Rainwater retention tank with reuse pump and sprinkler system at residential area




Attenuation systems are crucial to a comprehensive approach to stormwater management. Huge underground tanks provide dedicated storage for excess runoff while control units delay the flow of water into public networks — minimizing the risk of overflows and floods.

The cleaned runoff can then be stored to provide drought relief for non-potable applications such as bathroom facilities and landscape irrigation during dry spells.

To meet your specific project requirements, we offer a comprehensive design service that ensures your solution is tailored to your space, conditions and surroundings. Discover how you can turn flood prevention into a water shortage solution with a Pipelife attenuation system.

The Stormbox can be tailored to your space and easily connected to pipes, cleaning tanks, manholes or inspection chambers.  

Pipelife Stormbox soakaway crates for infiltration and attenuation


For deep installations beneath heavily trafficked areas, we have created a robust attenuation crate with extremely high vertical- and lateral-load resistance. Integrated push-fit connections streamline installation while an innovative wall design prevents foil damage during high-pressure cleaning. Stormbox II is perfect for large-scale commercial or industrial projects where load resistance, depth, fast installation, and easy maintenance are critical.

We also offer Stormbox II E as an eco-friendly alternative. Composed of 100% recycled PP, the Stormbox II E boasts similar qualities to the Stormbox II while minimizing your project's carbon footprint. 

Sealed large size corrugated pipe


Alternatively, we also offer storage tanks made of sealed large-diameter pipes. These PP pipes can retain vast quantities of rainwater underground while withstanding significant vertical and lateral pressures.

The pipes are easily connected with push-fit sockets for fast installation. They are also compatible with a wide range of fittings to meet various project requirements.

Manholes with flow control units vortex and orifice


Flow control units limit the outflow of attenuated water when discharging to public networks. Our orifice control system limits the flow rate by forcing the water to go through a smaller hole than the original outlet.

We also offer vortex control units that cause the outflowing water to form a vortex as it travels. This reduces the discharge rate, and subsequent pressure on the public network, to an even greater extent.

Each control unit can be tailored to meet the specific flow rate requirements of your project and local network.


Attenuation systems are valuable additions during extreme rainfall events and dry summer months. Discover how our tailored solutions can protect your property while supporting circular water management practices.

Frequently Asked Questions

Stormwater management system thumbnail

Attenuation systems are vital for effective stormwater management. Robust plastic crates or large-diameter pipes are linked together to create vast retention and attenuation tanks that are installed entirely underground. To ensure safe long-term storage, the pipes are interconnected, and the crates are encased in a watertight foil. From here, the rainwater can be safely discharged to public networks or reused for non-potable applications during droughts.

While infiltration and attenuation systems are made from similar components, they serve different functions depending on the needs of the user:

Attenuation systems are large underground storage tanks that detain and retain rainwater. Stormbox crates or large-diameter pipes are connected to create an extensive underground sealed tank. This dedicated storage not only prevents flooding and overflows but creates a reservoir of reusable water for non-potable applications, such as bathroom facilities, car washing, irrigation or firefighting.

Infiltration systems are similar in design, but instead of retaining collected rainwater, they enable its gradual infiltration into the ground. Stormbox crates are encased in a water-permeable geotextile which prevents soil from entering the system, but freely allows water to pass into the soil. The system provides underground space for excess rainfall to accumulate until the surrounding soil is ready to accept it.

In many cases, infiltration and attenuation systems can work together to create a comprehensive and sustainable water management solution that provides both flood protection and drought relief.

Important aspects such as soil characteristics, the location of your property, and local vulnerabilities to floods or droughts can determine the type of system you require. Consult our experts to understand which system best suits your needs.

Those in sealed urban environments or remote areas without access to public networks will benefit most from an infiltration system.

In the urban context, infiltration systems allow for the completion of natural water cycles despite surface sealing. This helps to establish hydraulic invariance, maintaining groundwater resources and avoiding subsistence.

In remote locations that lack access to public networks or water bodies, infiltration systems provide a safe and controlled way to drain excess water directly into the soil.

Alternatively, attenuation systems will be preferable for areas that experience droughts and/or have impenetrable soils. 

For example, clay can prevent water from successfully infiltrating through the soil. Therefore, an attenuation system that stores rainwater for controlled discharge into public networks will be better suited to this environment.

Similarly, if your property is located in an area that is vulnerable to water shortages, having a store of reusable rainwater for non-potable applications, such as irrigation and bathroom facilities, can be particularly advantageous.

When heavy rainfall or snow melting occurs, public stormwater and sewerage systems can quickly become overcharged as such significant quantities of water enter the system over a short period of time. This often results in these systems overflowing, which can lead to flooding and the uncontrolled movement of polluted water. This has devastating effects on the environment and local water sources.

Attenuation systems minimize this problem by providing dedicated underground storage for excess rainfall or meltwater. They also reduce the water flow rate into the network, which alleviates pressure on public systems and reduces the likelihood of overflows.

Beyond this, attenuation systems allow users to engage in the sustainable practice of rainwater harvesting and reuse. Retained rainwater can be stored for non-potable applications during droughts, such as lawn irrigation or bathroom facilities, and conserves valuable drinking water resources. 

We offer a comprehensive consultation service with our design team to ensure your system is perfectly aligned with the needs of your property. By analyzing flood-risk calculation software, weather data and soil characteristics, we ensure your setup is optimized for the local environment as well as surrounding infrastructure.

This service is particularly advantageous for multi-unit projects as we can configure your setup into a single solution working for all properties and avoid the extra cost and space associated with separate system installations.

We facilitate effortless maintenance with unique crate designs that ensure easy access for cleaning and inspection. Stormbox II facilitates faster maintenance with an innovative wall design that enables high-pressure cleaning without damaging the foil casing.

Our smart level sensor allows you to monitor water levels inside the tank and take preventative measures to avoid overflows. You can also predict expected rainfall quantities with integrated weather data analysis via the Pipelife SmartHub.
