Blocked Drains in Selkirk
Selkirk's combined sewer system is a blockage hotspot. Victorian and Edwardian properties (TD7–TD9) share foul and surface water pipes, so tree roots and silt accumulate unchecked by limescale. Soft water from Scottish Water means blockages form from pure debris, not mineral deposits. We clear and diagnose the underlying cause.
Selkirk's combined sewer system merges foul and surface water, creating blockage hotspots at tree-root ingress and silt traps. Soft water from Scottish Water means mineral deposits don't seal cracks, accelerating root penetration. CCTV diagnosis identifies blockage type and guides targeted clearing.
Drainage in Selkirk — what local engineers know
Scottish Borders Council manages Selkirk's drainage infrastructure. The combined sewer system (TD7, TD8, parts of TD9) dates to Victorian times and uses clay or cast-iron pipes vulnerable to root ingress and joint failure. Scottish Water's soft supply doesn't naturally seal minor cracks through mineral deposition; this benefits water quality but means drain joint failures don't self-heal. Autumn rainfall causes surcharge in combined systems, backing up foul water into properties and exacerbating blockages.
- Soft water supply reduces limescale, but slightly acidic pH can accelerate corrosion of copper fittings and lead joints in older Selkirk properties
- Combined sewerage infrastructure — common in older parts of Selkirk — means foul and surface water share the same pipe, increasing surcharge risk during heavy rainfall
- Moderate flood risk in parts of Selkirk — drainage systems near low-lying areas can surcharge after prolonged rain, and sump pump maintenance is advisable
- With 28% 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 Selkirk?
In Selkirk, 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 Scottish Borders.
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 Selkirk affects where these boundaries typically fall, and our local engineers know the TD7, TD8, TD9 networks well enough to identify ownership quickly.
Blocked Drains prices in Selkirk
Every Selkirk job is quoted as a fixed price before work starts — what we quote is what you pay, with no call-out fee for providing the quote. The final price depends on access (an external inspection chamber is quicker than internal-only access), the pipe material and condition , and how established the blockage or fault is. Request your free quote and we'll confirm the price and your engineer's ETA in the callback.
