Storm Water Treatment Wetlands

Stormwater Treatment Wetlands are an important tool in addressing water quality, and a viable Best Management Practice (BMP) for this region.

Stormwater wetlands are emerging as one of the very best ways to clean up polluted stormwater on the Texas Gulf Coast. Wetlands are abundant in our area because we are so flat and wet, and they play a critical role in our natural ecology. Because we are so flat and wet, we have developed a very extensive stormwater detention and conveyance system. Wetlands can easily be engineered into this system –a marriage of engineering and nature that could be our best bet for meeting water quality goals in the face of rapid population growth on the coast. This marriage would also do much to beautify our communities and help to restore some of the functions of the natural wetlands we have lost.
