The Metropolitan Sewer District of Greater Cincinnati serves the wastewater removal and treatment needs of Hamilton County, Ohio. The Sewer District uses a variety of vehicles and equipment, including vans, bulldosers, cranes, service trucks and cars. Operation of the equipment involves a total of 180 keys, used as needed by the district’s 150 or so employees.

A KeyWatcher® key control and management system makes it possible to keep up with the keys. Three cabinets are located side-by-side on a catwalk in the Sewer District’s large garage. The garage operates 24 hours a day, seven days a week, so employees have access to the cabinets anytime, including the middle of the night. Three additional boxes are located elsewhere in the department – one in the maintenance shop, one in another wing of the building and one in the mechanics’ area.
