Sanitary Sewer Projects - Fiscal Year 2006-2007
Secondary System Improvements Construction - $100,000
Construction of interim improvements to the secondary (biological) treatment system at the wastewater treatment plant will address short-term process limitations. Inadequate aerator tank capacity creates the potential for exceeding the plant's effluent limitations. Permanent process improvements will eventually incorporate these interim facilities.
Pump Station #4 Replacement - $65,000
Replacement of the 1960's-era pump station on River Forest Lane with a new submersible Pump Station.
Sanitary Sewer System Master Plan - $400,000
This project involves the creation of a new santiary sewer system master plan guiding OLSD future investment in the wastewater treatment plant. The OLSD treatment plant meets the current requirements, but the facility faces many future challenges, including a chlorine system that must be upgraded to current safety standards, a 60's era biological system with inadequate capacity to meet modern standards, and a highly-eroded gravity thickener. Additionally, the District faces new environmental regulations affecting the Willamette River, which may require renovation or improvements beyond modernization of the treatment plant's aging infrastructure. The master plan will identify the facility needs, develop solutions, and establish a correction plan. The OLSD Board of Directors will review and approve any master plan efforts.
Plant Renovation Design Service Phase 1 - $400,000
Money budgeted to begin implementing the improvements recommended through the Master Plan, pending its approval and creation.
