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.
