Shepperton has backwaters, islands and marinas along the Thames, and some of its property sits very close to the water.
Where a property sits on or beside an ait, a backwater or a marina channel, the water table can be very close to the surface. Drainage in that situation is often not straightforward gravity at all: it may be pumped, it may run a long way to reach anything public, and on some properties it is a private treatment system rather than a mains connection. Each of those fails differently, and the first useful question is which of them you have, because the answer changes the job. If nobody is sure, a CCTV drain survey will show it.
On the more conventional streets the housing is interwar and post-war on clay and concrete, where groundwater can get in through open joints. The area also has studio and light industrial sites, with yard gullies, interceptors and surface water systems that are easy to forget until heavy rain puts water where it should not be.
Waterside and island property often uses pumps or private treatment rather than gravity to a sewer. They fail differently.
Ground at or near the water line. Open joints take water in and the drain silts rather than blocking.
Studio and light industrial sites with surface water systems that need checking before they flood.

Sewage backing up, drains overflowing, or a home or business you cannot use until it is fixed. Phone answered 24/7.
Scours grease, silt, scale and roots off the pipe wall, rather than just making a hole through the blockage.
See the inside of the pipe: recurring blockages, pre-purchase checks, insurance and subsidence claims.
Cracked joints, root damage and collapsed sections, repaired without digging where the pipe allows.
Restaurants, pubs, offices, landlords and managing agents: planned maintenance and out-of-hours call-outs.
Leaks, taps, traps, toilet cisterns and waste pipes: the plumbing that often comes with a drainage job.
Common questions about drainage in Shepperton, answered for the kind of property you find there.
The pump, the non-return valve, or the rising main, rather than the pipe itself. A seized or tripped pump stops drainage completely because there is no gravity fallback. A jammed non-return valve lets the system back up towards the property. Both are urgent in a way a slow drain is not, and both are worth checking before assuming a blockage.
Deeds and searches usually say, but the practical test is whether there is an inspection chamber running towards a public sewer or a tank and soakaway on the plot. Tell us what you can see when you call. It matters, because on a private system there is no water company to fall back on and the whole thing is your responsibility.
