Swarm Aqua® D400kN Linear Drainage

Swarm Aqua® D400kN is the perfect solution for longevity on block paved, concrete or asphalt surface finishes where a D400kN loading is required. No removable tops and a solid iron top make Swarm Aqua® D400kN the product of choice for a wide range of sites.

With the same ductile iron top as Swarm Aqua® F900kN, this range has a reduced throat height, which can save time and money on site, or sit within height restriction requirements.

Why Choose Swarm Aqua® D400kN?

The Swarm Aqua® slot drain system is a revolutionary hybrid surface water drainage system that is taking the market by storm. The system offers cost savings, is quick and simple to install and has a superior aesthetic finish. Despite its light-weight design, it’s also ideal for use in areas of heavy loading traffic (up to D400kN).

 

Swarm Aqua® D400kN was designed to complement the heavy-duty capabilities of Swarm Aqua® F900kN by giving an option for loadings up to D400kN, while providing shorter and competitive product.

With a strong, durable ductile iron top section, this slot drain system combines steel side walls and HDPE Twinwall (plastic) conduit to make it the perfect solution for all external drainage applications.

What is a slot drain system?

A slot drain is a linear drain that is installed in the ground and is used to filter off groundwater. The main difference between a slot drain and other more traditional channel drainage systems is that a slot drain does not include any type of grating. Fundamentally, the slot drain is another type of trench drain or channel drain system.

The Swarm Aqua® drainage system is based upon the slot drain system and is manufactured to offer customers a number of key advantages.

Superior aesthetic finish

The narrow design of the slot drain means that less material is exposed than with other linear drainage systems, making it less obtrusive. Also, with a choice of cast iron, steel or stainless steel tops, you can achieve a far superior finish.

Simple to install

You don’t need to assemble Swarm Aqua® on site and because it has push-fit connections with a range of easy to use accessories, it is quicker and simpler to install than other drainage systems.
