Conservation – aka "Don't Waste Water"

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

The PK Water Supply system was built to provide potable water to the community for household use and there is not an infinite supply. Cities have other supplies available to support their demand, but we have no secondary source.

That is why it is so important not to use the water excessively or not waste the water. A few small changes in your water use habits can make a huge difference in water savings.

Why Conserve?

According to the Texas State Water Plan, Texas' population is projected to increase 90% by 2050 and total municipal water demand is projected to increase by only 67%. Despite the water savings projected from conservation efforts in the next fifty years, water supply from existing sources will meet only 75% of the demand. By using our precious water resources more efficiently we are better prepared for periodic drought periods common to Texas and the high peak demand we experience in the summer heat.

Conservation Tips


  1. Replace your showerhead with a water efficient model. This saves as much as 6 gallons of water per minute
  2. Replace your old toilet with a water efficient toilet. This saves as much as 5 gallons per flush. If you can't make yourself part with that old toilet, at least install a displacement device. Use a plastic bag or bottle filled with water to reduce the volume of water in the tank but still provide enough for flushing.
  3. Pay attention to those dripping sounds and fix the leaks. Don't forget about those sneaky silent leaks. Add a few drops of food coloring to the water in your toilet tank, but do not flush. If the coloring appears in the bowl within a few minutes, the toilet has a leak.
  4. A family of 4 will use 881 gallons of water per week just to flush.
  5. A 5 minute shower will use 15-25 gallons of water while the average bath will use 37 to 50 gallons.
  6. Turn off the water while brushing your teeth and save up to 4 gallons per minute.
  7. Plug the sink to shave and save 100 gallons a week.


  1. Never run the dishwasher without a full load. If you buy a new machine, ask for water saving model.
  2. Install faucet aerators. It will cut your sink water consumption in half, but you will never notice the difference.
  3. Soak pans rather than scrubbing them while the water is running.
  4. Don't run the water while washing dishes by hand, fill a basin or pan for rinsing.
  5. If you have a newer model dishwasher, don't rinse dishes before placing them in the dishwasher. Let it do its' job.


  1. Wash only full loads. Conventional washing machines use up to 55 gallons of water per load.
  2. Buy a high efficiency washer. They use at least 40% less water and energy as conventional washers.

Outdoor Conservation Tips

  1. Don't over-water your lawn! When you step on it and it springs back up – it doesn't need water. If it lays flat, it is time to water.
  2. Don't scalp lawns when mowing during hot weather. Taller grass holds moisture better. Catch water in an empty tuna can to measure sprinkler output. An inch of water is enough to apply each time you irrigate.
  3. If you are washing your car at home, use a bucket of soapy water and use a hose nozzle that shuts off the water while your scrub.
  4. Consider xeriscape landscaping as it uses low water usage plants native to the area.
  5. Use 2 to 4 inches or organic mulch around plants to reduce evaporation and same hundreds of gallons of water per year.
  6. Set a kitchen timer when using the hose and sprinkler as a reminder to turn it off. A running hose can discharge up to 10 gallons per minute.
  7. Use a broom to clean porches and sidewalks.
  8. Use a spray nozzle on the hose for all outside use. Don't leave the water hose running.

* Learn how to turn off the water at the shut-off valve in case of a leak.
