A public composting restroom at this historic site was built by the Friends of Chrisholm and MetroParks of Butler County to provide amenities for visitors and demonstrate an innovative way to conserve water. In Butler County, abundant high-quality water comes from the Great Miami River and its aquifer, but increasing population and the conversion of agricultural land to residential and industrial use place stress on water availability and quality. The composting restroom uses no water, saving thousands of gallons annually. Its toilets require no septic system, chemicals, sewer, or water lines; waste is deposited in a drum, where it decomposes into nutrients and essential minerals that can be returned to the soil to enrich and fertilize it. The system conserves water, reduces waste volume by 95 percent, recycles organic matter into fertilizer, and avoids the need for septic systems, sewers, chemicals, and water lines. People can help conserve water by knowing the source of their drinking water, buying reusable products, running dishwashers and washing machines only when full, choosing water- and energy-efficient appliances, turning off the tap while brushing teeth or washing dishes, and minimizing shower time. The project was made possible by farsighted donors, with the Friends of Chrisholm, a volunteer group working with MetroParks to preserve and improve the site, providing leadership and the initial investment.
