Explanation
1. BACKGROUND: This legislation authorizes the Director of Public Utilities to modify (Mod #2) a professional engineering services agreement with ARCADIS U.S. Inc. for the Sewer System Capacity Model Update 2012 Project for the Division of Sewerage and Drainage. The initial contract covered work for the first year with four subsequent annual contract modifications planned. This modification is needed to perform model applications, monitoring and data management, refinement of the sanitary model, stormwater model, real time control and system operation, deliverables and Blueprint Columbus Integrated Plan support.
The sewer collection system model developed and enhanced by the Model Update Project, is the principle tool used to manage the planning and operations of the City’s sewer collection system. Enhancement of this tool is vital to minimizing sewer overflows and backups and thereby minimizing negative impacts to the environment caused by the City’s sewer system. The continual updating of this model is also necessary to ensure compliance with the City’s consent orders with the Ohio Environmental Protection Agency.

• Review and utilize current Inflow/Infiltration study reports and SWMM 5 models (where applicable)
• Perform rain gauge: review, data collection/editing and rainfall analysis
• Perform flow monitoring: review, data collection/editing and dry/wet weather flow analysis
• Develop improved methodology for representing groundwater in the models
• Update dry weather flow patterns and time series
• Perform dry weather flow calibrations
• Update wet weather Rainfall Derived Inflow Infiltration (RDII) analysis (e.g. RTK, Initial Abstraction, Recovery parameters)
• Perform wet weather flow calibrations, and verification/validation
• Perform field investigations
• Enhance City GIS sewer attribute data as needed
• Prepare and deliver various technical reports and memorandum
• Deliver all collected flow monitor and rainfall data
