You do not need a local office to get a Brisbane stormwater design approved. You need an engineer who knows Brisbane City Council’s standards. RI ENG PTY LTD prepares stormwater plans and reports for Brisbane residential projects, delivered by email and built to BCC requirements.

Stormwater Engineering for Brisbane Residential Projects

Brisbane has its own stormwater management framework. Brisbane City Council (BCC) applies Queensland plumbing legislation and its own Stormwater Management Design Objectives.

New houses, duplexes and townhouses in Brisbane must demonstrate that stormwater from the developed site does not damage neighbours or the public drainage network.

This means a drainage engineer must calculate flows, design the pipe and pit layout, and often design an on-site detention or retention system.

RI ENG PTY LTD provides stormwater engineering for Brisbane residential projects on a remote basis. You do not need a local engineer with a local office — you need a competent one with the right knowledge.

We know Brisbane City Council’s standards and design to them.

What Brisbane Councils Require for Drainage Approval

Brisbane City Council requires a stormwater management plan as part of the development application for most residential projects.

The plan must show pre-development and post-development flows, peak flow attenuation where required, and the drainage path to an approved discharge point.

BCC also has requirements around water quality. Some developments need to demonstrate retention of the first-flush pollutant load through a rainwater tank or bioretention device.

We prepare plans and reports that address all BCC requirements in one package — no revision requests, no back-and-forth.

For townhouse and duplex projects in Brisbane, we include shared drainage easement advice and future subdivision considerations.

Remote Service — How It Works

Working with us from Brisbane is simple. You send your site plan, survey, architectural plans and any DA conditions.

We review them, confirm scope and fees within 24 hours, and begin the design.

You receive a drainage plan and report by email within 3–5 business days.

If your certifier or BCC has questions, we respond directly.

We have delivered stormwater designs for residential projects in Brisbane, the Sunshine Coast, Gold Coast and regional Queensland.
