摘要：Extensive proportions of active water distribution
networks are situated in urban regions with very high service
demands that subject them to lots of external pressure. This
means that they are exposed to higher risks-of-failure. Within
urban regions, however, water pipelines are lined in different
city locations with varied risk levels. Pipelines are bound to fail
despite their location. Nonetheless, additional location
dependent risk elements may either heighten or lower the
failure process. In this paper therefore, we evaluate failure
trends of pipelines in a region characterized with two soil
types; regular and volatile Dolomitic grounds, outlining how
the different soil types affect water pipeline failures. We also
assess failure variations in two major pipe alignment zones
identified during the study. To achieve this, we used data from
a selected metropolitan region in South Africa and applied
Bayesian Networks to accommodate inherent data uncertainty
while modeling failure causal properties. Findings from the
assessment indicate that risk-of-failure is higher along exit
sections that experience additional external pressure.
