Our Story

​Founded in 2010 by direct competitors in the turfgrass industry, the Turfgrass Water Conservation Alliance (TWCA) is a 501 c(3) non-profit committed to water conservation and dedicated to preserving the ecological benefits of turfgrass in the managed environment.
Our approach to conservation relies on the 3rd party peer review of objective data to qualify only those turfgrasses that demonstrate a statistically significant water saving potential over conventional varieties of the same species.  By testing with research collaborators in locations across North America, the TWCA eliminates confounding factors such as soil type, heat, and pest management from the results.
