CCTV Survey in Londonderry
Londonderry's Victorian and Edwardian housing stock sits over clay and rubble-filled drains vulnerable to subsidence, root ingress, and structural failure. Northern Ireland Water's soft water supply reduces limescale but allows acidic conditions that corrode lead and copper joints in 100+ year old properties. CCTV surveys reveal hidden defects before purchase or mortgage valuations, particularly critical across the BT47–BT50 postcodes where Georgian terraces and rural properties share aging infrastructure.
CCTV drain surveys in Londonderry detect root ingress, structural cracks, and misconnections in Victorian properties served by Northern Ireland Water. Soft acidic water corrodes lead joints; surveys are standard pre-purchase inspections across BT47–BT50 under Causeway Coast and Glens oversight.
Drainage in Londonderry — what local engineers know
Causeway Coast and Glens Council oversees Londonderry's separate sewer system, where misconnections (surface drains plumbed with foul drainage) trigger environmental enforcement action. Northern Ireland Water serves 10,000 residents with soft water that accelerates corrosion of lead joints and copper fittings in properties built before 1980. CCTV surveys are increasingly standard in pre-purchase surveys across Londonderry, as mortgage lenders require defect reports on Victorian stock. The acidic water chemistry makes drain coating failures visible on camera within 5–8 years of installation.
- Soft water supply reduces limescale, but slightly acidic pH can accelerate corrosion of copper fittings and lead joints in older Londonderry properties
- Separate sewer system across most of Londonderry: misconnections (e.g. washing machines plumbed into surface water drains) are a known local issue and can result in environmental enforcement action
- Ageing infrastructure in parts of Londonderry means drain blockages from grease, wipes and root ingress remain the most common call-out reasons

Who's responsible for drains in Londonderry?
In Londonderry, 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, Northern Ireland 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 Causeway Coast and Glens.
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 Northern Ireland Water rather than paying for the repair yourself. The separate sewer layout that dominates Londonderry affects where these boundaries typically fall, and our local engineers know the BT47, BT48, BT49 networks well enough to identify ownership quickly.
