Blocked Drains in Greenock
Greenock's combined sewerage system merges foul and surface water in shared pipes — a design from the 1880s that still dominates PA16 and PA17. Heavy Atlantic rainfall surcharges these pipes, pushing sewage back into Victorian terraces and modern homes alike. Cast-iron soil pipes in 1920s tenements collapse from corrosion; plastic drains in post-1980 estates crack under tree-root pressure or wet-ground movement.
Blocked drain clearing in Greenock tackles combined-sewerage surcharge (foul and surface water backing up during Atlantic rainfall), corroded Victorian brick drains shedding internal debris, and tree-root-invaded plastic pipes in waterlogged modern estates. CCTV surveys identify damage; rodding or high-pressure jetting restore flow across PA15–PA18.
Drainage in Greenock — what local engineers know
Inverclyde Council's combined sewerage in Greenock means one blocked pipe affects multiple properties. Victorian and Edwardian terraces in PA15 and PA16 have brick-and-mortar drains that crumble from acidic Greenock water and 140 years of use. Heavy Atlantic rainfall — typical for Greenock's exposed coastline — regularly surcharges combined pipes, backing sewage into basements and gardens. Modern residential estates in PA17 and PA18 often suffer blocked mains from tree roots invading plastic pipework in waterlogged ground. Scottish Water manages the public sewers; Inverclyde Council enforces local building standards for private drains.
- Soft water supply reduces limescale, but slightly acidic pH can accelerate corrosion of copper fittings and lead joints in older Greenock properties
- Combined sewerage infrastructure — common in older parts of Greenock — means foul and surface water share the same pipe, increasing surcharge risk during heavy rainfall
- Moderate flood risk in parts of Greenock — drainage systems near low-lying areas can surcharge after prolonged rain, and sump pump maintenance is advisable
- With a significant share of properties built before 1920, salt-glazed clay drainage and lead-solder copper pipework are common — pipe collapse, root ingress and joint failure are recurring call-out drivers.

Who's responsible for drains in Greenock?
In Greenock, responsibility for a blocked or damaged drain depends on where the fault sits. As a homeowner you are responsible for the drains within your property boundary that serve only your home. Since the 2011 private sewer transfer, Scottish Water is responsible for shared sewers and lateral drains beyond your boundary — even where they run under private land. Road gullies and highway drainage are maintained by Inverclyde.
This matters because it determines who pays. If our engineer's CCTV inspection shows the fault is in a shared sewer, we'll tell you — and you can report it to Scottish Water rather than paying for the repair yourself. The combined sewer layout that dominates Greenock affects where these boundaries typically fall, and our local engineers know the PA15, PA16, PA17 networks well enough to identify ownership quickly.
