Septic tank installation in the Adelaide Hills
Out past the sewer line, your septic system does a job you never want to think about. We supply and install new septic tanks, aerobic and Envirocycle systems and soakage trenches across the Adelaide Hills, Strathalbyn and the Murraylands, and upgrade old systems that have had their day. We're a local family plumbing business out of Mount Barker, rated 4.9 from 93 Google reviews.
New builds
New septic systems for new builds and rural blocks
Building on a block with no sewer connection means picking the right system for the site before anything else. Soil type, slope, how close you are to a creek or bore and how many bedrooms the house has all decide what will work and how big it needs to be. We'll look at the block with you, explain the options in plain English and install the system, the tank and the disposal side, so you're dealing with one plumber from the ground up.
Aerobic systems
Aerobic and Envirocycle systems
Aerobic systems treat wastewater to a higher standard than a conventional tank, so the water can be used to irrigate your garden rather than going into the ground through a trench. They suit smaller blocks, poor-draining soil and sites where a trench just won't fit. We supply and install Envirocycle and other aerobic systems, and set up the irrigation side so it works on your block.
Disposal
Soakage trenches
A septic tank is only half the system. The trench is where treated water soaks back into the ground, and on Hills clay a trench that's too small or in the wrong spot will waterlog, smell and eventually back up into the tank. We dig and lay new trenches sized for the soil and the household, and replace trenches that have failed.
Upgrades
Upgrading an old septic system
Plenty of older Hills and Strath properties are still running the tank that went in when the house was built. If yours is cracked, undersized for the family you've got now, or the trench keeps flooding, we can replace it with a new conventional or aerobic system. If you're renovating or adding bedrooms, it's worth checking the system can handle the extra load before the work starts.
Approvals
Council approval
In South Australia, a new septic system or an upgrade needs approval from your local council before it goes in. Getting the system type and size right from the start makes that process a lot smoother, so we'll talk it through with you before any digging starts.

Frequently asked questions
Do you do septic pump-outs?
No, we focus on supplying and installing new septic and aerobic systems, trenches and upgrades. For a pump-out you'll want a liquid waste contractor.
Should I get an aerobic system or a conventional septic tank?
It depends on your block. Conventional tanks with a soakage trench suit larger blocks with soil that drains well. Aerobic systems like Envirocycle suit smaller or steeper blocks, heavy clay, or anywhere you'd rather reuse the water on the garden. We'll tell you what fits your site.
How do I know if my septic system needs upgrading?
Common signs are slow drains through the house, smells around the tank or trench, soggy ground or lush green patches over the trench, and water backing up after heavy use. An older tank that's struggling with a bigger household is also worth looking at.
Do you install septic systems for new builds?
Yes. New builds on unsewered blocks are a big part of our septic work. We install the tank or aerobic unit, the plumbing to it and the trench or irrigation, so it's all one job.

Had a new hot water system installed and also shower renovation done. Ashley had great ideas and understood what I was asking. Super happy with the work. Highly recommend
AHighly recommend Ash and the team at Assigned Plumbing for a great service, excellent response and high level of quality works completed at our place in Birdwood. The team responded to our stormwater leaks in a very timely manner, finished the job rapidly, tested and verified before providing sound advice on some future improvements. Will call on again in the future for all my plumbing maintenance and projects. Thanks team!
MAfter seeing my latest water bill had tripled I discovered I had an underground leak at the metre , luckily assigned plumbing was able to come the same day I rang them, fixed the leak and had the water back on for the weekend
SAshley and his team (Max and Darcy) are excellent – prompt, efficient, polite and respectful. Great service at a very reasonable cost. Highly recommended.
EGreat service and professional advice to help with positioning and install of wood heater at home. Thankyou Ash!
JHad Ash do two new/renovated bathrooms for us! From quote to completion, couldn’t say a bad word! Everything went exactly as he said on the day he said it would. He was very clean and respectable during the process and the workmanship was perfect. Couldn’t be happier!!
BI had a shitty job no one else wanted to touch and got hold of this great mob of plumbers and in no time they were where I needed them and they completed the job very professionally and in a timeframe that I didn’t think possible. Amazing people, great work ethics and the price was fair and reasonable. I highly recommend them for any plumbing services that you require and I will use them again if the situation arises that needs good work done correctly and within a decent time frame. Thanks Assigned Plumbing Services. 😁
TAshley and team were fantastic. Came on time, provided really good advice and got the job done and went the extra mile with additional materials (did not charge) to get the job done properly. Thanks Ashley and Maxi, appreciate your work and would highly recommend them.
JGreat plumber. Great communication, great job and great value!
