Investigate potentially useful applications of grey-water, from the large scale (e.g. ice rinks) to the small scale (e.g. small restroom facilities) on parkland. Use of grey-water can help reduce the demand on conventional potable water sources as well as on water-treatment plants. This project would require investigation into specific opportunities for the use of grey water as well as the permitting and other regulatory requirements associated with approval of such projects in Montgomery County.
