Rainwater harvesting involves collecting runoff from an impervious surface and storing it in a container or basin for later use. The container can range in size from a rain barrel, typically 55 or 90 gallons, to a cistern which can hold hundreds or thousands of gallons of water. Harvested rainwater can supply water for various uses including car washing, toilet flushing, clothes laundering, irrigation, and fire fighting. Rainwater harvesting helps reduce dependence on the drinking water supply for non-consumptive uses and reduces stormwater runoff. Requiring the utilization of porous paving for parking lots, and looking to increase the number of tree boxes alongside or within paved areas can allow rainwater to seep into the soil beneath. With our wetlands being compromised, and sustainability as our target, it is increasingly important that Wisconsin adopt a variety of green approaches to infrastructure development and water reclamation.
