Chapter 3: Drinking water quality performance
Legislative requirements
The supply of safe and reliable drinking water in Queensland is regulated by various state legislation, including the Water Supply (Safety and Reliability) Act 2008 and the Public Health Act 2005.
Under the Water Supply (Safety and Reliability) Act 2008, a drinking water service provider may only carry out a registered drinking water service in accordance with an approved Drinking Water Quality Management Plan (DWQMP).
Under the Public Health Act 2005, Queensland Health has regulated the standards for drinking water quality related to E. coli and fluoride. These standards, together with the health guideline levels in the ‘Australian Drinking Water Guidelines 2011’ – updated May 2019 (ADWG), have been incorporated under the Water Supply (Safety and Reliability) Act 2008 as water quality criteria for drinking water in Queensland.
Gympie Regional Council has a well-constructed operational monitoring program and a summary against the ADWG is outlined below.
Water quality performance summary
For the 2019/20 reporting period, Gympie Regional Council met the prescribed microbiological standards for seven of the eight drinking water schemes.
Five of the eight water schemes complied with all of the health-related chemical limit values defined in the ADWG. The exceptions were the levels of trihalomethanes (THMs) at Amamoor, Imbil and Kandanga Water Treatment Plants. Events such as bushfires and flooding events following long periods of drought may increase organic load in source water, and subsequently, THMs in the distribution system. Increasing chlorine dose to deal with higher source water turbidity also resulted in elevated THMs.
Drinking Water Quality Management Report 2019/2020 Page 9 of 78
Table 1 summarises how our drinking water schemes performed over 1 July 2019 to 30 June 2020, against each category of water quality performance:

Table 1: Drinking water performance summary: 1 July 2019 – 30 June 2020
Verification monitoring program
To verify that we deliver safe drinking water, Council’s Environmental Health Department collects samples from the respective networks and sends the samples to a National Association of Testing Authorities (NATA) accredited laboratory for water analyses. These samples are collected from 31 dedicated sample points across the service region. The water quality data is reviewed and compared against prescribed requirements in the legislation and the ADWG.
As part of our commitment to continuous improvement we revise the location of the sample points in the network and install new sample taps with dedicated service lines if required.
Microbiological assessment (E. coli)
The standard for drinking water in Queensland requires no detection of E. coli in 98 per cent of samples collected over a 12-month period, as detailed in the Queensland Public Health Regulation 2005 Schedule 3A. Over 2019/20 seven of the eight drinking water schemes achieved compliance with the legislative E. coli requirements.
Kandanga water scheme had a result of 56cfu/100mL on 3 December 2019. Following investigations at the site, it was identified that the cause of contamination was a plastic hose connector attached to tap which was removed. After the installation of a new sample tap, a retest was conducted on 5 December 2019 which returned a result of 0 MPN/100mL.
E. coli water quality compliance details are provided in Appendix A, including the month-by-month performance.
Drinking Water Quality Management Report 2019/2020 Page 10 of 78
Health-related chemical assessment
We use a risk management approach to drinking water quality which allows us to identify the substances that may pose a risk to public health. The verification monitoring program analyses these substances which are continuously assessed against ADWG health-related limits and operational control triggers.
Five of the eight water schemes complied with all of the health-related chemical limit values defined in the ADWG. The exceptions were the below levels of trihalomethanes (THMs):
Water supply Date THMs (mg/L) range
Amamoor 9 December 2019 – 1 April 2020 260 - 330
Imbil 5 February 2020 280
Kandanga 3 April 2019 – 1 April 2020 300 - 440
Table 2: levels of THMs
THM monitoring has been established and will be maintained to manage the performance of the water schemes. If an operational target is exceeded, there may be an increase of sampling frequency to obtain a more comprehensive understanding of THM concentrations in the distribution system. The aim is to collect data for long-term evaluation of THM performance and improvement. The relationship between chlorine dose and THM formation has been examined.
Health assessment water quality compliance details are provided in Appendix B.
Aesthetic assessment
Our routine verification monitoring program is important for us to verify that we provide safe drinking water to our customers. We take advantage of the program to continuously assess non-health related parameters which contribute to the way our water tastes, smells and appears. We aim to meet the ADWG aesthetic guidelines where possible, however providing safe drinking water is our overriding priority.
Drinking Water Quality Management Report 2019/2020 Page 11 of 78
Chapter 4: Notifying the regulator Under sections 102 and 102A of the Water Supply (Safety and Reliability) Act 2008, Gympie Regional Council is required to immediately inform the Regulator if the quality of water supplied from its drinking water service does not comply with the water quality criteria as specified in the ADWG.
In the event that Gympie Regional Council becomes aware of a reportable incident, we notify the Regulator within the required timeframe.
