BPM Projects was engaged by a Top-Tier Client to undertake a Stormwater Separation Study at their major Terminal following a 1-in-100-year rainfall event that resulted in stormwater entering the existing oily water system. Delivered over eight weeks, the study assessed system vulnerabilities and identified preventative and protective measures to mitigate floodwater impacts and protect the oily water separator.

Following the study, BPM Projects progressed the recommended solutions through Concept Study, FEED and Detailed Design, including the design of protective levee walls and upstream pump stations to capture and manage excess stormwater. BPM also provided construction support, ensuring continuity, quality assurance and the successful execution of the project.

BPM Projects delivered a Stormwater Study supported by a 3D QGIS model and detailed survey data to assess flood levels at the oily water separators under various rainfall scenarios, calibrated against evidence from a 1-in-100-year event. The model identified contributing catchments and stormwater volumes, enabling the development of effective upstream capture and protection measures. BPM Projects directly managed specialist survey subcontractors to safely deliver high-quality topographical and underground survey data within the project timeframe.
