Local knowledge
Coulsdon housing, from a drainage engineer's side
Coulsdon has a mix of 1930s semi-detached homes and larger detached properties, often set on sloping plots. The gradient means drainage runs can be long and deep, following the fall of the land. Many properties have older septic tanks or cesspits that were later connected to the mains sewer, leaving redundant sections of pipe in the ground. The area is also bordered by green spaces with mature tree cover.

What fails here
Common drainage problems in Coulsdon
01
Deep Drain Collapse on Slopes
Drainage runs on sloping plots can be laid very deep to maintain correct fall. Pressure from the overburden of soil and shifting ground on hillsides can cause these deep, older clay pipes to collapse, requiring significant excavation to reach and repair.
02
Abandoned Cesspit Hazards
Many older properties were originally served by septic tanks or cesspits. When connected to the mains, these were often simply bypassed and left in the ground. Over time, they can collapse or fill with silt, causing unexplained subsidence or drainage flow issues.
03
Boundary Tree Root Damage
Properties bordering the green belts and old woodland around Coulsdon are susceptible to root intrusion from large, established trees. Roots can travel long distances to seek out moisture from drainage runs, causing extensive and repeated blockages.
04
Incorrect Fall from DIY Work
Homeowner modifications to drainage on sloping gardens, such as for new outbuildings or soakaways, sometimes install pipes with insufficient fall. This leads to constant standing water and silt build-up in the new section, which then washes back to cause main drain blockages.
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.
