Sewer Flow Estimating Model (SFEM) is used in the planning process to manage sewers inventory where the results can be communicated to City management and community members. The general methodology developed to assess the sewers hydraulic needs is based upon defining the service area of the sewers and all wastewater contributors within that area. This uses groundwater infiltration, existing population and projected growth rates, and permitted industrial discharges to estimate existing and future wastewater generation. Since this information is geographically referenced data, SFEM was developed to quickly and accurately provide estimates of wastewater generation. This paper is on the flow estimating tool developed to analyze the hydraulic capacity of the sewer system. This tool has a population projection and distribution module, basin definition module, flow estimating module and flow accumulation module allowing users to estimate wastewater flows at anywhere in the collection system any time up to the year 2090.
