Managing environmental risk is central to everything we do. Our Environmental Policy (PDF 709KB) outlines our long term approach to managing our water, sewerage and recycled water services.

To see how we're planning for drought, climate change and population growth in our region, see water security.


Sustainability strategy

As a water business, we face significant environmental challenges, including:

  • land management
  • climate variability
  • population growth
  • carbon emissions

Our Sustainability Strategy (PDF 383KB) highlights what we're doing to be more environmentally friendly and keep pressure off prices.


Biodiversity

Water and wastewater services affect biodiversity. As part of the overall Sustainability Strategy, our Biodiversity Strategy (PDF 100KB) outlines what we're doing to minimise our impact.


Threatened ecological communities

We use an ecological vegetation class (EVC) system to map vegetation communities and their conservation status in areas we plan to work. If communities are endangered, we explore all possibilities to avoid affecting these areas.


Water storages

The Coliban storages offer drought refuge for many fauna species. The arms of Lake Eppalock also offer wind protection and shallow water for wading and waterbirds.

But severe drought impacts on biodiversity, in particular, fish and any protocols used for fish kills, monitoring water quality, stratification and blackwater events.


River flows

Dams change the flow of rivers and can threaten the biodiversity of river banks. To understand the effects of developing our waterways, we participate in the Bulk Entitlement (BE) development process, led by the Department of Sustainability and Environment.

As a water corporation, the Minister for Water issues Bulk Entitlements to give us the legal right to take and use water. We review Environmental Flow reports prepared by scientific panels to look at the effect dams and bulk entitlements have on each river system.


Catchment protection

We manage 3 major supply reservoirs - the Upper Coliban, Lauriston and Malmsbury reservoirs - each contained in their own catchment. Our catchments are open, which means the land is privately managed by the rural community over many land titles.

We protect our regional water supplies through land management and community relationships outlined in our Drinking Water Storages and Land Management Plan (PDF 3.3MB).


Dam flooding

As part of our catchment protection policies, we have developed emergency management plans for dam safety and flood mitigation:
