Sewer Connections in Brisbane
Gravity and pressurised sewer connection design, rising mains and pump stations, coordinated with Urban Utilities and Unitywater.
Compliant sewer and wastewater connection design across Brisbane and South-East Queensland. We design gravity-fed and pressurised (pump) sewer systems, rising mains and pump stations, carry out site and capacity assessment, and manage the authority standards and approvals with Urban Utilities and Unitywater — so your connection is designed right and approved without the back-and-forth.

Frequently Asked Questions
Do I need an engineer or can my plumber handle the sewer connection?
For a single house connecting to an existing sewer in a serviced area, your plumber usually applies directly to the network operator. For subdivisions, infill developments, anything needing a sewer main extension, or sites where the existing sewer can't service the proposal — the operator requires engineered design, and that's where CWD comes in.
What if there's no sewer main at my property?
We investigate the nearest connection point and design the extension or property connection branch required to reach it, including grades, depths and any easements. Where a gravity connection isn't feasible, we assess pump-station or pressure-sewer options and coordinate the design with the operator.
When do I need a sewer pump station or pressure sewer?
When a gravity connection to the existing main isn't feasible — typically where the main sits higher than the site or too far away — we assess pump-station or pressure-sewer options, size the system and rising main, and design it to the network operator's standards and approval requirements.
