No design can be undertaken without proper planning, and no planning can take place without a thorough understanding of system dynamics through the creation and calibration of a true hydraulic model. CMA’s experience with hydraulic models goes back to the original KY Pipes modeling software. Today, CMA selects the appropriate model based on the desired analysis and client familiarity. Depending on the available information and desired outcomes, CMA has created steady state and extended period simulation (EPS) models inclusive of hydraulic information and water quality.
Recently, CMA completed a modeling project for Palm Beach County Water Utilities Department focused on the determination of system adequacy in terms of fire flow, water age, and minimum hydraulic performance conditions. The efforts completed included a summary of the existing potable water system facilities, water demand conditions evaluation, hydraulic model calibration efforts, hydraulic model results and evaluation, water quality evaluation, valve criticality assessment, and pipe break analysis of water main aerial crossings. Special conditions included evaluation of additional water demands for bulk users, and evaluation of water treatment plants (WTPs) out of service, and WTP area of influence. This system consisted of over 30,000 nodes and 35,000 pipes representing over 2,250 miles of pipeline.
