AGENDA TITLE: Approve Plans and Specifications and Authorize Advertisement for Bids for
White Sough Water Pollution Control FaciNty Phase 3 Improvements
Project 2007, and Authorize the Pre -Purchase of Aeration Panels {5609,029}
MEETING DATE: January 17, 2007
PREPAFKD BY: Public Works Director
RECOMMENDED ACTION: Approve plans and specifications and authorize advertisement for
bids for White Slough Water Pollution Control Facility Phase 3
Improvements 2007, and authorize the pre -purchase of aeration
panels ($609,029).
BACKGROUND INFORMATION: The City has made substantial progress on the State -mandated
improvements at the White Slough Water Pollution Control Facility.
Phase 1 — Interim Aeration Improvements and miscellaneous
electrical and earthwork improvements was completed in 2003.
Phase 2 — Year 2004 Improvements Project, which was completed in 2006, included the installation of
tertiary filters, LIV disinfection equipment, additional aeration improvements, emergency generator, and
associated electrical and mechanical facilities. The condition of the trunk sewer between Lodi and the
treatment facility is being evaluated and preliminary indications are that a substantial rehabilitation will
need to be done relatively soon, and this cost can be considered as part of this financial work.
Council is being asked to approve the plans and specifications and authorize advertising for bids for the
Phase 3 project, which includes the construction of an additional secondary clarifier, an additional
digester, aeration basins, headworks modifications, minor administration building modifications, and
associated electrical, mechanical, utility, site preparation and demolition work. The improvements to the
secondary process are necessary to meet current and anticipated State of California regulatory
requirements and improve treatment process reliability. A prequalification process is included to
determine eligible bidders and ensure contractors have the necessary experience to perform the work.
Aeration panel pre -purchase — The aeration panels are to be installed in the two new aeration basins to
match the existing panels. The equipment purchase from Parkson Company as part of the Phase 2
project included a clause for the City to purchase additional aeration panels to be installed with the
Phase 3 project. The total cost of these panels is $609,029. Pre -purchase is necessary to insure the
panels are delivered and available for installation by the construction contractor to meet the project
schedule. We also anticipate a slight cost savings in purchasing these directly rather than through the
construction contractor.
The plans and specifications are on file in the Public Works Department.

FISCAL IMPACT- This project will be funded by the Wastewater Fund using the remaining
2004 Certificates of Participation (approximately $14,000,000) and another
financing to be completed after the project award when the project costs
are known. This third wastewater financing (matching the three
construction project phases) was planned in 2004. The financial analysis and rate increases in 2004 and
2005 covered these anticipated costs. However, once we receive bids and have a better cost estimate
on the pipeline rehabilitation work, we will be able to assess the potential impact on rates.
FUNDING AVAILABLE: Aeration Panels ($609,029) - Wastewater 2004 Certificates of Participation
Project Estimate: $28,185,000 (includes pre -purchased
equipment, construction administration services,
construction contract, testing and inspection and
other project -associated expenses)
