Blocked Drains
The everyday call: a laundry tub that will not empty, a shower filling around your ankles, a toilet slow to drop. We clear the line, then find what blocked it.
Drainage Northgate

When to Call a Drainage Plumber in Northgate
Four lanes cover nearly every drainage call, and each lane starts from a different symptom:
Water backing up inside
points to a blocked sewer, and the blocked sewer page explains what that means and how it gets cleared.
A sink, shower or floor drain running slow
is the everyday blocked drain, detailed on the blocked drains page.
Pits and gullies brimming after rain
belong on the blocked stormwater page, which is where most calls from the flats land.
A drain that keeps blocking for no clear reason
is the cue for a CCTV drain inspection, because guessing gets expensive.
Not sure which lane you are in? Ring (07) 3067 4276 and describe the symptoms; we will point you to the right page.
Rigid Drains in Northgate's Old Streets
Most of the housing here went up between the 1910s and the 1970s, long before plastic pipe, and that single fact shapes most of the drainage work we do.
Rigid pipe, open joints
House drains from those decades went in as rigid pipe, not plastic, and their joints have had generations to shift. Small offsets catch tissue and silt, which is what usually slows a drain in this suburb.
A mid-century public network
The public sewer system here is mostly unreinforced concrete and asbestos-cement main, which points to a mid-century build that private drains of mixed rigid materials join onto.
Soft ground doing its slow work
Low ground in the east carries peat and soft mud, and that ground compresses under decades of fill and passing traffic until a buried pipe drops out of its grade.
None of that is a mystery to us. It is the standard story of a mature junction suburb, and we quote with it in mind rather than treating every line like a new estate's.
The Four Drainage Services
Each page below carries the full picture: what the job is, what drives it on these streets, and how we handle it.
Blocked Sewer
Sewage surfacing in a yard or bathroom is a health matter before it is a plumbing one. This page covers the warning signs, the gullies to keep clear of, and clearing the line.
Blocked Stormwater
Summer storms give stormwater real work here. This page covers pits, gullies and downpipes, and why a sluggish stormwater line matters more on the mapped low streets than anywhere else nearby.
CCTV Drain Inspections
When a drain keeps blocking, a camera run down the line ends the guesswork. This page covers what the inspection shows, when it earns its keep, and how the recording shapes the fix.

How a Drain Gets Diagnosed in Northgate
Diagnosis in this suburb follows the water, because the ground tells most of the story before any camera goes down.
Start with the pattern
A single slow fixture suggests a local blockage; every drain in the house dragging at once suggests the main line; gullies that fill only when it rains suggest stormwater. The pattern usually narrows the fault to one stretch of pipe before we open anything.
Then let the soil explain it
The alluvial flats and fill under the low ground behave differently from the shale sections, so the same symptoms can have different causes a few streets apart. A dropped pipe in the soft ground and a root-struck joint elsewhere need different fixes.
Then confirm with the camera
Where the history is unclear or the blockage keeps returning, a CCTV inspection shows the inside of the line: the shifted joint, the root intrusion, the sagging section. The recording means we repair the piece that actually failed instead of re-clearing the same trap every season.
Stormwater gets its own reading
Council's flood awareness mapping flags creek and storm tide risk over a large share of the suburb, east and centre, and once a storm hits, every pit and gully fills at once. A house drain that is only partly clear has nowhere to empty while they are brimming.
That is why stormwater calls on the mapped streets get priority treatment, even when the sun is back out by the time we arrive. Anything overflowing inside the house, though, moves straight to the emergency plumbing page.
Groundwater on Northgate's Eastern Flats
The second local factor is water that arrives from below rather than from the sky.
A shallow water table
The eastern flats rest on coastal-plain mud, peat and swamp deposits, and the water table there sits close to the surface. A trench opened near the low end of Nudgee Road or Toombul Road can fill on its own.
Silt with a way in
Cracked joints near the water table let silt into the line, and it settles in the flat runs, so the same house drain slows again no matter how often it is cleared.
Rainfall with a job to do
The climate record puts the yearly average near 1,039 millimetres, and most of it lands in the muggy summer storm season, on ground that is already wet.
For you, that means two things. First, a recurring blockage here often has a structural cause worth finding, not just a symptom worth clearing. Second, any excavation on the flats needs proper support and dewatering allowances, which we build into the fixed quote before a shovel goes in.

Northgate Drainage Questions
Call (07) 3067 4276Who owns the sewer pipes around my Northgate home?
Urban Utilities looks after the council sewer pipes beneath the roadway, but everything beyond that point is the owner's to fix, so any repair inside your boundary is your job to organise.
Why do drains keep blocking in the older streets near Northgate station?
Drains from that era are rigid lengths rather than plastic, and the joints have shifted over decades, so small offsets trap silt and tissue and one line can slow down again and again.
Does the high water table under Northgate cause drain problems?
That happens east of the line, where the water table sits high, letting silt creep through any cracked joint and settle along flat sections, and drains there rarely stay free for long.
What does a CCTV drain inspection involve?
A camera travels the pipe and records what it passes, revealing shifted joints, root growth, dropped sections and the exact position of a fault, so the repair lands on the real problem.
Can stormwater pits in Northgate overflow in heavy rain?
They can, because Council's flood awareness layers spread across the suburb's low eastern ground, and when a storm brims every pit and gully together, a partly clear house drain has nowhere to empty.
