Title
Resolution to Approve a Purchase Order with Trojan Technologies Inc. for Ultraviolet Disinfection System Replacement Parts at the Wastewater Treatment Plant ($60,000.00)
Memorandum
Your approval is requested to authorize a Purchase Order with Trojan Technologies Inc. in the amount of $60,000.00 for replacement parts to maintain the ultraviolet (UV) disinfection system at the Wastewater Treatment Plant (WWTP).

The UV system enables the WWTP to satisfy its National Pollutant Discharge Elimination System permit requirement for disinfection of the plant’s final effluent. Operation of the UV system has allowed the WWTP to discontinue the storage and use of two extremely hazardous chemicals, gaseous chlorine and sulfur dioxide. In addition, UV disinfection has eliminated the deleterious effects associated with chlorine disinfection on the Huron River. Replacing burnt and worn out parts (bulbs, ballasts, and hydraulic components) in the UV system is a recurring maintenance activity necessary for the proper function of the system. Trojan Technologies Inc. is the sole source from which system components for the WWTP’s UV disinfection system can be purchased.

Trojan Technologies Inc. received Human Rights approval on April 5, 2007, and complies with the City’s living wage requirements.

Funds to finance this purchase are included in the approved FY08 WWTP Operation and Maintenance Budget for the Sewage Disposal System.
