Nottingham sits on soft sandstone by the River Trent. Both shape how drains behave here. A blocked drain still shows up the same way it does anywhere, with water that will not go down. This page runs through what blocks drains here, which pipe is whose, and how to get free quotes from drainage firms near you.

Common signs of a blocked drain in Nottingham

Blockages usually give warning before they overflow. Watch for these:

• Slow draining. Sinks, baths and toilets take much longer to empty than normal.
• Gurgling. A plughole or toilet bubbles when water drains somewhere else in the house.
• A smell outside. A drain smell near a gully or manhole means waste is sitting in the pipe.
• An outside drain filling up. If the yard gully or a manhole rises, the blockage is downstream and needs clearing.
• More than one fitting affected. A sink and a toilet backing up together points to the shared pipe.

One slow sink can sit until a booked visit. A toilet that has stopped clearing, or water rising out of a drain outside, needs dealing with straight away.

What people typically pay in Nottingham (2026)

Local drainage companies in Nottingham advertise from around £60 for a straightforward daytime unblocking of one drain. A blockage that needs jetting costs more. An evening, weekend or emergency visit costs more again. A camera survey to find a repeat problem is a separate job.

Price depends on the time of day, how deep the blockage sits and whether digging is needed, so a quote for your drain is the figure that counts. See our guides to drain unblocking cost and CCTV drain survey cost for more.

The River Trent and Nottingham’s flood defences

The Trent has flooded Nottingham badly before. In March 1947 the river affected 28 miles of road, 3,000 properties and 86 factories across the city. The autumn 2000 floods were another close call. After that, the Environment Agency built the Nottingham Left Bank scheme, a 27 kilometre line of defences running from Sawley to Colwick. It opened in September 2012 at a cost of around £45 million and protects about 16,000 homes and businesses. It was the largest inland flood defence scheme in the country by the number of properties it protects.

The Meadows, the low ground between the city centre and the river, is the part that always sat most exposed to the Trent. Those defences hold the river back now, but they do nothing for the drain in your garden. When the ground near the Trent is soaked and the river is high, a drain that is already part blocked has nowhere to send its water and backs up into the house. If your drain floods whenever the river is up, the pipe is usually part blocked rather than simply overwhelmed. A camera survey shows which.

Built on sandstone with caves beneath the city

Nottingham stands on Sherwood Sandstone, which is soft enough to cut with hand tools. That is why more than 800 man made caves have been recorded under the city, dug over the centuries as cellars, homes and workshops, with more found every year. Many older properties in the centre have a cellar cut straight into the rock, and pubs like Ye Olde Trip to Jerusalem still use the caves today. The City of Caves at Broadmarsh is a set of them opened to visitors.

The sandstone is permeable, so water tends to move down through it rather than sit on top. That is a help in normal weather. A cellar cut into rock can still flood if the drain serving it cracks or blocks, because the waste has nowhere to go. A property with a sandstone cellar that floods or smells almost always has a drainage fault rather than rising damp. A camera survey finds the broken section.

The River Leen, culverted since 1863

The River Leen runs down from the Robin Hood Hills through Bulwell, Basford, Radford and Lenton, and joins the Trent by The Meadows. Much of it was put into a culvert in 1863. As the area around it was built up, the run off got faster. It flooded badly in 1960.

Where an old watercourse has been culverted and built over, the drains laid across that ground can crack or drop at the joints as it settles. That is one reason older streets in Radford, Basford and Lenton get blockages in the same spot again and again. Clearing the blockage helps for a while. A survey shows whether the pipe itself needs repair.

Victorian terraces and the old courts of St Ann’s

St Ann’s was built up after 1845 as a dense grid of Victorian terraces, once arranged in courts of ten houses with shared toilets and open sewers. Slum clearance from the 1930s to the 1970s cleared most of it, and it was rebuilt as a modern estate, so the drains under the newer housing are far younger than the streets around them.

It is a useful contrast for the rest of Nottingham. Where the original Victorian terraces survive, in areas like Radford, Sneinton and Hyson Green, the drains are old, often shared along the back of a row, and more likely to have cracked or root damaged pipe. A drain shared between several terraced houses is usually the water company’s, not yours.

Tree roots and clay pipes in the older suburbs

The leafy older suburbs, Mapperley, Sherwood and Carrington among them, have mature street trees and Victorian or Edwardian clay drains. Roots are drawn to the small amount of water and air that seeps from a cracked joint, and once a root gets in it grows into a mat that catches everything passing through. This is one of the most common causes of a repeat blockage in these areas.

Rodding clears the root for a while, but it grows back unless the joint is repaired. A camera survey shows where the root is getting in, so a local company can cut it out and reline or repair that section rather than returning every few months.

Student and shared houses in Lenton and Dunkirk

Lenton and Dunkirk, next to the university, are some of the most concentrated student areas in the country, mostly older terraces let room by room. A full house puts far more through a drain than a family home, and wipes and cooking fat from a shared kitchen block a pipe faster than they would elsewhere.

If you rent one of these houses, a blocked drain is the landlord’s to clear, so report it early. A slow drain caught in time is a simple job. Left until it overflows, it becomes an emergency, and in a terrace it affects the houses either side too.

Who looks after the drain in Nottingham

Different pipes have different owners in Nottingham:

• Your own drains. Pipes inside your boundary serving only your home are yours to maintain, cellar drains included.
• Severn Trent. Shared pipes, and pipes beyond your boundary that run to the public sewer, are Severn Trent’s, on 0800 783 4444, day or night. If they find the blockage is private, they will tell you and suggest an independent company.
• The council and the Environment Agency. A blocked road gully is looked after by Nottingham City Council, which also handles surface water flooding. Flooding from the Trent is the Environment Agency’s.

If you are not sure whose pipe is blocked, a local drainage company can usually tell from where the water backs up. They will say if it is one for Severn Trent to clear at no charge.

FAQs in Nottingham

My sandstone cellar has flooded. Is it groundwater?

Sandstone lets water drain down through it, so a flooded cellar in Nottingham is usually a drainage fault rather than rising groundwater. A camera survey shows whether a drain serving the cellar has cracked or blocked.

Why does my drain flood when the Trent is high?

A drain that only backs up when the river is up is normally part blocked already. It manages in dry weather, then cannot cope when the ground is soaked. A survey shows whether the pipe is blocked, cracked or holding water.

My drain blocks every few months in the same place. Why?

A repeat blockage in the same spot is usually a tree root getting in at a cracked joint, common in the older tree lined suburbs. Rodding clears it, but it grows back until the joint is repaired. A survey shows where to fix it.

Several houses in our terrace keep blocking. Whose drain is it?

A drain shared along the back of a terrace is usually Severn Trent’s. Report it to them on 0800 783 4444 before paying for a private clearance.
