An updated hydraulic model is an invaluable tool for water and sewer utilities. With a well calibrated and accurate model, utilities can simulate system performance under varying conditions, pin-point problem areas, test proposed improvements, and identify future projects. As systems age and demand fluctuates, a functional system model will prove to be a crucial tool for inventory management, risk management, capital planning, and maintenance strategy. Using examples from a variety of past modeling projects, this presentation will provide an overview of the asset management benefits of hydraulic modeling. We will discuss different hydraulic modeling software and best practices for each. Additionally, we will cover the information required from the utility for developing a system model from scratch. Lastly, we will highlight the importance of maintaining and updating the hydraulic model as major system improvements are made. A presentation outline follows: •Model Development oEPS vs Steady-State oModeling demand allocations (planning zoning) oGIS Integration oSoftware oAssumption development, and how these limitations impact the model analysis •Model Applications oDesign ?BPS ?Pipe Sizing oRegulatory approvals oCapacity development, understanding availability for potential demand users ?Kentucky and Tennessee are experiencing huge economic growth which can lead to large new demands in previously rural areas oEmergency connections, potential system availability oCriticality modeling, understand how potential line segments impact the Utility oAssistance during major breaks oImprove pressure zone delineation (planning) oTank turnover oWater Age oDistribution allocation to wholesalers for rate analysis A well-developed hydraulic model can assist utilities in responding to a wide range of issues from planning initiatives to emergency response. This presentation will provide insights into hydraulic models and provide practical examples for utilities to implement.
