The objective of this service is to provide engineering for improvements to the sewerage system to operate the Park safely and cost-effectively. After years of continuous use and deterioration, much of the sewerage system requires repair and replacement. A conceptual improvement plan developed by the Park District is enclosed with this RFP. A condition inspection report for most of the gravity lines will be provided later in an addenda when it becomes available. The condition inspection report will identify elements of the gravity sewerage system in need of repair or replacement. The conceptual plan identifies a potential new sewer line alignment to replace the comminutor and syphon line which currently crosses sensitive habitat.
