The aqueduct is one of several water features that harvests water for the 70,000-gallon rainwater collection system.
The Wildflower Centerís striking architecture is constructed to conserve resources. A central irrigation system collects rainwater from 17,000 square feet of roof, or about 10,200 gallons per inch of rain. The separate entry cistern is fed by 1,167 square feet of roof, collecting 700 gallons per inch of rain. Another cistern and ponds collect water for re-circulation.
