Site work for a water / sewer project in Great Falls, Montana. Conceptual plans call for site work for a water / sewer project.

The City of Great Falls is seeking proposals from highly experienced professional Consulting firms to compose a Sanitary Sewer System Capacity Model. The purpose of this project is to generate a master sanitary sewer hydraulic capacity model for the Citys entire sanitary sewer collection system including all sanitary sewer mains and lift stations. The City's preference would be to utilize Autodesk Storm and Sewer Analysis (SSA); however the Consultant shall compare alternative modeling programs and recommend modeling software best suited for the City considering ease of use and cost. This hydraulic model shall be turn-key and contain a GIS-compliant format that the City can access, maintain, and continue to operate and maintain in-house. The Consultant shall build the model utilizing the Citys existing sanitary utility mapping data, as-built drawing records, City's sanitary sewer master plan, and Lidar data. It is expected that the Consultant will need to acquire more data through research and field investigation. The Consultant is to calibrate and validate the model while taking into account dry and wet weather conditions. The Consultant shall provide training for City staff on the modeling software and the operation and maintenance of the hydraulic model. A final report shall be delivered detailing the creation of the hydraulic model and include: an evaluation of the existing system's capacity, identification of system capacity deficiencies, and model maintenance manuals and copies of all training materials.
