Drains in Merton: what our engineers see
Merton has two quite different halves when it comes to drains. Around Wimbledon, South Wimbledon and Colliers Wood you find Victorian and Edwardian terraces with clay pipes, whereas Morden, Raynes Park, Motspur Park and parts of Mitcham were largely built up between the wars. Drains from that era are now close to a century old, and cracked joints or settled sections that hold water and debris are common findings.
Another feature of interwar estates is the shared drain. Semi-detached and terraced houses were often connected along a single run behind the gardens before joining the sewer. Since 2011 most of those shared sections have been Thames Water's responsibility, but the branch from your own house is usually still yours, so finding exactly where the blockage sits matters.
The River Wandle runs through Colliers Wood, Merton Abbey Mills and Mitcham, and the Beverley Brook skirts Raynes Park and Motspur Park, so some low-lying streets can be slower to drain during heavy rain. The borough is also green, with Wimbledon Common, Mitcham Common and many tree-lined roads, meaning roots in drains are a regular find on our camera surveys. On the high streets of Wimbledon, Morden and Mitcham, takeaways and restaurants should keep grease traps maintained to avoid blocked drains.

My 1930s semi shares a drain with next door. Who pays to clear it?
In most cases a drain shared with neighbours became Thames Water's responsibility in October 2011, so you can report a blockage in the shared section to them. The part serving only your home, inside your boundary, is usually your responsibility. If you are not sure which section is blocked, we can lift the covers and check before any work is done.
What causes a smell from the drains in my garden?
A drain smell usually comes from waste sitting in a partly blocked pipe or a chamber that is not draining properly. It can also come from a cracked pipe or a dried-out trap. We check the chamber, clear any blockage with jetting, and run a camera through the pipe if the cause is not obvious, so the smell does not keep returning.
Can you help with a blocked drain in a rented flat in Wimbledon?
Yes. We work with tenants, landlords and letting agents. Landlords are usually responsible for the drains in a rented home, although a tenant may be asked to pay if the blockage was caused by wipes or fat. Check your tenancy agreement, then let your landlord or agent know, and we can attend and report back to them.
