PREVIOUS COUNCIL ACTION: On November 12, 2018, the City Council Approved Resolution No. 14081, selecting Brown and Caldwell, Inc as the Engineer of Record for the Wastewater Treatment Department. BACKGROUND: The Wastewater Department has been addressing selenium and sulfate issues in the Arkansas River Basin for more than 25 years. Naturally occurring selenium and sulfate are known to enter the city sewer collection system through the infiltration and inflow of groundwater. The sanitary sewer collection system conveys sewage and the groundwater to the James R. DiIorio Water Reclamation Facility. Approximately 50 percent of the selenium and very little sulfate is removed during the treatment process. The purpose of this project is to pilot multiple technologies in geographical locations with groundwater high in selenium and sulfate. These technologies, not previously used by the Wastewater Department, are capable of identifying and locating sources of groundwater infiltration and inflow entering the sanitary sewer collection system. FINANCIAL IMPLICATIONS: The cost of the agreement with Brown and Caldwell to provide design services for the rehabilitation project will not exceed $556,897.60. Funds are available from the Sewer User Fund and have been appropriated to Project No. WW1503. BOARD/COMMISSION RECOMMENDATION: Not applicable STAKEHOLDER PROCESS: None ALTERNATIVES: The no-action alternative will eliminate the opportunity to collect data that identifies where infiltration and inflow occur in the sanitary sewer collection system. Without this data, it is unknown how best to rehabilitate the sanitary sewer mains to stop infiltration and inflow containing selenium and sulfate. RECOMMENDATION: Approval of the Ordinance.
