Water Conservation

The Board of Directors of Harris County Municipal Utility District No 148 encourages the conservation of water, our most valuable resource. Water conservation is good for the environment and our pocketbooks! Here are a few things about water conservation you might need to know:

Why Conserve Water?

Water conservation is the most cost-effective and environmentally sound way to reduce our demand for water. This stretches our supplies farther. It protects Houston and Texas. Using less water also puts less pressure on our sewage treatment facilities. Saving water also saves energy.

What Can I Do?

There are many effective ways to conserve water in and around your home. Look through this list for ways that will work for you. Indoor savings are based on a family of two adults and one child.

Ten Ways to Save the Most

  1. Water your lawn only when it needs it. Step on your grass. If it springs back when your foot is one it, it does not need water. So water your yard or set your sprinklers for more days in between watering. Saves 750-1,500 gallons per month. Better yet, especially in times of drought, water with a hose. And best of all, convert your lawn to native plants.
  2. Fix leaky faucets and plumbing joints. Saves 20 gallons per day for every leak stopped.
  3. Don’t run the hose while washing your car. Use a bucket of water and a quick hose rinse at the end. Saves 150 gallons each time. For a two-car family, that’s up to 1,200 gallons a month.
  4. Install water-saving shower heads or flow restrictors. Saves 500 to 800 gallons per month.
  5. Run only full loads in the washing machine and dishwasher. Saves 300 to 800 gallons per month.
  6. Shorten your showers. Even a one or two minute reduction can save up to 700 gallons per month.
  7. Use a broom instead of a hose to clean driveways and sidewalks. Saves up to 150 gallons or more each time. At once a week, that’s more than 600 gallons a month.
  8. Don’t use your toilet as an ashtray or wastebacket. Saves 400 to 600 gallons per month.
  9. Capture tap water while you wait for hot water to come down the pipes, catch the flow in a watering can to use later on house plants or your garden. Saves 200 to 300 gallons per month.
  10. Don’t water the sidewalks, driveway or gutter. Adjust your sprinklers or move the hose so that water lands on your lawn or garden where it belongs–and only there. Saves 500 gallons per month.

Tips for the Bathroom

  1. Put a plastic bottle or a plastic bag weighted with pebbles and filled with water in your toilet tank. Displacing water in this manner allows you to use less water with each flush. Saves 5 to 10 gallons a day. That’s up to 300 gallons a month, even more for large families. Better yet, for even greater savings, replace your water-guzzling five to seven gallon a flush toilet with a one and a half gallon, ultra-low flush model.
  2. If you’re taking a hot shower, don’t waste cold water while waiting for hot water to reach the shower head. Catch that water in a container to use on your outside plants or to flush your toilet. Saves 200 to 300 gallons a month.
  3. Check toilet for leaks. Put dye tablets or food coloring into the tank. If color appears in the bowl without flushing, there is a leak that should be repaired. Saves 400 gallons a month.
  4. Turn off the water while brushing your teeth. Saves three gallons each day.
  5. Turn off the water while shaving. Fill the botton of the sink with a few inches of water to rinse your razor. Saves three gallons each day.

Tips for the Kitchen

  1. If you wash dishes by hand–and that’s the best way–don’t leave the water running for rinsing. If you have two sinks, fill one with rinse water. If you only have one sink, use a spray device or short blasts instead of letting the water run. Saves 200 to 500 gallons a month.
  2. When washing dishes by hand, use the least amount of detergent possible. This minimizes rinse water needed. Saves 50 to 150 gallons a month.
  3. Keep a bottle of drinking water in the refrigerator. This beats the wastful habit of running tap water to cool it for drinking. Saves 200 to 300 gallons a month.
  4. Don’t defrost frozen foods with running water. Either plan ahead by placing frozen items in the refrigerator overnight or defrost them in the microwave. Saves 50 to 150 gallons a month.
  5. Don’t let the faucet run while you clean vegetables. Rinse them in a filled sink or pan. Saves 150 to 250 gallons a month.
  6. Use the garbage disposal less and the garbage more (even better–compost!). Saves 50 to 150 gallons a month.

Tips for the Outside

  1. Put a layer of mulch around trees and plants. Chunks of bark, peat moss or gravel slows down evaporation. Saves 750 to 1,500 gallons a month.
  2. If you have a pool, use a pool cover to cut down on evaporation. It will also keep your pool cleaner and reduce the need to add chemicals. Saves 1,000 gallons a month.
  3. Water during the cool parts of the day. Early morning is better than dusk since it helps prevent the growth of fungus. Saves 300 gallons.
  4. Don’t water the lawn on windy days. There is too much evaporation. Can was up to 300 gallons in one watering.
  5. Cut down on watering on cool and overcast days and don’t water in the rain. Adjust or deactivate automatic sprinklers. Can save up to 300 gallons each time.
  6. Set lawn mower blades one notch higher. Longer grass means less evaporation. Saves 500 to 1,500 gallons each month.
  7. Have an evaporative air conditioner? Direct the water drain line to a flower bed, tree base, or lawn.
  8. Drive your car onto a lawn to wash it. Rinse water can help water the grass.
  9. Tell your children not to play with the garden hose. Saves 10 gallons a minute.
  10. If you allow your children to play in the sprinklers, make sure it is only when you are watering the yard–if it is not too cool at that time of day.
  11. Xeriscape–replace your lawn and high-water-using trees and plants with less thirsty ones. But do this only in wet years. Even drought resistant plantings take extra water to get them going. That’ll save 750 to 1,500 gallons a month.
  12. When taking your car to a car wash–a good idea for saving water–be sure it is one of the many that recycles its wash water.
  13. Dispose of hazardous materials properly! One quart of oil can contaminate 250,000 gallons of water, effectively eliminating that much water from our water supply. Contact Harris County for proper disposal options.
