Operations and Maintenance Manuals

qldwater has created a number of Operations and Maintenance Manuals (sometimes working collaboratively with the NSW Water Directorate) to assist members in forming their own internal O&M Policies and Procedures documents.

The following documents have been distributed to members:

A number of  Industry Factsheets that deal with different aspects of O&M have also been developed to assist members.

WIOA Resources Available

WIOA have provided a Guidance Note for On Line Turbidity Meters which  is available here -

Online resources - Water Treatment Analyser Tools are available on the WIOA website at An overview of the tools available is below.

Water Treatment Analyser

The Water Treatment Alliance and the Water Services Association, with support from the Victorian Department of Health, have developed some Excel based software tools to allow Water Utilities and Water Treatment Plant (WTP) operators to assess the performance of their plants at the two key control points for pathogen control, namely media filtration and chlorine-based disinfection.


The WTAnalyser allows you to download and extract data from SCADA trends for detailed analysis. Since the trending system samples at short time intervals, very large amounts of data make up the trends. The first step is to extract a subset of the data for further analysis.

Water Treatment Analyser Disinfection - Spreadsheet (v3.0 Excel Spreadsheet)


This tool has been developed to assist you in analysing the performance of filters at your plant. It extracts data from other MS Excel or csv files. Once data is selected it is automatically processed into a graphical and statistical format that will tell you how your filters are performing.
