Sewer Connections Made Easy

Switching from an old septic system to the main sewer can feel overwhelming. There are council approvals to deal with, trenches to dig, and a lot of steps most homeowners don’t know much about. It’s easy to worry about mess, costs, and how long everything could take.

We make the whole process simple. Taking care of everything from decommissioning your old septic to installing your new sewer line and organising the final inspection.

The Yarra Valley is growing fast and we’ve done plenty of these conversions which means you’ll get a team that knows the process inside and out.
