With the tightening of the ADWG requirements for filtered water turbidity and the increased focus on Protozoan removal from drinking water, filter inspections have become an important part of assessing the condition and capability of Water Treatment Plants (WTPs) to assure the production of safe drinking water. Prior to 2012 there was no systematic approach to carrying out filter inspections within North East Water (NEW) in Victoria. Some operators and work groups carried out filter inspections intermittently, but they typically were carried out as a reactive measure.
