Installing & Maintaining Soakaways Throughout Dorset, Hampshire, Somerset & Wiltshire
Soakaways are essential drainage systems designed to manage excess water, thereby preventing flooding and waterlogging. These systems work by channelling water into a designated pit filled with porous materials, allowing it to gradually seep into the surrounding soil. At Smart Drainz, we handle the installation, maintenance and repair of both rainwater and septic soakaways for properties across Bournemouth, Southampton, Salisbury, Portsmouth and all other locations in Dorset, Hampshire, Somerset, Surrey, West Berkshire, West Sussex, and Wiltshire.
This complements services such as 24/7 assistance with blocked drains and burst pipes, and CCTV surveys that map out and diagnose faulty systems, to make us a truly versatile drainage contractor and one-stop solution for all your drainage requirements.

Types of Soakaways We Install
- Rainwater Soakaways: These systems are designed to manage surface water, such as rainfall, by diverting it away from buildings and paved areas.
- Septic Soakaways: These are specifically constructed to handle wastewater from septic tanks, filtering and dispersing it safely into the ground.
Whether you need a rainwater soakaway for an urban home in Bournemouth or Southampton, or septic soakaway for a rural property outside of Portsmouth or Salisbury, we’re a drainage contractor with the expertise necessary to deliver effective and long-lasting solutions.


Why Are Soakaways So Important?
Soakaways play a vital role in maintaining a property’s drainage system, especially in areas prone to heavy rainfall or poor soil drainage. They help to:
- Prevent Flooding: By managing excess water, soakaways reduce the risk of flooding on your property.
- Protect Foundations: Diverting water away from buildings helps to prevent structural damage caused by waterlogging.
- Environmental Benefits: Soakaways promote natural water filtration, reducing pollutants before water re-enters the ecosystem.
The Science Behind Soakaways
Soakaways work on the principle of infiltration. The pit’s porous materials allow water to disperse gradually, reducing surface runoff and promoting soil absorption. For septic soakaways, an additional filtration layer ensures that only clean water is released into the surrounding area, making them an environmentally friendly solution.
How We Install Soakaways
At Smart Drainz, our soakaway installation process is meticulous and tailored to each property’s unique needs. Serving Bournemouth, Southampton, Salisbury and Portsmouth, we follow these key steps:
1. Initial Percolation Test:
This test determines soil permeability, ensuring the soakaway can effectively manage water. It also helps us calculate the size and depth required for optimal performance.
2. Planning & Design:
Our team designs soakaways to comply with regulations, ensuring they are positioned at a safe distance from building foundations and property boundaries.
3. Excavation & Installation:
We excavate the site and fill the pit with porous materials such as gravel or specialised soakaway crates. For septic soakaways, we incorporate additional filtration layers.
4. System Testing:
Once installed, soakaways are tested to confirm its efficiency in managing water flow.

Regulatory Considerations
Soakaway installations are governed by the Environment Agency and Building Regulations to ensure safety and environmental compliance. At Smart Drainz, we ensure all our installations meet these strict standards.
Key Points We Consider:
- Location: Soakaways must be positioned at least 5 metres from any building.
- Capacity: The system must handle the expected volume of water, determined through percolation testing.
- Permits: Septic soakaways may require additional permits depending on local regulations.
We back all our soakaway installations with a 10-year guarantee, providing peace of mind for property owners in Bournemouth, Southampton, Salisbury and Portsmouth.
