Integrated water cycle management

A 30-year IWCM Strategy addresses the complex linkages between elements of the urban water cycle (water supply, sewage and stormwater) and community expectations. This is done within the urban area and between its water related physical and legislative operating environment. This multi-level approach enables cost-effective integration of these urban water systems in consultation with the local community.

Integrated systems often rely less on limited natural water sources, produce less pollutant loads to the environment, have strong pricing signals and demand management measures. They encourage water conservation and efficient water use, enable the implementation of cost-effective recycling of treated effluent and urban stormwater use options and satisfy the water-sensitive urban design and 'liveable cities and towns' objectives.

The 30-year IWCM Strategy ensures that  any necessary capital works projects are appropriately sized and is essential for the provision of appropriate, affordable, cost-effective urban water services that meet community needs and protect public health and the environment.

A water utility's 30-year IWCM Strategy, developed using a transparent evidence based analysis in accordance with the IWCM Check List [link], identifies the integrated water supply, sewerage and stormwater scenario that provides the best value for money on the triple bottom line (TBL) basis of social, environmental and economic considerations.

The IWCM Strategy effectively provides an Options Report for any dams, water and sewage treatment works and recycling projects considered will streamline the subsequent section 60 approval of the project by addressing Steps 1 and 2 of section 60 approval process (1. Initial consultation and 2.Options Report). The IWCM Strategy identifies the function, capacity, likely technology, the capital cost of the project and the required typical residential bill for each of water supply and sewerage. The subsequent development of the project would therefore continue with Step 3 - Concept design and further environmental impact assessment.

The adopted scenario from the final IWCM Strategy defines the local water utility's 30-year Total Asset Management Plan (TAMP) and includes a 30-year Financial Plan (FP).

Local water utilities and their consultants should continue to use the remaining five IWCM Information Sheets listed below, until they are updated to better align with the IWCM Check List (PDF, 223.04 KB).
