Rainwater Catchment. Another option, while not truly
recycling, is to set up a rainwater catchment system. Capturing
the natural rainfall and using it to irrigate during arid periods
will remove the irrigation demand from your existing source and
thus conserve that source.
Swimming Pools and Spas
Conventional and Water-Efficient. Though swimming
pools and spas may account for only a small percentage of the
total water used at a military installation, there are some
simple steps that should be implemented to reduce water usage
while conserving energy:
a) Cover the pool or spa when not in use. A pool
cover can reduce water evaporation by as much as 90-95 percent.
It reduces the need for pool filter backwashing by keeping out
foreign matter, and it acts as a solar heater when placed over
outdoor pools and spas.
b) Lower the water level in the pool or spa. This
prevents water loss due to splashing, and also decreases the
total volume of water that must be heated and cleaned. If you
use pool skimmers for cleaning, ensure that you do not lower the
water level so far that the skimmers become useless.
c) Use chemicals properly to maintain water quality
and reduce the need for cleaning and refilling.
For new construction, consider indoor rather than
outdoor pools and spas. They require less heating, experience
