Frequently Asked Questions
Which Brisbane codes do you design stormwater to?
We design to the Queensland Urban Drainage Manual (QUDM) and the Brisbane City Council Subdivision and Development Code, plus the relevant City Plan overlays, so your stormwater design is council-ready for Brisbane City Council assessment.
Do I need on-site detention for my Brisbane development?
Most Brisbane developments that increase impervious area require on-site detention to keep post-development runoff at pre-development rates. We design tank or basin storage to Brisbane City Council's OSD requirements and certify it for compliance.
