Local knowledge
Harlesden housing, from a drainage engineer's side
Harlesden's housing mix includes tightly packed late-Victorian/Edwardian terraces alongside some inter-war residential blocks. The area experiences significant surface water challenges that can impact combined sewers. Many drainage systems are at or beyond their functional lifespan, with evidence of widespread patch repairs. The property turnover rate can mean drainage maintenance has been deferred, leading to acute failure.

What fails here
Common drainage problems in Harlesden
01
Surface Water Ingress into Combined Sewers
Defective gullies and cracked pipework allow excessive surface water to enter the combined foul system, especially during heavy rain. This leads to surcharging and internal flooding. CCTV surveys with dye testing are used to document the precise points of ingress for insurance and repair purposes.
02
Multiple Patch Repair Failures
A history of localised, short-term repairs has left sections of pipework with multiple incompatible linings, cement patches, and internal protrusions. These create turbulence and snag points for debris. A detailed CCTV report cataloguing each historical defect is vital for planning a comprehensive rehabilitation strategy.
03
Acute Collapse Following Deferred Maintenance
Long-neglected drains in rental properties often present with sudden, complete collapse. Emergency diagnosis via CCTV is required to determine the extent and specify the repair method (e.g., excavation vs. liner), with the footage serving as immediate evidence for landlords and insurers.
04
Debris Accumulation from High-Turnover Tenancies
Rapid tenant turnover in rental properties leads to inappropriate items being flushed, causing severe downstream blockages. These often comprise a complex matrix of waste requiring careful extraction. Documenting the retrieved items can support landlord actions against previous tenants.
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.
