Supporting water quality operations
Just a heads-up—this section is still a work in progress! I’ll be revising and expanding it soon to make sure it’s as useful as possible. Curious about what’s already done or currently in the works? Check the changelog for updates.
While a dedicated water quality model (as discussed in another chapter) is needed for detailed constituent analysis, your hydraulic model plays a crucial supporting role in many operational activities aimed at maintaining and improving water quality within the distribution system. This section will discuss how understanding the hydraulics — the flows and velocities — can help you plan and evaluate these operations more effectively.
For instance, one common practice is unidirectional flushing (UDF) to remove sediments and improve water clarity. Your hydraulic model can be used to design effective UDF sequences by simulating the flow velocities that will be achieved in different pipes, helping to ensure they are high enough to adequately scour the mains without causing undue pressure disruptions.
