Stormwater Capture

The most efficient and natural form of water supply solution is stormwater or rainwater. The amount of stormwater absorbed into the ground, and thus, that seeps or filters down (percolates) into underground wells and aquifers, depends on how much permeable surfaces are exposed, how permeable soils are, how much moisture the soils/surfaces already contain, climate, slope of the ground, and other factors. Many of us have witnessed rainstorms and snowmelt where stormwater flows along streets and gutters into storm drains that lead to the ocean or even cause flooding. That water is essentially lost as far as our potable water supply is concerned.

Trying to collect, channel or greater amounts of stormwater or rainwater is what “stormwater capture” is all about. Stormwater capture is a growing science that affects water supply and water quality. Stormwater can be absorbed into the ground in many ways. Mountain streams, lakes, ponds and rivers collect stormwater. Spreading grounds, bio-retention (permeable pavers/surfaces, bioswales, curb cuts, porous asphalt to name just a few examples), rain barrels and cisterns help save precious precipitation.
