Curb cutting allows street runoff water to be harvested in the sidewalk strip. This is a source of irrigation water, as well as a way to prevent stormwater runoff pollution into waterways.

After the cistern fills, any additional rainwater exits through the overflow pipe. This water can be directed to swales or sunken rain gardens for further "harvesting" and infiltration into the soil. The cistern is elevated on blocks to create more gravity flow from the bottom outet.   This cistern was constructed by the Watershed Management Group in Tucson, AZ.

This galvanized culvert-style cistern is part of a water demonstration project at a city council office in Tucon, AZ, constructed by the Watershed Management Group.

This ferrocement cistern is a lower cost way to collect rainwater. It has a "first flush" vertical pipe which captures the first dirtiest rainwater.  It was designed and built by the Watershed Management Group in Tucson, AZ.

This 11,000 gallon (3 story) cistern collects rainwater from the roof of the Architecture Building at the University of Arizona to irrigate the surrounding landscape.
