Tank Paddock: A Comparison Between Traditional and Water Sensitive Urban Design

The objective of the study is to compare outcomes of innovative water sensitive urban design with more traditional methods of urban infrastructure. This comparative analysis is based on the proposed urbanisation of Tank Paddock. The authors wish to demonstrate how water sensitive urban design can mitigate developmental effects on adjacent wetlands.

Comparison of construction costs and performance for the two scenarios demonstrate compelling evidence to support the implementation of the water sensitive urban design option. The study shows a 53% reduction in construction costs, safer roads during large storm events and additional environmental benefits such as reduced erosion damage and contamination.

An Introduction to Water Sensitive Urban Design

This presentation introduces the concept of water sensitive urban design by firstly outlining the urban water crisis associated with traditional designs. For future sustainability, a change to water sensitive approaches must be implemented.

The presentation explores the adoption of water sensitive practices on different scales and illustrates this new era of water sensitive urban design.

Cost Benefits of Source Control Measures

This case study evaluates the economic benefits associated with source control measures implemented in regional Australia. Examples of source control measures include rainwater tanks, infiltration trenches, detention basins and constructed wetlands in residential areas. To examine their impacts, the case study explores the Lower Hunter region of New South Wales.

The report finds the effect of rainwater tanks to supplement water supply networks delayed the construction of new water supply headworks infrastructure by up to 34 years. Findings show a reduction in demands on water supply trunk systems, stormwater discharge and demand on household water mains. Source control measures provided the most significant benefit to the community.
