Zero Additional Maintenance Water Sensitive Urban Design (ZAM-WSUD) is a water sensitive urban design system that has been designed so that the ongoing maintenance implications for the asset owner are negligible.
The challenge is simple: develop a raingarden design with ‘zero’ additional maintenance requirements compared to a typical kerb and channel streetscape.
The concept consists of:
In addition to the City of Manningham, the partners involved in the design, development and trial of this project include Glen Eira City Council, the CRC for Water Sensitive Cities, Monash University and Melbourne Water.
Prototype design and testing was undertaken in close partnership with Monash University. Some of the design innovations involve:
Testing of the prototypes showed that grass turf was thriving even over the hot summer period, and that the sediment grooves were working well. This process also allowed for slight design improvements which minimise health and safety hazards (tripping potential) and reduce the risk of clogging.
The handbook provides a great overview of the project, with practical details and design plans.
