Description/Analysis
IssueDetail
Issue Detail: Staff recommend City Council award a construction contract to TNT Industrial Contractors, Inc., to rehabilitate the E.A. Fairbairn Water Treatment Plant (FWTP) grit basin. The project scope includes: removal and replacement of the clarifier rake arm, recoating of center pier, replacement of access ladder, and installation of safety access gate to ladder.
Given that the FWTP grit separator is only accessible during short annual shutdowns and is essential for water production, staff recommends council approve increased authority for construction change orders up to $150,000 to address any unforeseen conditions that may arise during rehabilitation. This increase will help ensure that any critical repairs can be completed within the limited shutdown window, preventing delays in bringing the water treatment plant back to service.

PolicyConsiderations
Policy Considerations: City Council approval is required for contracts of $250,000 or more per City Code 3.56.090. The action requested conforms with City Code Chapter3.56, Articles I and III, which provide for award of competitively bid contacts to the lowest responsible bidder. This project is also consistent with the 2040 General Plan Policy PFS-4.3 to rehabilitate, replace, and expand critical infrastructure to ensure reliability and safety.

EconomicImpacts
Economic Impacts: This project is expected to create 1.56 total jobs (0.9 direct jobs and 0.66 jobs through indirect and induced activities) and create $240,706 in total economic output ($151,719 of direct output and another $88,987 of output through indirect and induced activities).
The indicated economic impacts are estimates calculated using a calculation tool developed by the Center for Strategic Economic Research (CSER). CSER utilized the IMPLAN input-output model (2009 coefficients) to quantify the economic impacts of a hypothetical $1 million of spending in various construction categories within the City of Sacramento in an average one-year period. Actual impacts could differ significantly from the estimates and neither the City of Sacramento nor CSER shall be held responsible for consequences resulting from such differences.

EnvironmentalConsiderations
Environmental Considerations: The proposed activity has been determined to be exempt from the California Environmental Quality Act (CEQA) pursuant to Section 15301 and 15302 of the CEQA Guidelines governing existing facilities and replacement or reconstruction. The activity consists of the operation, repair, and maintenance of existing facilities including the restoration or rehabilitation of deteriorated or damaged structures, facilities, or mechanical equipment to meet current standards of public health and safety; and the replacement or reconstruction of existing utility systems and/or facilities involving negligible or no expansion of capacity.
End
Sustainability
Sustainability: The proposed project is consistent with the 2040 General Plan Goal PFS-3.5 Water Treatment Capacity and Infrastructure as it improves infrastructure reliability, which will ensure continued safe operation and maintenance of the existing facility.

Background
Background: The clarifier rake arm assembly for the grit basin at FWTP is the original equipment that was installed in the 1960s. In 2020, water treatment plant staff replaced failing bolts on the equipment to keep the equipment in operation. An in-depth structural analysis was performed by a structural consultant in 2022 to assess the structural integrity of the rake arms. It was determined that the coating on the equipment had failed and substantial material loss in structural members had occurred due to corrosion. The installation of new stainless steel rake arms will provide an expected service life of approximately 30-50 years with proper maintenance, significantly improving long-term reliability.
All water from the American River intake moves through the FWTP grit basin prior to being treated to drinking water standards. It is a single basin designed to collect and remove heavy solids and sediment before the solids can move into the next step in the treatment process. Ensuring that this facility stays in operation improves the effectiveness of the treatment process due to the higher amount of heavy solids that won’t have to be treated further down in the system.
