Commercial Drainage & PPM
Across Sunderland
WJA-certified independent specialists providing 24/7 emergency response, high-pressure jetting, and interceptor maintenance.

A reactive approach to drainage often results in emergency costs and lost revenue. Our bespoke PPM contracts are designed to keep your systems flowing through regular, scheduled inspections and cleans. During these visits, our engineers perform deep descaling, silt removal, and structural integrity checks using WRc-standard CCTV technology. By identifying and addressing scale build-up or minor fractures before they result in a blockage, we help protect your high-value stock, flooring, and floor-level machinery from potential wastewater flooding.

Food service and industrial premises require specialist care to remain compliant with environmental regulations. We provide professional grease trap servicing for commercial kitchens to prevent the accumulation of FOG that leads to severe internal blockages. For industrial sites, our team manages the cleaning and maintenance of petrol and oil interceptors, ensuring your site remains compliant with environmental standards. We utilise heavy-duty, high-pressure water jetting units capable of clearing industrial-grade obstructions, restoring your pipework to its full bore capacity without the need for destructive intervention.

Our team is highly familiar with the specific drainage challenges present across Wearside. We understand the historical impact of regional mining activity, which can cause ground movement and shear fractures in clay pipework under warehouse slabs. Furthermore, our experience with the infrastructure in newer industrial zones, such as the estates around Washington, allows us to diagnose issues within modern PVC systems efficiently. We work with an acute awareness of the boundary between private commercial drainage and the statutory Northumbrian Water lateral network, ensuring you only pay for work within your site remit.

APJ Drainage operates with the safety and reliability that commercial contracts demand. We hold the necessary Water Jetting Association (WJA) certifications and Confined Space training to work safely in complex environments. All our operations are backed by £1,000,000 in Public Liability Insurance, and we provide formal Risk Assessments and Method Statements (RAMS) for every site visit. As a registered entity (Company No. 16335586), we are committed to providing transparent, WRc-compliant reports that satisfy the requirements of insurance providers and commercial auditors.
