Compass Business Park is an upcoming mixed-use commercial and industrial development in Seaford which features 6.65 hectares of lots, and will provide leasing opportunities for businesses, such as convenience food, fitness, self-storage and warehousing.
A growth precinct in Melbourne’s southeast corridor, Seaford is just thirty-six kilometres from the Melbourne CBD – and is a gateway to the Mornington Peninsula.
Nearby waterways include Seaford Wetlands, Seaford Beach and Kananook Creek – the area’s wetlands are nature reserve listed and home to a number of rare and endangered migratory species.
Stormwater assets to prevent flooding, and capture pollution are essential to sustainable development in the area. Preventing the conveyance of plastics and litter into receiving waterways plays an integral role in protecting the waterways of Melbourne and Port Phillip Bay.
On-Site Detention & SQIDEP Verified Stormater Treatment
A uniquely challenging multiphase project, Atlan designed solutions for the site’s first phase with initial works incorporating AtlanCube detention tanks with treatment trains across five separate lots.
AtlanCube is our geocellular cubic tank system, and 418,000 litres of total OSD volume across five tank installations will service multiple catchments on the site. The individual tanks measure 34kL, 48kL, 52kL, 140kL, and 144kL – with each tank serviced for pretreatment by treatment trains consisting of multiple StormSack GPTs and FlowFilter tertiary filtration.
Underground installation of these OSD assets will conserve lot yield and enhance project value. The AtlanCube is ideal for mixed-use developments with its capability to accommodate a full range of traffic conditions – from pedestrian foot traffic to class D loads.
The AtlanCube system features a 97% void ratio and 1,000 litres of storage volume per cube. Each cube contains two half-cube components, providing quicker installation timeframes due to its low component count and industry-leading storage volume per module.
Meeting on-site challenges, the AtlanCube reduced lifting and heavy machinery costs compared to heavier tank systems.
StormSack and FlowFilter will meet the site’s water quality requirements. The performance of both devices has been rigorously tested and verified through Stormwater Australia’s SQIDEP framework (Stormwater Quality Improvement Device Evaluation Procotol).
FlowFilter is a tertiary filtration device with verified pollution removal efficiencies of 95% TSS (Total Suspended Solids), 93% TP (Total Phosphorus), 45% TN (Total Nitrogen), 90% Lead (Pb), 53% Zinc (Zn), and 100% Gross Pollutants.
With minimal head drop from inlet to outlet, FlowFilter is a treatment solution that requires minimal excavations and is suitable for low gradient developments. Its innovative internal filter configuration uses up-flow filtration processes and captures a wide range of urban pollutants.
Thirty-one StormSack units will provide primary treatment – and will capture litter, gross pollutants and sediment.
An at-source Gross Pollutant Trap (GPT), the StormSack is deployed in catch basins and installed to capture pollutants near the site surface. Easily maintained, grate access allows cleaning without entry to confined spaces. The StormSack has SQIDEP verified pollution removal efficiencies of 45% Total Suspended Solids (TSS), 47% Total Phosphorus (TP), 25% Total Nitrogen (TN), and 100% Gross Pollutants.
In combination, these water quality devices will stop the conveyance of gross pollutants and sediment to the tank chamber to decrease pollutant build-up from impacting the storage capacity, service life and infiltration capabilities of the AtlanCube tanks.
Atlan Stormwater was honoured to help engineer a complete stormwater solution for this project, ensuring generational assets for pollution capture and flood mitigation are in place to service the local community and protect waterways.
