Drain Installation in Manchester & Greater Manchester

New drainage installations are required whenever a property is extended, reconfigured, or developed in a way that creates new drainage requirements. Whether you are building a single-storey rear extension in Leigh, fitting out a loft conversion in Worsley, creating a new driveway in Salford, or developing a new build property anywhere across Greater Manchester, Kamdem HomeTech’s drainage specialists design and install drainage systems that perform reliably and comply with current Building Regulations.

We plan drain installations carefully before any groundwork begins — calculating falls, sizing pipes correctly for anticipated flows, and confirming connection points to the existing drainage system. Working alongside builders, groundworkers, and architects, we ensure drainage is installed to the right standard at the right stage of the project.

What Is Drain Installation?

Drain installation covers the design and construction of new drainage systems — both foul water drains (carrying waste from toilets, sinks, and appliances) and surface water drains (managing rainwater from roofs, driveways, and paved areas). Getting the design right is critical: pipes must be laid at the correct gradient to ensure self-cleansing flow, and connections to the existing drainage system or public sewer must be made in accordance with the relevant regulations.

In Greater Manchester, new drainage installations connecting to the public sewer network require notification to United Utilities under the relevant Building Regulations. Where planning permission is involved, sustainable drainage system (SuDS) requirements may also apply. Kamdem HomeTech advises on these requirements and can manage the notification process where required.

Frequently Asked Questions — Drain Installation in Manchester

Do I need Building Regulations approval for new drain installation in Manchester?

Yes. New drainage installations in England must comply with Part H of the Building Regulations, and work is subject to Building Control inspection. Where new drainage connects to a public sewer, notification to United Utilities is also required. Kamdem HomeTech advises on the specific requirements for your project and can manage notifications where appropriate.

How deep do drain pipes need to be laid in Greater Manchester?

Drain pipe depth depends on the location and function. Domestic foul water drains are typically laid at a minimum depth of 600mm below ground level in garden areas, and at least 750mm where subject to vehicle loading. Surface water drains may be shallower in some circumstances. We ensure all pipe depths comply with current standards for the specific installation.

What gradient is required for drain pipes in Greater Manchester?

The minimum recommended gradient for 100mm (4 inch) foul drains is 1:40 (approximately 25mm fall per metre of pipe run). For 150mm pipes, a minimum of 1:150 is acceptable, though steeper gradients are preferable for foul water. Surface water drains can be installed at shallower gradients. Getting this right at installation is critical — incorrect falls lead to sediment accumulation and blockages.

Can you install a soakaway for surface water drainage in Greater Manchester?

Yes. Soakaways are a commonly used surface water disposal method for properties in Greater Manchester where connection to a public surface water sewer is not practical or permitted. We size soakaways correctly for the drainage area they serve and install them in accordance with current guidance. Soakaway suitability depends on soil permeability — we carry out a simple percolation test where required.

How long does drain installation take for a property extension in Manchester?

The drainage element of a typical single-storey extension — including connection to the existing system, below-ground pipework, and an inspection chamber — typically takes one to two days. Larger projects — including new build drainage systems or complex surface water schemes — take longer and are phased alongside the wider construction programme.
