Willoughby’s WMSII system takes plumbing fixture water control from inmates and puts it back in the hands of prison officials, which can result in water/sewage usage reduction of up to 50%. The system is simple to install using common connectors and color-coded wiring. Water usage is reduced through fixed scheduling, dynamic usage or cycle-timing control. Facility officials have the ability to lock out toilets, sinks and showers from a central PC and detect/prevent toilet overflows. The system also provides the ability to control several different devices.
