As a consequence of recent EU Directives and a substantial increase in
the environmental awareness of the general public, practising enginee
rs and researchers are now more than ever required to collaborate to p
rovide the higher standards of water quality being demanded. The engin
eers role is to implement a cost effective, practical and sustainable
solution; the researcher must provide the engineer with the tools and
'know how' to allow this solution to be attained. Recent research ende
avours in the UK have resulted in a philosophy known as Urban Pollutio
n Management. This philosophy allows the engineer to solve a drainage
catchment problem utilising either simple or complex approaches, depen
ding upon the ability of the receiving watercourse to assimilate disch
arges from CSOs and WTP's. The backbone of the complex approach is the
sewer flow quality model. Consequently for a 'realistic' solution to
be implemented, the sewer flow quality model must represent reality ac
curately. Work carried out in the City of Perth, has shown that there
are significant limitations to the accuracy of a typical sewer now qua
lity model; limitations which cannot be attributed to the mathematics
or the limitations of the particular package, but are due to the compl
exity and diversity of the phenomena encountered within sewerage syste
ms, particularly the effects of the sediments. This paper questions wh
ether in fact the recent UK research endeavour has actually provided e
ngineers with a tool/philosophy which can provide cost effective, prac
tical and sustainable solutions to complex drainage catchment problems
