A central treatment system would require a significant amount of infrastructure to move the untreated water from the various well locations to a central point and then back to the distribution system. HWSA anticipates that this approach would disrupt most of Horsham Township for an extended period of time. Individual GAC filtration systems can be installed much sooner than it would take to engineer and construct a central plant. Additionally, individual well filters are extremely efficient for the inevitable long-term maintenance needs of a water system. If one well requires maintenance, only that well would have to be taken offline with no disruption or inconvenience to residents.
