Sewerage Treatment Plant Installations
Septic and Wastewater Solutions for Properties Without Mains Sewer Connections
If you’re building or living on a property without mains sewer, a properly installed and maintained sewerage treatment system isn’t just a good idea — it’s a must. Whether you’re on a rural block, bushland property or coastal site, we can help you get set up with the right wastewater solution from the start.
At All Done Plumbing & Drainage, we specialise in sewerage treatment plant (STP) installations across Bass Coast, South Gippsland and King Island. We handle the full process from design and approvals through to excavation, installation and long-term servicing.
We install sewerage systems for:
New builds on blocks with no sewer connection
Off-grid homes and holiday houses
Replacement of old or failed septic systems
Upgrades to more efficient treatment setups
Compliance with council and environmental health requirements
We work with both traditional septic tanks and modern advanced treatment systems, depending on your site, usage and local regulations.
What’s involved in installing a treatment plant?
Site assessment and consultation
System selection based on property size, soil type and usage
Council liaison and permit applications
Excavation and base preparation
Installation and connection of tanks and dispersal systems
Final testing, commissioning and compliance certification
We’re familiar with all the major treatment systems on the market and can advise you on what will work best long-term — including systems with irrigation dispersal, energy-saving units, and those suited to tricky or compact blocks.
Why local knowledge matters
Not every property is the same — and out here, we see it all. Sandy soils, clay-heavy sites, high water tables, steep driveways, or limited access for machines. We’ve installed systems in all kinds of conditions and will find the safest, most effective option for your block.
We also know what local councils are looking for when it comes to septic and treatment plant approvals. We’ll guide you through the paperwork and ensure the install is compliant and built to code.
