Background and System:

The mission of the Lone Star Groundwater Conservation District, Conroe, is to help Montgomery County progress to a sustainable, balanced portfolio of water resources. During construction of the new 4.9-acre headquarters, the district was presented an opportunity to show that growth in the county could be achieved without sacrificing quality because of water concerns. The district did so by implementing water conservation measures at the facility including installing a rainwater harvesting system.

At the heart of the system is a 15,000-gallon underground storage tank that collects water from the parking lot via a gravel-filled arroyo. Overflow is directed to an onsite retention pond. Four 2,500-gallon above-ground tanks also collect water from the 10,000-square-foot metal roof on the building which is piped to the underground storage tank. The rainwater is used to irrigate trees, grasses, and shrubs at the site.
