A comprehensive risk ranking for needed improvements at TMWRF identified the aeration system as one of the more critical Capital Improvement Projects that needs to be addressed.  Aeration system work completed to date includes an overall system evaluation that identified prioritized recommended modifications to the aeration system to increase air flow, improve reliability and serviceability.  Aecom, Inc. was hired to design the identified aeration piping improvements.  The proposed improvements will allow for more balanced air delivery to the aeration tanks, improving the plant's ability to continue to reliably treat wastewater to the required standards.

The City of Reno held an open-competitive bid for the proposed work.  Bids were opened on November 22, 2016.  The sole responsive and responsible bidder was K.G. Walters Construction Co., Inc. in the amount of $393,500.00.   Staff researched whether rebidding the project would be prudent, however, based on discussions with other plan holders and the design engineer, rebidding of the project would probably not generate additional bidders nor reduce the cost.

The City of Reno engineering staff will administer the contract.  Cost for the work will be shared pro-rata based on the current ownership of TMWRF (Sparks 31.37% - Reno 68.63%).  Based on this ratio, the City of Sparks' share will be $123,440.95.

Alternatives: Council may reject the reimbursement and direct the manager to provide other alternatives

I move to approve the reimbursement to the City of Reno for Sparks’ share of the  Aeration Piping System Modification project at TMWRF in an amount not to exceed of $123,440.95.
