Drain Jetting in Caerphilly
Caerphilly's older housing stock — with a significant share of properties built before 1920 — relies on salt-glazed clay drains and lead-soldered copper pipework that need regular attention. The combined sewerage systems common across CF83, CF84 and CF85 mean foul and surface water share the same pipe, increasing blockage risk during wet weather. Planned maintenance stops these problems before they become emergencies.
Drain maintenance in Caerphilly involves scheduled jetting, root cutting and CCTV inspections for properties on combined sewers. Regular checks prevent blockages in older salt-glazed clay pipes, especially critical in CF83-CF86 where Victorian properties predominate.
Drainage in Caerphilly — what local engineers know
Welsh Water supplies soft water to Caerphilly, which reduces limescale but the slightly acidic pH accelerates corrosion in older copper and lead joints — a recurring issue under Cardiff Council's jurisdiction. The combined sewer infrastructure means grease, wipes and root ingress cause the most frequent blockages in neighbourhoods with older drainage. Root ingress in salt-glazed clay pipes is particularly common in CF84 and CF85, where Victorian terraces were built over decades-old street trees. Regular jetting and CCTV inspection catch joint failure and pipe collapse before they force emergency digs.
- 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.
