Northern Beaches Council – Detailed Design of 7 GPTs

In 2018 Optimal Stormwater won the tender to design three GPTs in Manly, which Northern Beaches Council expanded to seven devices in total including reconstruction of the Manly Beach stormwater outfall at North Steyne. The Scope of Work involved investigation into a range of different GPTs to select the most appropriate devices, catchment analysis, modelling (DRAINS and MUSIC), underground service scanning, consultation with authorities, geotechnical investigation, detailed design, preparation of construction specifications, cost/benefit analysis and prioritisation.
