Abstract
A water quality evaluation of regional wastewater system centralization was undertaken to test the hypotheses that water quality improvement may result from the spatial and temporal variations of wasteloads attributed to decentralized regional systems. The evaluation employed water quality models developed for both deterministic and stochastic analyses. Each analysis considered a set of experiments which involved a determination of the water quality resulting from alternative degrees of regional wastewater aggregation. The experiments treated not only the degree of aggregation but also the stream system length as an indicator of regional morphology and the streamwater/wastewater dilution ratio as an indication of relative stream size. The water quality assessment was made in terms of the minimum dissolved oxygen level experienced by the system. Cost functions for regional wastewater system components were developed. A comparison was made between the water quality impact of various regional wastewater systems and the economic impact of these systems. It was concluded that substantial benefits, both economic and water quality, may result from decentralized regional wastewater systems.
