Charleston is a small township on the Onkaparinga Valley road, a handful of streets with farming country spreading out in every direction. It is the sort of place where the house next to the hall is on a council scheme and the one a kilometre up the road is entirely on its own. Adelaide Hills Blocked Drains is a local referral service. We connect Charleston households with licensed local drain plumbers we work with who service the area.
Why Charleston drains block
The township is served by a council community wastewater management scheme, so properties keep their own septic tank and the settled liquid flows on to a shared council line. Three things can block: the drains between house and tank, the tank inlet or outlet, and the council line beyond your connection point. The first two are yours and the third is not, and a camera with a locator settles which is which.
Blocks outside the scheme run full septic systems, where the drains, the tank and the soakage or irrigation area are all the owner's responsibility.
The common faults are the same either way. Older houses still run clay waste pipe with joints that have opened, the trees around them find those joints, and winter in the valley keeps the ground wet enough to slow any soakage area. Stormwater off open paddocks and unsealed tracks silts up pits and the flatter runs of pipe.
What clearing a blocked drain involves
The licensed drain plumbers we work with usually start with a CCTV drain camera to establish where the fault sits, then clear the line with jet blasting. Tree roots in drains are cut back with a root nozzle, and a broken section is repaired with relining where the pipe suits it.
Pumping out a tank is a licensed liquid waste contractor's job, and the plumber will tell you if that is what the situation needs.
A standard clear typically costs $150 to $400. Root clearing typically runs $250 to $600. A camera inspection runs $249 to $600, or $350 to $900 combined with jetting. If roots have broken an old pipe, relining typically costs $3,000 to $8,000 or more.
Frequently asked questions
How do I find out if I am on the council scheme?
Your council can confirm it from the property records, and a plumber can usually tell on site from the tank and connection arrangement.
Who is liable if the council line backs up into my tank?
If the fault is in the shared line past your connection, it is the council's to fix. Evidence from a camera and locator is what makes that conversation straightforward.
Can I connect stormwater to the scheme line?
No. Stormwater and wastewater are separate systems, and sending roof water into a tank or scheme line overloads it quickly.