On detection of a water quality issue, Council will:
• initiate further sampling in the affected zone
• undertake a comprehensive investigation to determine the factors that may have attributed to the event, and
• initiate responsive corrective actions e.g. flushing of water mains.
For the 2019/2020 year the reportable events were:
• THM exceedances in Amamoor water scheme between 9 December 2019 and 1 April 2020 with a range of 260 and 330 ug/L
• THM exceedance in Imbil water scheme on 5 February 2020 with a value of 280 ug/L
• THM exceedance in Kandanga water scheme between 9 December 2019 and 1 April 2020 with values ranging from 300 and 440 ug/L
• E. coli exceedance at Kandanga water scheme on 3 December 2019 with value of 56cfu/100mL. A retest was undertaken on 5 December 2019 returning value of 0.
We are reporting THM results on a monthly basis to the Regulator to enable a collaborative long-term evaluation of THM performance.
Drinking Water Quality Management Report 2019/2020 Page 12 of 78
Chapter 5: Managing water safety Gympie Regional Council is committed to providing safe, reliable drinking water from source to our customers’ tap. We ensure a consistent and reliable supply of high quality and safe drinking water to our customers through a risk management and robust planning approach.
Drinking Water Quality Management Plan review
Gympie Regional Council operates with an approved DWQMP that is reviewed every two years. As a result of the last review in December 2019, a DWQMP amendment was submitted to the Regulator and was approved on 20 March 2020. The DWQMP follows industry best practice in that all water quality hazards have been identified, risk assessed, and commitment made to implement necessary improvements.
Council has implemented new processes to ensure all sampling is undertaken in accordance with its DWQMP. Council has also reviewed and improved its procedures to ensure data collection and reporting is accurate. This includes the below instrumentation upgrades.
Instrumentation upgrades Gympie Regional Council operates nine reticulated water networks (note, Cooloola Cove/Tin Can Bay is one water scheme). The operations are supported by the Supervisory Control and Data Acquisition (SCADA) network and multiple SCADA solutions. Council’s intention is to have a robust and reliable SCADA system across the region to monitor and operate its assets.
During the 2019/20 reporting period, there were a number of installations of new online instrumentation to provide controls (CCPs) that ensure the parameters within the DWQMP are achieved at the below sites:
• Cooloola Cove Water Treatment Plant
• Jones Hill Water Treatment Plant, Gympie.
• Kilkivan Water Treatment Plant
• Rainbow Beach Water Treatment Plant.
New water treatment plants – Amamoor and Kandanga
The new water treatment plants for Amamoor and Kandanga were operational in late 2019. These new plants utilise enhanced treatment processes such as ultraviolet disinfection along with standard industry best practice filtration and chlorination steps.
Drinking Water Quality Management Report 2019/2020 Page 13 of 78
Goomeri water supply scheme
On 15 June 2020, work commenced at Goomeri Water Treatment Plant to replace the media in the filters. Media in both the sand filters and the activated carbon filter (used to remove taste/odour) was successfully replaced and the plant came back on line on 17 June 2020.
The plant was configured to treat surface water and the raw water source gradually shifted to use surface water from Kinbombi Weir. This became the sole source of supply on 6 July 2020.
The turbidity and colour of the water increased as the percentage of surface water has increased, while the hardness and salinity has correspondingly decreased.
Drinking Water Quality Management Report 2019/2020 Page 14 of 78
Chapter 6: Managing the customer's water quality experience Gympie Regional Council receives various water quality enquiries throughout the year. When a customer is dissatisfied with the efforts of Gympie Regional Council to address a water quality issue and remedial action is required, these enquiries are classified as 'water quality complaints'.
Water quality complaints are captured, recorded and monitored to help identify any trends and possible areas of improvement in the operation, maintenance and management of the Gympie Regional Council water supply network.
In 2019/20, Gympie Regional Council received six water quality complaints. These complaints included concerns about:
• chemical content of water supply in the Rainbow Beach water scheme
• colour of water supply in Gympie water scheme
• hardness of water supply in Goomeri water scheme
• taste and quality of water supply in Kandanga water Scheme
These concerns were all investigated, customers were contacted and matters resolved.

Chapter 7: Risk management improvement program update A review of our risk management improvement program was conducted in December 2019. The below dot points outline the progress against this risk management improvement program and include:
• A program of works that has been developed to remove cross connections, install air
gaps and remove bypasses to ensure untreated water is not supplied to the network
• A program of works that is being developed to install new sample taps and service lines to ensure sample integrity
• Commencement of the implementation of the SCADA strategy to upgrade all sites to ClearSCADA and an overarching IP WAN secure network
• Commencement of a multi-year project for the installation of additional water quality instrumentation to provide “online” monitoring and alarming across the eight WTPs. This project will ensure that every plant follows industry best practice, with the implementation of automation and enable real time monitoring of critical control points.
