Abstract This chapter offers a general discussion of one of the more prominent issues facing America today, such as water conservation and using water more efficiently. Wastewater Strategy and Water Reuse/Recycling Reclaimed Water versus Gray water SYSTEMS are defined and explained. Also explained is the LEED Innovative Wastewater Technologies credit and its intent to reduce wastewater generation and potable water demand, as well as increase the recharge of local aquifers. Best practice strategies for landscape irrigation are elucidated. The various types of toilets (e.g., high efficiency, dual flush, and composting toilets), urinals (e.g., waterless urinals) and metering faucets, aerators and flow-optimized showerheads are also examined. Baseline water consumption calculations are explained and finally, retention and detention ponds, bioswales, and other systems are discussed.
