SCHOFIELD BARRACKS, Hawaii " Gregory Sengsy, Hale Kula Elementary 5th-grade student, digs out composting worms during a student-led tour of Hale Kula Elementary's Saving Your Nation's Energy, or SYNERGY, Outdoor Classroom, here, April 18. Student-led tours showcased the outdoor classroom, which features a rainwater harvesting system, native plant gardens and the Hale Kula Gardening Club's working garden. U.S. Army Garrison-Hawaii and Island Palm Communities partnered to build and fund the outdoor classroom. The Directorate of Public Works, Environmental Division, drafted the design and funded the cistern. The design of the cistern, which falls under USAG-HI's Clean Water Act Management program, demonstrates sustainable landscape management and meets Installation Management Command's water and energy efficiency goals and also achieves permit compliance with the State of Hawaii.
