Aquacomb Solutions Case Study

Aquacomb installed large-scale OSD systems for this EDA Construction project based in Maroubra, in Sydney’s East. Installation was completed in October 2016.


Aquacomb OSD was the perfect simplified solution to a complex and time consuming large-scale onsite water retention issue. The builders were unable to utilise deep excavation for this project, encompassing four, two-storey villa developments. Aquacomb took on this project making resourceful use of minimal foundational space to integrate this unique water storage solution.

The solution

The high water table level at this beachside site caused considerable problems with satisfying the council OSD requirements for stormwater retention on-site. This prevented deep excavation as a solution and Aquacomb as chosen as a simple and highly efficient resolution to this problem. Our OSD system, developed alongside EDA construction builders,¬†illuminated the alternative solution to excavating a massive pit, to meet council’s OSD requirements.

The Aquacomb on-site stormwater detention (OSD) system allowed for a large volume of water detention without compromising space or requiring deep excavation. The specified system included 100 inter-connected pods linked laterally to retain 35,000 litres of rainwater overflow to meet on-site detention (OSD) needs. The system was incorporated in the concrete floor of the underground car park, stored stored out of sight.

Why Aquacomb

Aquacomb provided a simple and easily installed OSD solution which was highly cost and time effective.

From complex to straight forward OSD requirements Aquacomb is the answer
