Underground Sewer Pipes

Large diameter underground sewer pipes are the workhorses of drainage systems designed to handle significant volumes of water. Here at Drainage Sales, we offer a robust selection of pipes built to tackle demanding applications. Manufactured to BS EN 1401 - 1 standard, these solid wall adoptable sewer pipes offer exceptional durability, strength, and resistance to chemicals and corrosion, guaranteeing a long lasting and reliable drainage solution.

Large-scale projects: Accommodate the extensive drainage needs of commercial buildings, industrial facilities, and large residential developments.
High-flow situations: Efficiently transport wastewater from factories, processing plants, and areas with heavy water usage.

Large Sewer Pipes for Every Project

To meet the unique needs of every project, we offer a wide range of underground sewer pipes in various diameters to ensure you find the perfect fit.

200mm Drainage Pipe: 200mm diameter drainage pipes are a powerful solution for managing wastewater disposal. Compared to our selection of 110mm and 160mm pipes, 200mm pipes boast a significantly larger capacity, efficiently handling higher volumes of water.
250mm Drainage Pipe: Ideal for larger domestic projects or commercial settings with increased wastewater volume, this size can accommodate multiple fixtures and higher flow rates.
315mm Drainage Pipe: This substantial pipe size is suitable for commercial or industrial drainage systems that require the capacity to handle significant wastewater volumes.
400mm Drainage Pipe: Our largest diameter pipes are built for heavy duty applications in large industrial facilities and large scale residential projects where substantial wastewater disposal is necessary.

Diverse Applications of The Sewer Pipe

Large underground sewer pipes have a variety of applications, primarily focused on handling significant volumes of wastewater and stormwater:

Large Scale Projects:

Commercial Buildings: Large office buildings, shopping centres, restaurants, and hotels all generate significant wastewater that needs efficient removal. Large diameter sewer pipes ensure smooth flow and prevent backups.
Industrial Facilities: Factories, processing plants, and other industrial settings often produce large volumes of wastewater with potential contaminants. These pipes can handle the increased flow and resist degradation from chemicals.
Large Residential Developments: Apartment complexes, student housing, and other high density housing projects require robust drainage systems. Large pipes ensure all units can drain efficiently.

High Flow Situations:

Wastewater Treatment Plants: These facilities receive large volumes of wastewater from various sources and require pipes that can handle the influent efficiently.
Stormwater Management: Large diameter pipes are crucial for channelling significant rainwater runoff from large areas like parking lots, airports, and industrial sites. They prevent flooding and protect infrastructure.
Agricultural Drainage: In some cases, large diameter pipes are used to drain excess water from fields, especially in areas with high rainfall or clay soil.

Features & Benefits of Underground Sewer Pipes

Our underground sewer pipes are built to endure, offering a multitude of benefits:

Durability:

Manufactured from high density uPVC material, our underground drainage pipes are built to withstand the rigours of underground installation and resist corrosion for a long lifespan. Our underground sewer pipes are certified to BS EN 1401-1, ensuring they meet the highest standards for quality and performance.

Strength:

Large sewer pipes can handle significant pressure and weight from surrounding soil, ensuring they won't crack or collapse under load.

Leak-Proof Design:

Featuring watertight joints and connections, our pipes minimise the risk of leaks that could contaminate soil or groundwater, protecting the environment. Our sewer pipes feature a unique captive lip seal within the sockets. This innovative design simplifies installation and ensures a secure, watertight connection every time. The seal prevents displacement, reducing the risk of leaks and ensuring a long lasting, trouble free drainage system.

Smooth Interior:

The smooth internal surface allows for optimal wastewater flow, reducing blockages and the need for frequent maintenance, saving you time and money.

Chemical Resistance:

The sewer pipes are resistant to common chemicals found in wastewater, preventing degradation over time and maintaining structural integrity.

Easy Installation:

The underground sewer pipes are designed for ease of installation, often featuring solvent weld or push-fit connections that require minimal specialist tools, streamlining the process.

Installation Support: From Guides to Experts

Benefit from comprehensive installation guides and expert advice from our knowledgeable team. Whether you require assistance with selecting the right pipe diameter or navigating the installation process, we're here to help.

