Water Conservation

Design Considerations:

Water Recovery- Water conservation should be promoted by water recycling systems that limit demand and reduce sewage.  Use water that is of lower quality than drinking water, like reclaimed wastewater effluent, gray water, or runoff from ground surfaces for toilet flushing or the irrigation of vegetation.  In the U.S. nearly all of our water supply is of drinking quality, yet toilet flushing constitutes the largest use of indoor water.

Water Saving Fixtures-  Water conservation should be promoted by specifying low-use water fixtures and appliances.  Installing water-saving fixtures is easy, inexpensive, and provides immediate cost savings.  The installation of new low-flush toilets, faucet aerators, efficient showerheads, and efficient appliances can cut water use by over 30%.  Install fixtures that use 20% less water than the water usage requirements in the Energy Policy Act of 1992. 
Use fixtures that have been manufactured locally in an "sustaining" manner, to avoid environmental impacts of transportation.

Water Efficient Landscaping-  All exterior plantings should use plants tolerant of climate, soils, and natural water availability, and they should not need to receive watering from municipal potable water after the period of establishment is complete.
