WIOA welcomes contributions from any persons or organsiations which can be used as a resource by operational people in the water industry to improve their efficiency, knowledge or skills.

Value of Operator Competency

A study to demonstrate the value of developing, building and continually growing a competent operator workforce.

The Value of Operator Competency project aimed to identify and communicate the value and benefits of an appropriately trained and competent frontline operator workforce. The ability of a frontline operator to capably and competently manage water quality safety risks is extremely important to public health and safety, and environmental outcomes.

Guide to the measurement and use of Ct

Disinfection of water (potable or recycled) with a chemical disinfectant (chlorine or chloramine) requires time for the chemical to react with and kill the target microbial pathogens. Ideally the time for the reaction is provided in a purpose-built reactor or contact tank as this is specifically designed for this purpose and provides a controllable process. The reality however is quite different. Most water supplies rely on disinfection to occur in clear water tanks and reservoirs of various size, with various arrangements of inlet and outlet structures and varying levels of short circuiting. The effective contact time is often less than is assumed.

Many water utilities use a target free or total chlorine residual in their treatment systems to achieve a level of disinfection that they understand to be adequate. This approach to disinfection can be improved in most cases.

Water Industry Technical Competency Handbook

The Technical Competency Handbook has been developed to assist water utilities to develop processes and practices designed to deliver a technically competent water industry operational workforce. Approaches for planning and delivery of learning and development (L&D) programs to achieve technical competency, as well as to manage ongoing professional development along with examples and case studies are presented.

This handbook is primarily aimed at the quality & risk management, as well as technical knowledge and skill requirements of water industry operations staff. Together, these two areas form the basis of key technical competency requirements for operations. This is beyond the fundamental business systems knowledge and workplace health and safety training and skills, which are essential for all staff working in the water industry.

Australian Drinking Water Guidelines

The Australian Drinking Water Guidelines (ADWG) have been developed by the National Health and Medical Research Council (NHMRC) and undergo rolling revision to ensure they represent the latest scientific evidence on good quality drinking water. As sections of the Guidelines continue to be reviewed, this page will be updated to provide the latest information.

The guidelines have been developed after consideration of the best available scientific evidence and provide a framework for good management of drinking water supplies to ensure safety at point of use. They address both the health and aesthetic quality aspects of supplying good quality drinking water.

Australian Guidelines for Water Recycling

Managing Health and Environmental Risks

The Australian Guidelines for Water Recycling: Managing Health and Environmental Risks (Phase 1) provides a generic ‘framework for the management of recycled water quality and use’ that applies to all combinations of recycled water and end uses. It also provides specific guidance on the use of treated sewage and greywater for purposes other than drinking and environmental flows.

 Australian Guidelines for Water Recycling: Managing Health and Environmental Risks (Phase 1)

Augmentation of Drinking Water Supplies

The Australian Guidelines for Water Recycling: Augmentation of Drinking Water Supplies (Phase 2) extends the guidance given in Phase on the planned use of recycled water (treated sewage and stormwater) to augment drinking water supplies.

The document focuses on the source of water, initial treatment processes and blending of recycled water with drinking water sources.

Protect our Waters, Protect our Health Brochure

The Victorian Department of Health have developed a brochure Protect our Waters, Protect our Health highlighting the importance of preventing stock access to natural waterways. Protecting the environment, including our waterways (rivers and streams), is a responsibility shared by government, industry, businesses, communities and individuals. Landholders, in particular, have a responsibility to manage their activities to avoid polluting waterways.

Review of high pressure water jetting components in the MSM Manufacturing Training Package.

The focus of this project is:

  • review of the 4 units coded MSMWJ
  • review of the 4 high pressure water jetting skill sets

As part of the review, there has also been a recommendation to develop a new unit of competency for hydro excavation. To ensure the training package components have strong links to the industry feedback on the updates that are proposed are sought.

Please send any feedback by Friday 26 June to Mark Shaddock-

Water Treatment Analyser Tools

 Water Treatment Analyser Article from Operator Newsletter (96kb)

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.

Instructions for use:

  • Select the Analyser from the links below
  • Select “Save” and navigate to your preferred folder location, and select Save.
    Do not change the workbook name.
  • Close MS Excel.
  • The tools must be opened from MS Excel and not from file manager.
  • Start Excel. Go to File/Open, navigate to the saved file location and select the file. Click on open.
  • Follow the on-screen instructions to use the tools.


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.

WTPO Helper

As a water treatment operator Michael Fawcett from South Gippsland Water identified the need for an app to assist with dosing room calculations, either when changing the dose rate mg/L or working out the dose rate from the mL/min taken from the drop test. The idea was driven by his desire to do away with pens and paper and have the timer and the calculator right in his pocket.

The WTPO Helper app includes 15 calculations and 4 useful data loggers used in the day to day data collection operations of Water and to a lesser degree wastewater plant. Our jobs require a large amount of data to be recorded and the WTPO Helper has some useful tools to make this easier for operators.

The Calculations
• Chlorine Gas Feed Rate
• Solution Chemical Feed Rate
• Chloramination Ratio
• Dry Chemical Feed
• Dosing Solution Strengths
• Jar Test Solution Make Up
• Detention/CT Times
• Total Suspended Solids
• Total Dissolved Solids
• Maintenance Mains Volume Calculations

The Data Loggers
• Drop Test Timer and Logger
• Meter Logger
• Flushing Timer and Logger
• Dam Surveillance Timer and Data Logger

Download the free app for Android on Googleplay and from the Apple store for the iPhone or iPad.