If you have any questions that aren’t answered in the installation guide, or if you are interested in our large underground sewer pipes, get in touch with our team with more details of your project to see how we can help.

*Delivery to non-Industrial Scotland, Northern Ireland, and CH, LL, and CA postcodes can sometimes take slightly longer, although this is dependent upon the exact location.

If we are unable to deliver your order within the above timeframe for any reason, we will contact you to arrange an alternative delivery day. We use overnight carriers, so we are unable to arrange or confirm an exact time of delivery.

Some special or non-stocked items on our website have extended lead-times, which are displayed on the product pages in question – see below for more details.

Whilst every reasonable effort shall be made to keep to a delivery date, we cannot be held liable for any losses, costs, damages, or expenses arising directly or indirectly out of any failure to meet any estimated delivery date.

In the unlikely event of a late delivery, we will be unable to compensate you for any consequential loss, so please do not organise any plant or labour before you have received your materials.

DELIVERY CHARGES AND EXTENDED LEAD TIMES

Orders over £1,000 excluding VAT will be delivered free of charge. Orders under this amount will incur a charge of £15.00 + VAT. This applies to most stocked items and some items that are supplied directly from manufacturers. Orders of stocked items are generally delivered in 1-3 working days.

Some stocked items will incur a bulky or pallet charge due to their extreme weights or lengths:

Bulky items - £45.00 + VAT charge placed on orders that contain one or more bulky products. These items will be marked as bulky during the checkout process.
Palletised items - £60.00 + VAT charge placed on orders that contain one or more items that need to be sent and delivered via a pallet. These items will be marked as palletised during the checkout process.

A full list of stocked items can be found here.

Certain items, usually those sent direct from manufacturers, incur additional delivery charges and an extended lead time regardless of the order value, due to the restrictions placed upon us by our carrier and the extreme weights/lengths. These charges are applied instead of the standard £15.00 + VAT charge if the order is valued under £1,000 excluding VAT.

The following product ranges have extended lead times or incur additional delivery charges. Please click on each individual range for specific details.

SPLIT DELIVERIES

If you have ordered a mixture of goods that come both from us and direct from our manufacturing partners, you will be advised of this in your dispatch email. As the order is coming from two locations, you will receive two different deliveries. Delivery on direct items can have extended lead times and will need someone present to check and sign for the goods.

Occasionally, we don't have all items in stock at our main warehouse. If this is the case, we will endeavour to send the stock the same day from one of our other branches, in order to not delay delivery of the complete order. This may lead to a split delivery, dependant on the courier being used. We will contact you if there is going to be a delay due to this.

LABOUR AND MACHINERY

Please do not book machinery or labour until your goods have been received and checked over. Whilst every effort is made by our couriers to deliver your parcel within the stated timeframe, Drainage Sales cannot be held responsible for any additional costs incurred by delays outside of our control.

CHECKING AND SIGNING FOR ORDERS

SIGNED FOR POLICY – T&CS

All orders should be signed for. If you are unable to sign for your delivery, you can arrange with us for a neighbour to take delivery of your order. You can also advise us of a safe place where your order can be left, although we cannot take responsibility for any shortages or obvious damages.

Please ensure that you always check the number of packages that you are signing for. If there is an incorrect number of packages or any package appears damaged, you should note this on the signature panel and advise us so that we can rectify the issue as quickly as possible. Once goods have been signed for as being received ‘complete and in good condition’, any claims are not covered by the carrier’s insurance company.

Signing for goods as ‘unchecked’ makes any claims inadmissible, so please check the number of packages and look for any signs of any damage, noting any issues on the signature panel. Although the delivery drivers are busy, they are contractually obliged to wait whilst you check your delivery.

WHAT IF I CAN’T WAIT IN ALL DAY?

There is a ‘Notes’ section of the Basket review page where you can request for your goods to be left in a safe location – just tell us where to leave the order. Please not that we cannot take responsibility for any shortages or obvious damages if goods have not been signed for.

Please note that deliveries made by DHL (these are generally small orders with no pipe or bulky products) cannot be left in a safe location. You will be advised which carrier will be delivering your order by email at the point of dispatch.
