Evaluation of Water Distribution Network Reliability
Introduction
Water distribution systems play a vitally important role in preserving
and providing a desirable life quality to the public. It has
been in the past that much of the effort in the design of water distribution
systems emphasizes on the aspect of least cost. The amount
of effort and attention given to develop a procedure for system performance
reliability evaluation has not attained a comparable scale.
Realizing the fact that many of the aged infrastructures in our communities,
including a water distribution system, have been deteriorated
to the point that their serviceabilities have drawn much attention.
There has been a growing awareness that it is equally important to
have a public water distribution system possessing a high service
reliability. There is very little work done in attempting to quantify
the system reliability of a water distribution network. This paper
reviews and applies some techniques which were found potentially
applicable for evaluating water distribution network reliability
(Billinton and Allen, 1983; Ang and Tang, 1975).
