Three water systems
This illustration shows the three water systems. Each uses a different set of pipes.
In the drawing:
Turquoise blue is drinking water
Brown is wastewater
Light blue is storm water
Storm Water runs off rooftops, driveways and other hard surfaces. Once storm water goes down a storm drain, it is piped into the nearest creek. Storm water does not go to a treatment plant.
