Our environment

We provide both an essential service and have a key role in managing the water cycle to support community health and protect the environment.

With an eye to the future our Environment Policy commits us to care for and where possible, enhance the environment.

A strong commitment to protecting the environment is reflected in our environmental management system. Improved environmental performance can be achieved in a manner that satisfies customers’ expectations for community benefit and affordable services.

Reducing the resources we require to deliver our services and leveraging innovative technologies are key elements to achieving these requirements.

We hold certification to the international environmental standard ISO14001:2015.*

We continually strive to minimise business impacts on the environment. Consulting with our community on their expectations of our environmental performance, we developed our latest Environmental Sustainability Plan (ESP 5).

The plan contains a range of targets, aligning to our Corporate Strategy and reflecting our environmental risks and customers’ expectations.
