The Fleet Services Department oversees the inventories for the Agricultural Service Department, Municipal Services Department, and Shop Departments. This includes the management of parts room and operations yard inventories such as filters, lubricants, culverts, etc. The effective management of inventories is necessary and regular turnover to curtail accumulation of old or unused parts ensures space is available for necessary stock. Inventory control is necessary to ensure inventory costs are maintained, and assists in determining and maintaining adequate levels of stock.
