• Different ways to
design infrastructure
• Great engineering
design &
construction
• Failure in
performance
• Maintenance

SLIDE 4• Maintenance in early stages
• Communication with asset owners and stakeholders
• Understanding of the limitations and capacities
• Understanding of the design preferences
• Preparation of the maintenance plan
• Simplifying the proposed infrastructure where possible

SLIDE 7• Design and Construction Stages
• Simpson Street Tunnel lining & protection
• Construction of box culvert under the
race track
• Construction of retarding basin &
associated infrastructure to cater for
existing catchment plus 24ha diverted
catchment
• Extension of retarding basin to cater for
additional 61ha

SLIDE 8• Design Considerations
• Diversion of runoff towards the retarding basin via pit and pipe
• Diversion of low-flow towards the sediment basin
• Diversion of 10% AEP flow to the retarding basin
• Management of 1% AEP overland flow-path
• Consideration of an emergency backup to avoid overflow on the
race track
• Maintenance of Park Street drainage

Designed infrastructure
• pipes & pits system
• The flowrate up to 10%AEP will be
diverted towards the retarding basin
• The flowrate higher than 10% AEP
will be directed to the Tozer Road
channel
• Sediment basin will cater for the flow
up to 3mnts (95% AEP)
• Higher flow, up to 10% AEP will be
directed to the Retarding Basin
• The existing outlet will cater for the
flow discharging from Park Street
drainage system and the Retarding
Basin

Special Design Considerations for Maintenance
![Page 12: Simpson Street Stormwater Management System](https://reader031.vdocuments.us/reader031/viewer/2022012301/61e1902e72ce9639d95d42df/html5/thumbnails/12.jpg)
SLIDE 12• Maintenance considerations
• Automatic diversion with minimum manual involvement
• Self cleaning factors
• Simplicity
• Safety
• Cost effectiveness

SLIDE 14• Conclusion
• The goal of designing an infrastructure is to be able to use it when is required.
• Evolution of design vs construction/maintenance cost.
• Auto diversion of runoff reduces the risk of wash out during a major event.
• Communication with the relevant stakeholder and infrastructure owner.
• Considering the constructability & maintainability of the proposed infrastructure.
• Analysis of design safety.
