Why drains block in Lewisham, and what we do about it
The Rivers Ravensbourne and Quaggy run through the heart of the borough and meet at Lewisham town centre. Much of Lewisham famously flooded in 1968. Today the council's preliminary flood risk assessment identifies the Ravensbourne corridor between Catford and Lewisham as a critical surface water drainage area, where rain from the surrounding streets gathers.
The same assessment says Sydenham and Forest Hill could see the biggest increase in people at risk from surface water as rainfall gets heavier. The council has been working on schemes at Wells Park in Sydenham and Verdant Lane to reduce surface water flooding, and planting street trees to soak up more rain.
Victorian terraces and shared runs
Brockley, Ladywell, Hither Green and Catford are full of Victorian and Edwardian terraces, many with one drain run serving several houses. A blockage in a shared run can affect your neighbours too. Clay pipes of that age also let roots in through cracked joints.
New homes in Deptford and Lewisham
Large new developments in Deptford, New Cross and around Lewisham Gateway have modern drainage that mostly blocks with wipes, fat and debris rather than roots. Whatever the age of your building, we find the cause with a camera and show you what we found.
Is it your drain or Thames Water's?
Thames Water is responsible for flooding from the public sewer network in Lewisham, both foul and surface water. A drain serving only your property, inside your boundary, is usually yours. If the blockage is on the public side, we'll tell you so you can report it.

My neighbour's drain is blocked too. Is it the same problem?
It may be. Many terraced houses in Lewisham share a drain run before it joins the sewer, so one blockage can affect several homes. We can trace it with a camera and tell you where it is and who's responsible.
Do you cover Forest Hill and Sydenham?
Yes. As well as Lewisham and Catford, we cover Deptford, New Cross, Brockley, Ladywell, Hither Green, Lee, Forest Hill, Sydenham, Bellingham and Downham.
Do you unblock drains in converted flats?
Yes. Converted houses often share one stack and drain between several flats. We find which flat or run the blockage is in and tell the landlord or managing agent what we found.
Why does my drain overflow in heavy rain but work the rest of the time?
It's usually partly blocked and can't cope with the extra water, or the sewer it joins is overloaded. A camera check tells us which. We clear a partial blockage on the day.
Do you clear drains for restaurants and takeaways in Lewisham?
Yes. Commercial kitchens are a common source of fat blockages. We clear the drain, check it with a camera and can set up regular jetting to stop it recurring.
