The County of Sonoma is engaged in a comprehensive energy project to increase the energy efficiency of the County facilities and reduce greenhouse gas emissions from facility operations. A major part of this effort is to increase the plumbing efficiency in the Main Adult Detention Facility (MADF). The scope of work at MADF was to replace the existing valves for toilet and wash basins in each of the 700 cells with electronically controlled retrofits. These new controls will allow detention staff to prevent wasteful flushing by inmates by limiting the number of flushes per hour and to reduce the volume of water for each toilet flush.
