Surf Street Stormwater Upgrade

Knobel Engineers were engaged by City of Gold Coast to undertake the design and documentation of a stormwater upgrade for the Surf Street North Catchment at Mermaid Beach.

A challenging design which consisted of stormwater modelling using XP-SWMM 1D and 2D modelling, to analyse the catchments and pipe sizing. Working with the client, design parameters were altered accordingly to meet specific Gold Coast Water requirements and construction sequences. The design allowed construction works to continue pending the completion of downstream jacking works, allowing the client to achieve budget and time constraints.

The detailed design included pipe jacking up to 1800mm diameter with service relocations and upgrades to water and sewer services, design of special manhole structures and outlet to a tidal canal.
