why conserve
Why conserve?
  • Protect your water quantity and quality
  • Reduce the load to septic or sewer system
  • Save $$$$
  • Save ENERGY used to move or heat water
  • Protect resources for future generations
  • Little effort produces significant results
ways to conserve indoors
Ways to conserve INDOORS
  • Toilets
    • Check for leaks by putting food coloring in tank
    • Reduce number of flushes per day
      • 1 less flush per person/day in US  would save enough water to create a lake one sq. mile 4 ft deep every day!
    • Toilets made before 1993  3-8 gallons per flush; newer toilets use 1.6 gpf
    • Improved toilets can save a family 14,000-17,000 gallons per year
    • Install toilet tummy or 2 liter bottles in tank
  • Turn off water when brushing teeth or

shaving!

ways to conserve indoors1
Ways to conserve INDOORS
  • Shower and Bath
    • Reduce time spent in shower – get a timer!
    • Install low-flow shower head – 2.5 gpm or less
    • Bathe small kids together
    • Reconsider baths – 50 or more gallons!
    • Consider collecting water for plants, etc.
  • Houseplants
    • Collect water from washing produce, cooking, or cleaning fish tank to water plants
    • Put discarded ice cubes in a plant rather

than the sink

ways to conserve indoors2
Ways to conserve INDOORS
  • Kitchen
    • Dishwashers
      • New ones work! Don’t pre-wash dishes
      • Run only when full
    • Faucets
      • Fix Leaks! One drip per second  2,700 gal/year
      • Install low-flow faucet aerators
      • Turn it off when not in use (washing dishes)
    • Consider composting rather than garbage disposal
    • Use as little water as possible when cooking
ways to conserve indoors3
Ways to conserve INDOORS
  • Laundry
    • Consider purchasing energy efficient model (23 gallons per load compared to 40)
    • Use cold setting whenever possible
    • Pre-treat stains to avoid re-washing
    • Only wash full loads, or adjust load size setting
ways to conserve outside
Ways to conserve OUTSIDE
  • Xeriscape – landscape in ways that do not require irrigation
    • Plant species appropriate to your area (native), in practical areas of the yard
    • Use mulch, manure and compost
    • Group plants by water need
    • If watering is necessary, do so in the morning hours
    • Harvest rainwater using a cistern
ways to conserve outside1
Ways to conserve OUTSIDE
  • Check for leaks – hoses, etc.
  • Use the broom instead of hose to clean
  • Install fewer impermeable surfaces
  • Take the car to a carwash that recycles water
  • Install backflow protector on all outdoor faucets and use backflow practices
achieving water conservation
Achieving Water Conservation
  • Changes in Habits
    • Little or no additional cost
    • Quick effect
    • Often temporary
  • Water saving appliances or fixtures
    • Can be expensive
    • Most are easily installed
    • Very effective
    • Often permanent
effect of water conservation
Effect of Water Conservation

Normal use = 68 gallons per day per person

Conservation use = 38 gallons per day per person
