Demand Management

Water demand management may be defined as managing the demand for water to achieve a balance between economic, social equity and environmental outcomes. Such programs incorporate measures that improve water use efficiency, offer the opportunity to reuse and recycle water and minimise water waste.

Effectively managing water demands involves:

  • understanding how and where water is used
  • consideration of the costs and benefits of each option and
  • development and implementation of a demand management program. 

From the perspective of Water Service Providers and their customers, a permanent reduction in water demand is identical to an increase in supply. By reducing demand, the costs of transferring and treating water are reduced and the capital investment required to meet the needs of growing communities can be deferred. 

From the perspective of the community and business, these lower operating and capital costs mean lower water bills, as well as lower energy bills resulting from reduced hot water use. The environment benefits from reducing extraction from rivers and aquifers leading to increased flows and improved river health. Lower energy consumption also leads to a reduction in greenhouse gas emissions. The community has a strong expectation that water is used efficiently and not wasted.
