets and toilets can waste thousands of gallons of water monthly, and they are inexpensive to fix. A few small changes in your water use habits can make a huge difference in water savings.

Tips in the Bathroom

  • Replace your showerhead with a water-efficient model.
  • Take short showers.
  • Turn off the water while you are shaving. Fill the sink with hot water instead of letting the water run continuously.
  • Never use the toilet to dispose of trash.
  • Don’t waste water when brushing your teeth or washing your hands. Shut off the water until it’s time to rinse.

Tips in the Kitchen

  • Run the dishwasher only when full.
  • Install faucet aerators. You’ll never notice the difference, and you’ll cut your sink water consumption in half!
  • Keep a container of water in the refrigerator. It will be refreshingly cool and won’t waste water.
  • Dry scrape dishes instead of rinsing. Your dishwasher will take care of the rest.
  • Use garbage disposals sparingly. They can waste water unnecessarily.
  • Conventional washing machines use 32 to 59 gallons of water per load. Use the lowest water level setting on the washing machine for light or partial loads whenever possible.
  • Use cold water as often as possible to save energy and conserve hot water for uses that cold water cannot serve.
