Title: Consideration and possible approval of reimbursement to the City of Reno in the amount of $55,010.43 for Sparks’ share of contract AC-5242 with HDR Inc. for engineering services associated with the Nitrification System Control Valve Phase II Replacement Project at the Truckee Meadows Water Reclamation Facility (TMWRF).

Petitioner/Presenter: John Martini, P.E. – Community Services Director/Michael Drinkwater, P.E. – TMWRF Plant Manager

Recommendation: Staff recommends City Council approve Sparks’ share of the contract between the City of Reno and HDR for a contract to design the Nitrification System Control Valve Phase II Replacement Project at TMWRF.

Financial Impact: There is no impact to the General Fund. There remains $578,321.49, contained in Fund 1631, Sanitary Sewer Capital Project Fund under Project 16-6590, TMWRF Projects for Year One, FY 2015-2016, of the 5-year Capital Improvement Plan (CIP) for the City of Sparks. Appropriations will be reallocated to support this continuing Fiscal Year 2013-2014 project. The City of Reno will enter into a reimbursement agreement with HDR Engineering, Inc. in an amount of up to $175,360.00 and will administer the project. Reimbursement will be sought from the City of Sparks for its share of expenses through the current cost sharing agreement for TMWRF capital projects, based on ownership of TMWRF, outlined in Attachment 1. Expenses will post to account 604090, TMWRF Construction, using CIP 14-6600C, TMWRF Nitrification Valves & Vaults Improvement Project.

Total Costs: $55,010.43

Agenda Item Brief:

City staff is asking that the City Council approve reimbursement to the City of Reno in the amount of $55,010.43 for its share of a $175,360.00 contract administered by the City of Reno with HDR Inc for the design of the Nitrification System Control Valve Phase II Replacement Project at TMWRF.

Background:

The control valves for the Nitrification Trickling Filters (NTF) must be operated at least twice per week as part of a snail mitigation treatment procedure critical to the operation and maintenance of the NTFs and TMWRF’s operation. The filters can only be taken offline for 4 to 6 hours at a time. Most of the valves do not have motor actuation, and can be difficult or time consuming for staff to operate. Several of the control valves are presently direct buried and operational difficulties are being encountered which includes leakage when closed. Some of the flow meters associated with the NTFs and nitrogen removal process do not currently operate or are not accurate. This project is being completed in two phases. The first phase addressed the most critical valves. The current proposed work (Phase II) will continue the work from Phase I and address the remaining valves and meters.

Analysis:

This consultant contract with HDR Inc. is for the design of Phase II of the nitrification tower control valves and related equipment. The City of Reno will administer the contract and will be reimbursed for a portion of the costs by the City of Sparks through the Sparks – Reno cost sharing agreement for TMWRF. The City of Reno and the City of Sparks share the cost for this project based upon their ownership of TMWRF, which is 68.63% for Reno and 31.37% for Sparks. Based on the ownership percentages, Reno’s share is up to $120,349.57 and Sparks share is up to $55,010.43.

Alternatives:

N/A

Recommended Motion:

I move to approve the reimbursement to the City of Reno for Sparks’ share of the engineering services by HDR Inc. in the amount of $55,010.43.
