Rain and storm water management

Alleviate sewer systems, avoid enlarging sewers, prevent flooding, reduce discharges – there is a lot to be said for a safe, sustainable and economical stormwater management system.

It seems that nature is becoming more and more extreme. Long dry spells and heavy rainfall occur increasingly more frequently. For a carefree life under these circumstances, we need a sense of security.

Protect construction projects from flood damage in the long term.Invest in safe stormwater management. This puts everyone involved at ease: investors, local authorities and citizens alike.
Our RAUSIKKO modular system gives you everything you need.

Systematic rainwater management with all-round service

RAUSIKKO Solution includes solutions for all areas of stormwater management: from collection and treatment to percolation and drainage. And it doesn’t stop there. We’ll support you in all phases of planning and, of course, also during implementation.

Stormwater infiltration

On-site infiltration. Decentralised stormwater management reduces the burden on the sewerage system and helps groundwater levels to recover. We offer solutions for areas with harmless, tolerable and non-tolerable contamination.

Rainwater retention

Store stormwater and control drainage – the on-site solution when seepage is not an option. The advantage: reducing the burden on existing sewage networks – without having an expensive extension to the sewage network.

Five reasons why our system solutions for reliable rainwater management will also benefit you:

Innovative and forward-looking

We are always leading the way with our products, demonstrating new possibilities that comprehensively future-proof your rainwater management system. We can now equip rainwater systems with digital sensors, which creates a whole new level of transparency in real time.

Tailored to your needs

All components can be easily combined within the system. This allows us to offer each customer a completely individual system in which everything fits together cohesively.

Durable and reliable

Thanks to the many innovations and high quality standards, RAUSIKKO products remain functional over the long term, with relatively low maintenance requirements.

Safe and resilient

RAUSIKKO solutions meet the highest standards, both in terms of load capacity and product safety. Even under extreme conditions, installation can be performed in compliance with all requirements.

Easy to install

Installation of RAUSIKKO Box products is as simple and time-saving as it can be. Thanks to the lightweight polymer design, everything can be set up by a single person without heavy equipment. With the push-fit sockets on each box, the gravel trench has maximum stability without connecting clips. And as for the connection of chambers, you can cut everything to size as needed.

Simple assembly

RAUSIKKO adapts to every application: whether it’s stormwater seepage, retention or storage. It is suitable for box and ditch box gravel trenches. Ideal for use near residential and commercial buildings, in logistics areas and car parks, near roads and in development areas. And RAUSIKKO is extremely quick to install – without connecting clips. Our built-in push-fit sockets provide support and stability.
