Expert Soakaway Installation in Wigan
Your trusted local experts for all drainage and soakaway solutions.

Installing a new commercial soakaway requires precise engineering, accurate calculation, and structured execution. Our expert engineers follow a meticulous step-by-step process to ensure your system performs flawlessly for decades. We begin by assessing your site's unique requirements, looking closely at your current surface water management and identifying any potential issues.
First, we carry out comprehensive site surveys, which often include high-definition CCTV drain surveys of your existing pipe infrastructure to check for blockages, root intrusion, or structural defects. We also perform a mandatory soil percolation test in accordance with British Standards. This test measures how quickly the ground absorbs water, ensuring the soil chemistry and water table levels are suitable for an infiltration system.
Next, our design team calculates the correct capacity based on your site's total impermeable surface area and historical rainfall data for the North West. We then excavate the area using specialized machinery, laying down high-load attenuation crates wrapped in professional geotextile membrane. This membrane is critical as it prevents silt and debris from entering the system while allowing clean water to disperse safely back into the ground. Finally, we backfill the area, restore the surface to its original state, and provide you with a comprehensive sign-off report.

Standing surface water is more than just an eyesore; it is a major liability for any North West business. Flooded car parks and access roads can deter customers, damage delivery vehicles, and create dangerous slip hazards that leave you open to insurance claims. By investing in a professional soakaway installation, you eliminate these pooling issues and protect your hard-earned business reputation.
Choosing an engineered soakaway also prevents water from pooling near your building's foundations. Over time, standing water can seep into masonry, causing expensive damp issues, structural erosion, and concrete degradation. A properly installed system channels this water away instantly, preserving the long-term value of your property asset.
Additionally, managing water on-site rather than discharging it directly into public sewers significantly reduces your trade effluent costs. Water authorities charge businesses heavily for surface water drainage based on site area. By disconnecting your surface water run-off from the public grid, you can enjoy substantial long-term savings on your utility bills.

Commercial drainage is strictly regulated in the UK, and failing to comply can result in heavy fines from the Environment Agency or local water authorities like United Utilities. Under Building Regulations Part H, surface water must be managed as close to its source as possible. This makes soakaways and sustainable drainage systems the legally preferred option over public sewer connections.
Our commercial soakaway installation services comply fully with CIRIA C753 (The SuDS Manual) and British Standards BS EN 752. We ensure that your system is positioned at least five metres away from any building or road to protect structural integrity. We also take into account the local geology, ensuring your system does not interfere with nearby groundwater protection zones.
If your site handles vehicles, such as a logistics depot, distribution yard, or fuel station, we integrate oil interceptors and silt traps into the drainage design. This prevents hazardous hydrocarbons and chemicals from polluting the local water table during heavy rain. Working with us means you get a fully compliant, risk-free installation that meets all modern environmental standards.
