Victorian clay drainage in Deptford, New Cross, and Lewisham town. Edwardian clay throughout much of the residential stock. 1930s vitrified clay in Catford and Sydenham suburbs.
London Clay across most of the borough, with river terrace alluvium along the Ravensbourne valley. The Ravensbourne floodplain creates elevated groundwater risk in low-lying areas.
Common drainage issues include: Ravensbourne river flooding risk affecting drainage capacity in low-lying areas; Root infiltration from Hilly Fields and Mountsfield Park street trees; Victorian terrace shared drainage in New Cross and Deptford; Combined sewer capacity issues during heavy rainfall in the Ravensbourne catchment; Joint displacement in 1930s clay pipe drains from London Clay ground movement; Shared drainage disputes in Catford's Victorian terrace streets.
Victorian Terrace CCTV Survey and Repair — Deptford. Problem: A pair of adjoining Victorian terraces in Deptford, Lewisham, shared a drain that was blocking every few weeks. The neighbours had an ongoing dispute about who should pay for repairs. Solution: We conducted a CCTV survey of the complete shared drain run and produced a written report showing the location and cause of all defects. The main blockage source was a displaced joint beneath the shared rear gate — clearly on the shared section adopted by Thames Water in 2011. We provided the report to Thames Water, who attended and carried out the repair under their adopted sewer obligations. Result: Thames Water repaired the displaced joint at no cost to either homeowner. The neighbour dispute was resolved. Both properties have had no further blockages.
London Clay is one of the most problematic soils for underground drainage. We explain how the capital's geology causes drain damage and what you can do to protect your pipes.

The most common causes of blocked drains in London include: grease and fat build-up (fatbergs), root intrusion from London's many mature trees, collapsed or cracked Victorian clay pipes, flushed non-flushable items (wet wipes, cotton products), and ground movement from London Clay shrink-swell. London's Victorian drainage infrastructure is particularly susceptible to root infiltration and joint displacement.
