Scarborough sits at the top of the peninsula, with the marina and boat harbour on one side and streets climbing to the headland above. The old holiday stock is steadily being replaced: fibro beach shacks come down and two-storey rebuilds and small unit blocks go up, often on the same sewer connection that served the original house. Moreton Bay Blocked Drains is a local referral service that connects Scarborough residents with QBCC-licensed local drain plumbers we work with.
Why Scarborough drains block
The rebuild pattern causes more drain problems here than anywhere else on the peninsula. A new house with three bathrooms is connected to a line that was laid for a two bedroom cottage, and the pipe is often decades old clay that nobody inspected before the slab went down. The extra load finds every weak joint.
Slope is the second factor. Water runs fast off the elevated streets and carries soil, mulch and leaf litter straight into stormwater pits. Below the headland, that material drops out where the ground flattens and the line silts.
Salt and age handle the rest. Grates, covers and older metal fittings corrode faster near the harbour, and the mature trees in the established streets behind the foreshore are well into the clay pipe below them.
What clearing a blocked drain involves
The licensed drain plumbers we work with start with a CCTV drain camera when a line is old or the history is unknown, then clear with jet blasting or an eel depending on what the camera shows. Root damage in an old line is often best fixed with pipe relining rather than digging up a new driveway.
A standard clear typically costs $150 to $400. A camera inspection runs $249 to $600, or $350 to $900 combined with jetting. Root clearing typically costs $250 to $600. Relining typically costs $3,000 to $8,000 or more. You get a price before any work starts.
Frequently asked questions
We are rebuilding. Should the old sewer line be checked?
Yes, and before the slab goes down if possible. A camera inspection while the block is clear is cheap. Finding a failed line under a finished house is not.
Why does the stormwater pit fill with soil?
Runoff from the slope above carries soil and mulch into the pit, and it settles where the ground flattens. Jetting clears it, and a silt trap slows the build-up.
Our small unit block has one shared line. Who is responsible?
Shared drainage on common property is usually the body corporate's responsibility, while a blockage inside one lot's own fixtures normally falls to that owner. A camera report settles the question.
