HAWC’s goal is to protect the future of drinking water and we encourage all of our customers to do the same. HAWC is fortunate to have an adequate supply of water for everyday needs, however it is important to use this water wisely. Conserving water helps to avoid the considerable expense of developing new water supply sources, and ensures that we will continue to have adequate supplies to service our customers.

Five Ways to Reduce Wasteful Water Usage
- Leaking toilets & faucets are the most common source of increased water usage.
Hundreds of gallons of water can be lost from a toilet leak daily! (Refer to Leak Detection for additional information).
- Do not over-water plants and lawns. For best results, try morning watering.
- Avoid washing down paved areas. Also try using a bucket when washing the car.
- Use the washing machine & dishwasher wisely. Half loads can use just as much water as full loads.
- Avoid running the faucet while washing your hands, brushing your teeth, etc.
Wise Water Use for Dishes & Laundry
More than 10% of all water used in the home is used in the washing machine. An automatic clothes washer, at full cycle and at the highest water level, uses approximately 30-35 gallons of water.
Dishwashers are also a potential heavy user, requiring 25 gallons for a full cycle.
Washing dishes with the tap running takes five gallons per minute – approximately 30 gallons per average washing.
Use the dishwasher & washing machine wisely. Half loads can use just as much water as full loads.
In the average household, water use doubles in the summer, primarily due to landscape irrigation. But, conserving water does not have to mean a dry, brown landscape.
In the garden, try these water-conserving techniques:
- Use a variety of attractive drought tolerant plants in your garden to save water.
- Many drought-tolerant plants are prolific bloomers. Plus, by carefully choosing foliage colors and textures for contrast, you can bring color interest to the garden year-round.
- Even drought-resistant plants require some initial watering to become established. However, once they are established, drought-resistant plants will get by on considerably less water than we have been accustomed to lavishing on our landscape. Add compost to your soil to improve its water-holding capacity.
- Use a drip irrigation system to apply water slowly, reducing run-off and promoting deep rooting.
- Mulch, which can be made from readily available wood chips or leaf mold, acts as a blanket to keep in moisture and helps prevent erosion, soil compression and weeds.
- Preserve existing trees. Established plants are often adapted to low water conditions. Porous paving materials such as brick, decomposed granite, or gravel used in patios and walk-ways help keep water in the garden rather than in the gutter.
- Set automatic timing devices, which allow efficient watering on a schedule suited to each area of the landscape.
- When planting, remember that smaller-size container plants require less water to become established.
- Use recycled water to save even more water in your garden. Waste water may be the simplest way to stretch your water budget during the hot summer months. Grey water, which is recycled shower, bath, and laundry water, can be used to keep thirsty plants alive, but some precautions should be followed.
- Use only water from clothes washing, bathing, or the bathroom sink. Do not use water that has come in contact with soiled diapers, meat or poultry, or anyone with an infectious disease.
- Note: Grey water is not considered safe for consumption.
For further information regarding the safe use of grey water contact your local health department.
Ultra-Low Flush Toilets
Switching to an ultra-low flush toilet is an effective way to make your home or office more water efficient. Ultra-low flush (ULF) toilets use no more than 1.6 gallons per flush (gpf) rather than 3.5 to 7 gallons of water used by other designs.
Questions and Answers about ULFs
- How much water can I save by switching to a ULF toilet? A household of four people with a standard five-gallon-per-flush toilet would save approximately 60 gallons per day, or about 22,000 gallons per year.
- How do ULF toilets work? Ultra-low flush toilets use an efficient bowl design and increased flushing velocities to remove waste, rather than simply using large amounts of water for flushing. ULF’s use either Gravity Flush or Pressurized Flush technology, and vary by model/manufacturer.
- Do ULF toilets cost more? As with other toilets, ULFs come in a broad range of prices. Many models are available for about $100 and can run as high as $400 or more for the decorator models.
- Are these toilets available in many colors and styles? Yes. ULF toilets can be purchased in the same spectrum of decorator colors as conventional toilets. Various styles are available in plain rim, elongated rim, and high handicapped models.
