Texas Rainwater Harvesting Systems Tours

Sea Scouts Galveston Texas / Landscaping Irrigation / LEED Platinum

The recently completed, 8 acre Sea Scout base in Galveston, TX has incorporated CorGal water tanks for irrigation, and was constructed by Seattle based RainBank Rainwater Systems.


Four storage tanks on both sides of the building will collect roof runoff from the green roof.  Additionally, below grade storm water collection wet wells will collect runoff from area site drains and serve as secondary storage.


Rainwater from the main building green roof will be directed to the top of one tank on each end of the building with equalization between all four tanks. If the volume in the tanks is not adequate for an irrigation cycle, the four cisterns will be filled automatically to an adequate level from the wet wells, conveyed by a 7.5 HP 270 GPM.

 The overflow from the cisterns is routed to passive infiltration.


A Platinum LEED rating for green building was achieved on this project.
