PROOF OF CONCEPT APPROACH

摘要

INTRODUCTION There is an increasing need for water utilities to provide tangible evidence that targeted improvement measures in multi-use drinking water supply catchments can lead to reduced water quality risks and save cost, as compared to other improvement measures (such as water treatment upgrades). As a first step to canvass the potential success of introducing an accelerated stock exclusion program in a drinking water supply catchment, the Kersbrook Water Quality Improvement Project - Pathogen Reduction, considered the feasibility of implementing an accelerated pathogen reduction effort (primarily stock exclusion from watercourses) from two perspectives: the effectiveness of stock exclusion on water quality (in this case pathogen concentrations); and the ability to engage target landholders and realise an effect in a short timeframe.
