Water Waste

The problem

Urban water systems are currently inefficient, and there are much better ways to use the water that travels through our systems that make use of different types of water for different purposes.

Graywater is defined as any water used in a home except for toilet water. Blackwater is toilet water. Stormwater is roof runoff and sometimes rainwater.


40% to 50%

of wastewater generated per household is graywater

25% 

of wastewater is toilet water

70%

water savings experienced by some existing pilot sustainability systems

our Solution

Create a framework that guides decentralized non-potable water systems and allows for reuse of graywater, blackwater, and stormwater. This framework would allow urban areas to determine the level of treatment needed for different water sources to reduce health risks and save on cost and energy use.
