The breakeven point and global costs associated with the use of dispersed treatment units within a water distribution system to manage network-derived water quality degradation were investigated. Disinfection byproduct (DBP) formation was used as a representative water quality degradation parameter. A basic DBP formation model was used to predict exposure within a hypothetical water utility service population. The costs of upgrading centralized treatment facilities to meet DBP water quality standards were estimated and then apportioned over the fraction of residential service population receiving water degraded below required quality levels to estimate the breakeven costs for the alternative distributed treatment approach. Breakeven costs for a 10-connection treatment unit were calculated for a range of service populations. A sensitivity analysis of the impacts of various network parameters on breakeven costs revealed the existence of singularities - sudden shifts in optimal technology selection - resulting from relatively small variations in required treatment levels.
