A biosand filter is designed for use in areas without electrical power and has been shown to improve water quality when compared to a surface water source. The filter system was designed and built as a class project for the Rose-Hulman Institute of Technology course Appropriate Technology for Developing Countries and inspired by an existing gravity fed system in Panama. The operation of the filter system has provided a number of lessons about component reliability and opportunities for improvements.
