Water Use Reduction
Conclusion

In U.S. 476 Billion gallons of fresh water are
consumed each day
Aquifers around the country have dropped more
than 100 feet since 1940
Since 1950 industries have reduced their water
consumption by 36
Typical 100,000sf. Building with standard water
conserving devices can save a minimum of 1
million gallons of water per year
Alternatives to using potable water sources are
available for non-sanitary functions

Conclusion

Landscape irrigation consumes large quantities of
potable water, which can be switched to
non-potable sources.
Native landscaping with lower irrigation
requirements tends to attract native wildlife.
Utility rates for potable water are expected to
increase dramatically in the next few years.
Maintaining natural aquifer conditions is
important to maintain reliable water sources for
future generations

Conclusion

Graywater from sinks, showers and other sources
can be reused to flush toilets and urinals.
Water can be harvested from roof gutters.
Low-flow fixtures, automatic controls and
dry fixtures reduce sewage generation.
On-site wastewater strategies reduce
infrastructure costs as well as provide
independence from the public treatment
systems.
Costs for wastewater treatment
recovery systems must balance with
the anticipated savings

Conclusion

Toilet flushing consumes the most water in
residential and commercial buildings.
Potable water conservation reduces energy use and
chemical inputs at municipal water treatment
works
Water consumption reductions minimize overall
building operating costs.
Water use reductions, allow municipalities
to reduce capital investment needed
for water supply wastewater
treatment infrastructure.
