Water Supply Networks

There are 3 water supply networks in the Narromine Shire. Narromine, Trangie and Tomingley's drinking water is sourced from a range of bores.

Monitoring Water Quality

Council has a comprehensive monitoring and testing program to ensure the safety of the drinking water. Regular water samples are collected and tested from water sources, treatment plants and pipe networks. These tests look at microbiological and chemical levels that can affect customers’ health, as well as aesthetic physical quality levels that can affect the taste and colour of water.

Water Quality 

In 2024-2025, Narromine Shire Council performed routine drinking water sampling and testing to monitor the quality of drinking water. 

The results were submitted to the NSW Drinking Water Database by the NSW Forensic and Analytic Sciences Laboratory.

Compliance is determined against the Australian Drinking Water Guidelines (2011) guideline values for E. coli, physical and chemical characteristics of drinking water.

The Narromine supply system achieved compliance of 100% for physical, chemical, and microbiological samples.

The Tomingley supply system achieved compliance of 80% for physical, 100% for chemical, and 100% for microbiological samples.

The Trangie supply system achieved compliance of 87.5% for physical, 100% for chemical, and 100% for microbiological samples.

Per and Poly-Fluoroalkyl Substances (PFAS)

PFAS chemicals or per- and poly- fluoroalkyl substances are synthetic chemicals found in many everyday products. They have been widely used in many industrial and consumer applications as they are effective at resisting heat, stains, grease and water. The National Health and Medical Research Council (NHRMC) has stated that drinking water supplies that comply with the current Australian Drinking Water Guidelines (ADWG) are safe to drink.

For further information about PFAS please refer to the fact sheet from the Water Services Association of Australia (WSAA): Per- and Poly-Fluoroalkyl Substances (PFAS) Fact Sheet

Council undertakes a regular sampling program of source and treated water for PFAS in accordance with the ADWG and NSW Health requirements.

The 2025 PFAS sampling results conducted by a National Association of Testing Authorities (NATA) accredited laboratory are presented below.

Due to elevated concentrations of PFAS within one of Narromine's source water bores, monthly PFAS sampling is currently in progress.

Tomingley and Trangie potable water systems have annual PFAS testing.

Council's treated drinking water is safe to drink and within Australian Drinking Water Guidelines.
