CCTV Survey in Caerphilly
With a significant share of Caerphilly's housing stock built before 1920, salt-glazed clay drainage and lead-solder copper joints are common across postcodes CF83 to CF86. The combined sewerage system here means foul and surface water share the same pipes, increasing blockage risk during wet weather. CCTV inspection catches these issues early.
CCTV drain surveys in Caerphilly use high-definition colour video to inspect clay and copper sewers for blockages, root ingress, corrosion and joint failure. The WinCan-coded reports are accepted by mortgage lenders and insurers across postcodes CF83 to CF86, and help prioritise repairs before problems escalate.
Drainage in Caerphilly — what local engineers know
Caerphilly falls under Cardiff Council and Welsh Water's water authority area. flood risk is a local consideration, but the combined sewerage infrastructure — foul and surface water in a single pipe — carries a surcharge risk during heavy rainfall. The water supply is soft, which reduces limescale but accelerates corrosion of older copper pipework and lead solder joints. Root ingress, grease blockages and pipe collapse are the most frequent call-outs in Victorian and Edwardian properties, particularly where salt-glazed clay drainage has aged beyond its design life.
- Soft water supply reduces limescale, but slightly acidic pH can accelerate corrosion of copper fittings and lead joints in older Caerphilly properties
- Combined sewerage infrastructure — common in older parts of Caerphilly — means foul and surface water share the same pipe, increasing surcharge risk during heavy rainfall
- Ageing infrastructure in parts of Caerphilly means drain blockages from grease, wipes and root ingress remain the most common call-out reasons
- 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 Caerphilly?
In Caerphilly, 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, Welsh 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 Cardiff.
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 Welsh Water rather than paying for the repair yourself. The combined sewer layout that dominates Caerphilly affects where these boundaries typically fall, and our local engineers know the CF83, CF84, CF85 networks well enough to identify ownership quickly.
