Drain Jetting in Coleraine
Coleraine's hospitality sector—pubs, restaurants, and guesthouses concentrated in BT52—generates high-volume drain waste. Combined with the separate sewer system serving older properties, blockages can cascade across landlord portfolios. Monthly drain maintenance in Coleraine catches misconnections, reduces root growth, and prevents environmental enforcement action from Causeway Coast and Glens Council.
Commercial drain maintenance in Coleraine—for restaurants, HMOs, and B&Bs—runs quarterly or monthly. Services include grease trap servicing, jetting, and CCTV inspections. Northern Ireland Water and Causeway Coast and Glens Council require documented maintenance for licensed HMOs.
Drainage in Coleraine — what local engineers know
Northern Ireland Water classifies Coleraine as a separate sewer area; this means any cross-contamination (e.g., cooking oil into surface drains) is visible and prosecutable. Causeway Coast and Glens Council issued 12 environmental enforcement notices in the past 3 years related to drain misuse. Commercial clients in Coleraine—restaurant owners, B&B managers, landlords with multiple HMOs—benefit from proactive quarterly jetting and CCTV checks. Prevention saves £2,000–8,000 per blockage incident.
- Soft water supply reduces limescale, but slightly acidic pH can accelerate corrosion of copper fittings and lead joints in older Coleraine properties
- Separate sewer system across most of Coleraine: 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 Coleraine means drain blockages from grease, wipes and root ingress remain the most common call-out reasons

Who's responsible for drains in Coleraine?
In Coleraine, 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 Coleraine affects where these boundaries typically fall, and our local engineers know the BT52, BT53, BT54 networks well enough to identify ownership quickly.
