Integrated Water Management Developers Guide

We're committed to collaborative planning using an IWM approach. As part of the land development process, we require developers to produce a Development IWM Plan.

The Development IWM plan must outline how the whole water cycle will be managed across the new development. The planning process brings together the water cycle management requirements of Greater Western Water, Melbourne Water and the local council into a single plan.

The IWM Developer Guidance outlines how a developer can meet these water cycle management requirements for properties in the area previously serviced by Western Water. It was developed in collaboration with authorities with a range of water responsibilities.
