Brands like Hunter, Brett Martin, ULTRA3 offer domestic property sewer pipes in 110mm and 160mm diameters. For heavier duty options large diameter sewer pipes offer 200mm up to 400mm cost-effective underground sewer pipes.

Land Drain Pipes
Land drain pipes, also known as land drain coils, are used for all types of commercial and agricultural purposes, typically for creating French drains and soakaway or attenuation systems. In both perforated and unperforated coils, lengths of 25m and 50m are available in 5 diameters to allow installers to dictate in part the rate of water flow. Land drain pipes are available in 60mm, 80mm, 100mm, 160mm and 200mm diameters.
| Diameter | Price (from Ex.VAT) |
| 80mm land drain pipes | £50.00 |
| 100mm land drain pipes | £60.00 |
Twinwall Surface Water Pipes
Twinwall surface water pipes have a smooth inside for water flow and a rough outer side to combat any damage that might be done on-site. With a smooth inside there won’t be any silt accumulation. Perforated or unperforated for soakaway and attenuation capabilities, twinwall pipes come in a variety of diameters. Twinwall pipes come in 150mm, 225mm, 300mm, 375mm, 450mm and 600mm diameters.
| Diameter | Price (from Ex.VAT) |
| 150mm twinwall pipes | £28.75 |
| 225mm twinwall pipes | £62.50 |
| 300mm twinwall pipes | £108.33 |
| 375mm twinwall pipes | POA |
| 450mm twinwall pipes | POA |

MDPE Water Supply Pipes
Whether it’s a blue water supply pipe or a black water supply pipe, all of the water supply pipes available from Drainage Superstore are manufactured from stress-resistant MDPE. Bluewater pipes are for potable drinking water and black water pipes are for transporting non-consumable water such as seawater or foul water. It’s important not to get the two confused. Bluewater pipes also have the added benefit of being able to be used for water service connections between mains and domestic residences. Water pipes come in 20mm, 25mm, 32mm, 50mm and 63mm diameters.
| Diameter | Price (from Ex.VAT) |
| 20mm water supply pipes from | £18.00 |
| 25mm water supply pipes from | £34.65 |
| 32mm water supply pipes from | £57.75 |

Cast Iron Underground Drain Pipes
Cast iron underground drain pipes are quiet, 100% recyclable, non-combustible, and have high tensile strength. It’s mandatory to have cast iron drainage in certain applications thanks to the strength and minimal maintenance needed. In 100mm, 150mm, 200mm, 250mm, 300mm and 400mm diameters, cast iron drain pipes cost less than you may think.
