Drainage Services Bow
Blocked drain clearance, CCTV surveys and no-dig relining for Bow homes, from engineers who know Bow buildings.
Local knowledge
Bow housing, from a drainage engineer's side
Bow features extensive Victorian and Edwardian terraced streets interspersed with larger ex-industrial sites converted to residential use and modern housing estates. The area has a high proportion of shared drainage runs serving long terraces, with complex responsibility boundaries. Former industrial land can present ground contamination issues affecting pipe bedding. Modern estates often utilise below-ground attenuation tanks and sustainable drainage systems (SuDS) integrated with older sewer networks.

What fails here
Common drainage problems in Bow
01
Terraced House Shared Drain Responsibility Disputes
Long runs of shared drains serving entire terraces lead to frequent disputes over maintenance responsibility between landlords and freeholders. Our engineers provide definitive CCTV evidence tracing the drain line and identifying the precise location of defects, forming the basis for legally sound reports.
02
Industrial Ground Subsidence
Historical industrial use has led to variable ground conditions, causing differential settlement and fracture of drainage pipes, particularly at pipe joints. CCTV survey documentation classifies settlement defects (SD) and provides visual evidence of ground washout for structural insurance reports.
03
SuDS & Attenation Tank Blockages
Modern estate sustainable drainage systems, including permeable paving feeds and attenuation tanks, are prone to silt and sediment accumulation, reducing capacity. Regular CCTV inspection with flow monitoring provides documented performance data for management companies.
04
Aged Cast Iron Downpipe Corrosion
Original cast iron rainwater downpipes integrated with combined drainage on Victorian properties suffer from internal corrosion and scaling, restricting flow. Internal CCTV inspection documents the extent of corrosion (CR) for pre-purchase surveys or planned maintenance programmes.
Three methods, one visit
High-pressure jetting
Blasts grease, silt and root growth from pipe walls without digging.
CCTV survey
A camera on rods or a crawler unit records the pipe condition end to end.
No-dig relining
A resin liner is cured inside the damaged pipe instead of excavating it.
