Water Conservation

Catch basins and rain barrels can collect storm water runoff from roofs that can then be used as irrigation for landscaping. Also low-flow fixtures and aerators or dual-flush toilets can increase water efficiency. "Grey water" systems which reuse rinse water from sinks and washing machines in toilets and for landscaping also conserve water.
