The heating and cooling system isn’t the only place where
treated wastewater is reused in this building. Treated effluent is also used in
the toilets in this building. This water obviously doesn’t have to be clean
enough to drink, so this is another way to conserve water by recycling
wastewater. If you go to the bathroom in this building, the water is slightly
off-color – that’s normal. The water we discharge from the plant has been
disinfected, but still contains some organic matter and solids. This water is
clean enough to go back to nature without harming humans or wildlife, but would
need to be treated further for it to be drinking water quality.
The sinks in the restrooms are provided with clean and
potable water, and they use low-flow fixtures to conserve water. Overall, this
building uses 30% less potable water than a standard building design would.
