Title
Resolution - A Resolution of the City Council of the City of Mansfield, Texas, Approving a 24-month Agreement with In-Pipe Technology in an amount not to exceed $312,000 Annually to Install, Maintain Equipment, and Treat Wastewater Through Microbial Dosing in the Wastewater Collection System; Finding that the Meeting at Which this Resolution is Passed is Open to the Public as Required By Law; and Declaring an Effective Date (Utility Fund)
Requested Action
Consider the attached Resolution authorizing a two-year agreement, with 3 optional renewal years, for microbial dosing in the wastewater collection system.
Recommendation
City staff recommends approval of this resolution to continue wastewater pretreatment efforts aimed at reducing biochemical oxygen demand (BOD) and total suspended solids (TSS) concentrations in the collection system.
Description/History
In-Pipe Technology has had success over the previous year reducing the strength of the wastewater in our system. We propose to continue this service in the interest of further improvement. In-Pipe Technologies uses microbial dosing in our wastewater collection lines at strategic locations to remove BOD and TSS in our effluent flow.
Justification
TRA (Trinity River Authority) imposes surcharges based on the strength of the wastewater we send to them for treatment. The pretreatment measures we have implemented have helped to control and reduce the overall cost of these charges. The savings in our wastewater treatment budget have exceeded the monthly cost from In-Pipe. Therefore, this is a net neutral cost and will be expensed from the cost of sewer treatment.
