Stormwater Design

Our team delivers customised stormwater design solutions that integrate seamlessly with both natural landscapes and built environments. We design systems that manage runoff volumes, improve flow control and reduce downstream impact. All designs are backed by detailed modelling and engineering expertise, ensuring performance, durability and compliance with local authority standards.

Drainage Inspections & Certifications

We provide drainage inspections and certification services for new and existing developments. We assess system performance, identify compliance issues and issue professional certifications where required. Our inspections help ensure that stormwater infrastructure is constructed to approved specifications and functions effectively long after project completion.

Stormwater Quality Modelling (MUSIC)

Using the Model for Urban Stormwater Improvement Conceptualisation (MUSIC), we assess and optimise stormwater treatment systems for improved water quality outcomes. This modelling helps predict pollutant loads and evaluate treatment performance, ensuring compliance with best-practice environmental guidelines and supporting the design of effective Water Sensitive Urban Design (WSUD) features.

Water Sensitive Urban Design

We incorporate Water Sensitive Urban Design (WSUD) principles into our drainage solutions to improve water quality, reduce runoff and enhance the urban environment. Our approach integrates natural systems such as bio-retention basins, swales and infiltration trenches to manage stormwater sustainably and support ecological health.
