How Rapid Growth in Fort Mill Necessitated Evaluation of New Treatment Technologies

The Fort Mill Water Pollution Control Plant (WPCP) is nearing the design capacity of its exsting secondary treatment system, with influent TKN loading approaching 90% of the design loading. At the same time, rapid growth projections in this suburb of Charlotte, North Carolina correlate to a tripling of influent flow/load in the next thirty years. This presentation will discuss the recent long-term planning and capacity evaluation undertaken for the Fort Mill Water Pollution Control Plant (WPCP), which focused on evaluating new treatment technologies against more conventational treatment technologies, in an effort to meet the current drivers for expansion (i.e. incrased flow/load) as well future drivers that include limited hydraulic capacity, more stirngent effluent total phosphorus limits, and limited available site footprint for expansion.
