Funding is provided by Fund 336 – Water & Sewer System <br />Improvements Fund, with available program funding of $2,000,000. <br />Project summary statement: <br />Staff seeks to amend a Professional Services Agreement with Carollo Engineers Inc. for <br />the WPCF Combined Conveyance Improvement project. The original agreement <br />included pre-design services only. The work encompassed within the additional scope <br />and fee includes services to complete the design along with assistance during bidding. <br />Currently during storm events, peak wet weather flows into the Water Pollution Control <br />Facility are directed away from the South Plant and are conveyed directly to the AC <br />Ponds. This action can disturb the solids collection within the AC Ponds and wash them <br />into the Oxidation Ponds. <br />This project will construct a bypass pipeline that will reroute the peak wet weather flows <br />directly to the Oxidation Ponds. The project will include the construction of a new <br />junction chamber along with the construction of a new pipeline from this new junction <br />chamber to the Recirculation Channel. This project will also help facilitate the future <br />nutrient removal upgrades that are foreseen as necessary to meet future treatment <br />requirements. <br />Recommendation (exact action requested of Council): <br />Authorize the Mayor to sign Amendment No. 1 to the Professional Services Agreement <br />with Carollo Engineers Inc. for the WPCF Combined Conveyance Improvement project in <br />the amount not to exceed of $1,054,281.00.
