Abstract
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 .
