Drain Jetting in Lewisham
Lewisham's dense urban fabric (SE13–SE16) includes numerous Victorian and Edwardian buildings now used as restaurants, cafes, shared houses, and offices on Thames Water's separate sewer system, all generating high drainage volume. Regular drain maintenance in Lewisham is not optional—it is a legal obligation for landlords and commercial operators under Thames Water bylaws.

Drainage in Lewisham — what local engineers know
Lewisham is a high-density area with concentrated commercial and residential properties sharing aging Victorian-era drainage infrastructure. Restaurant kitchens and takeaways in Lewisham produce grease buildup that hardens in pipes during cool overnight hours, forming partial blockages. HMO landlords operating multi-occupancy properties in Lewisham face heavy toilet and shower drainage; combined with the separate sewer system in most SE14 and SE15 postcodes, drain loads can overwhelm Victorian pipes. Thames Water and Greenwich Council expect property managers in Lewisham to maintain drains proactively. Monthly or quarterly drain flushing in Lewisham removes grease, scale, and sediment accumulation, preventing emergency call-outs and keeping properties compliant with regulatory expectations.
- Hard water supply causes limescale accumulation in boilers, radiators and soil pipe joints — powerflush and descaling demand is high across Lewisham
- Separate sewer system across most of Lewisham: misconnections (e.g. washing machines plumbed into surface water drains) are a known local issue and can result in environmental enforcement action
- Ageing infrastructure in parts of Lewisham means drain blockages from grease, wipes and root ingress remain the most common call-out reasons
- With 32% of properties built before 1920, salt-glazed clay drainage and lead-solder copper pipework are common — pipe collapse, root ingress and joint failure are recurring call-out drivers.

Who's responsible for drains in Lewisham?
In Lewisham, responsibility for a blocked or damaged drain depends on where the fault sits. As a homeowner you are responsible for the drains within your property boundary that serve only your home. Since the 2011 private sewer transfer, Thames Water is responsible for shared sewers and lateral drains beyond your boundary — even where they run under private land. Road gullies and highway drainage are maintained by Greenwich.
This matters because it determines who pays. If our engineer's CCTV inspection shows the fault is in a shared sewer, we'll tell you — and you can report it to Thames Water rather than paying for the repair yourself. The separate sewer layout that dominates Lewisham affects where these boundaries typically fall, and our local engineers know the SE13, SE14, SE15 networks well enough to identify ownership quickly.
