TMWRF utilizes 14 primary and secondary clarifiers in the wastewater treatment process.  These clarifiers are concrete tanks with steel mechanical rotating mechanisms and they range from 16 to 50 years old.  Over years of continuous operation, the concrete tank structures and mechanical equipment require repairs and rehabilitation.  Annual repair and rehabilitation of the clarifier basins is included in the Joint Coordinating Committee approved TMWRF Capital Improvement Program.  For the 2016 clarifier rehabilitation project the Primary and Secondary 1C Clarifier Basins were selected. 

The rehabilitation activities consist of repair of expansion joints, replacement of the steel roller wear ring, providing minor repairs to the grout beds, concrete walls and some portions of the steel hardware.  This work is considered necessary to prevent further deterioration of aging concrete structural components, which if not addressed could result in the need to replace the structure.

The City of Reno held an open, competitive bid to select the proposed contractor.  KG Walters Construction, Inc. was the lowest responsible bidder with a total project bid of $395,200.00.  Reno will continue to 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, Sparks’ share of this agreement is up to $123,974.24.  The cost split between Reno and Sparks is shown in Table 1, attached.

Council could direct the manager to have staff provide other alternatives.

I move to approve the reimbursement to the City of Reno for the Sparks’ share of the construction of the Clarifier Rehabilitation Project at TMWRF not to exceed $123,974.24.
