collective wastewater treatment facilities; exploitation cost; investment cost; Walloon Region
Abstract :
[en] This paper contributes to a better understanding of costs for collective wastewater treatment in
the Walloon Region (Belgium). Based on a large set of data, unit costs to population equivalents
are modelled. Considering investment as well as exploitation costs, the model includes not only
wastewater treatment plants but also collector and sewage networks in an integrated approach
at the technical basin level. Beyond this modelling, each type of process is analyzed
independently in order to explore the structure of investment costs and their variation factors.
Then, the model was used to forecast the upcoming expenses for 36 areas which are not yet
equipped with collective wastewater treatment facilities. In light of these results, strategic
choices for decision makers are discussed.
