The Irma Lewis Seguin Outdoor Learning Center (ILSOLC) now has a fully functioning rainwater harvesting system! The system gathers rainfall from 1,000 square feet of roof surface on the pavilion, and channels it through a gutter and piping system to be stored in a 5,000 gallon tank. From there it is pumped through an underground pipeline to the garden area. The tank is full right now, due to some wonderful rains that fell awhile back. For each 1 inch of rainfall on the 1,000 square foot catchment area, a little over 600 gallons are collected in the tank.

Funding for the system was provided by a grant from the Texas Commission on Environmental Quality to the Guadalupe-Blanco River Authority, working in cooperation with the ILSOLC. Funding from the grant will also provide for construction of other Low Impact Development structures on the Learning Center property such as a rain garden, pervious pavement, and vegetated swales.
