Time‐averaging water quality assessment
A time‐averaging model is a fast, efficient way to continuously assess water quality in the distribution system.
While reauthorization of the Safe Drinking Water Act is pending, many water utilities are preparing to monitor and regulate levels of distribution system constituents that affect water quality. Most f requently, utilities are concerned about average concentrations rather than about tracing a particular constituent's path. Mathematical and computer models, which provide a quick estimate of average concentrations, could play an important role in this effort. Most water quality models deal primarily with isolated events, such as tracing a particular constituent through adistribution system. This article proposes a simple, time‐averaging model that obtains average, maximum, and minimum constituent concentrations and ages throughout the network. It also computes percentage flow contribution and percentage constituent concentration. The model is illustrated using two water distribution systems, and results are compared with those obtained using a dynamic water quality model. Both models p redict average water quality parameters with no significant deviations; the time‐averaging approach is a simple and efficientalternative to the dynamic model.
