Stormwater is water that comes from precipitation and ice/snow melt – it either soaks into exposed soil or remains on top of impervious surfaces, like pavement or rooftops. Stormwater will eventually evaporate off of a level surface, but most often it flows as runoff to another location. While runoff is flowing to a storm drain or nearby water body, it picks up pollutants along its path. This runoff can cause stream impairment, flooding, pollution, fish & wildlife habitat loss, soil erosion, and reduced groundwater levels.

THERE ARE VARYING DEGREES OF “DIRTY” WHEN IT COMES TO STORMWATER.
In the diagram below, you’ll see various stormwater characteristics/contaminants with corresponding method(s) of treatment.

WANT TO TRY TREATING STORMWATER ON YOUR OWN?
If your stormwater issue falls in the detention and/or passive BMPs sections, you could try treating the stormwater on your own. We’ve created several project instruction sheets for do-it-yourself best management practices. We call them #DIYBMPs, and all seven are available here for complimentary download. You’ll notice each sheet lists target contaminants, estimated flow, a cost estimate to complete, a list of necessary parts and suggestions of where to purchase those parts locally.

PASSIVE WATER TREATMENT NOT MEETING STORMWATER REQUIREMENTS?
Not all stormwater can be effectively treated with passive options – that’s where WaterTectonics comes in. Below is a small sampling of industries that we serve.
