Water Quality

Update: 5 February 2021

In response to the increasing discoloured water complaints which appears to be isolated to Blayney township, CTW advises that a large number of samples have been taken from a multitude of locations over the past week, to better understand why this issue is occurring.

These samples, in conjunction with Blayney Water Treatment Plant samples, show an increase in mineral content being sourced from the Lake Rowlands Dam.  As such, CTW is currently undertaking a vigorous flushing program of all its pipelines and making adjustments to our Blayney Water Treatment Plant to alleviate this issue. Whilst the CTW samples do not exceed the Drinking Water Quality guidelines, i.e. the water is safe to drink, the side effects of mixing one of these minerals (manganese) with chlorine has created this discoloured water issue.

CTW advises its Blayney consumers not to wash their “whites” until a full flush of all pipelines and its Treatment Plant adjustments have been completed. This is expected to be completed by early next week.

CTW apologies for the inconvenience that this issue has created to its Blayney consumers.

Drinking Water Guidelines

Central Tablelands Water has a comprehensive testing regime to ensure that water quality meets the required standards. We use standards set out in the Australian Drinking Water Guidelines, which are based on drinking water guidelines developed by the World Health Organisation. We also cooperate with the NSW Department of Health in our management of water quality.

Testing is carried out regularly. This testing regime helps to build up a history of water quality and identify any problems within the system. Common tests include E.Coli and total coliforms bacteria, pH, temperature, colour, turbidity, fluoride, chlorine, aluminium, iron, manganese and hardness.

Water quality programs are implemented to ensure that reticulated water meets the National Health and Medicine Research Council (NHMRC) guidelines, as well as to ensure that it is free from disease causing micro-organisms.

Water quality testing

We monitor and maintain water quality from the catchment to the tap. An independent laboratory undertakes testing.
Water quality results below contain results of water testing undertaken during the last 12 months.
