About us

‘Klar. Water Solutions’ offers you, the B2B professional in water treatment, customized solutions and a breadth range of components & products for residential water treatment. Thanks to our years of experience and extensive knowledge, Klar’s team is perfectly placed to support you.

Klar. Water Solutions

More than 30 years ago, ‘Klar. Water Solutions’ was founded as ‘Aquina Wassertechnik’.

Since February 2016, it has been part of the internationally active ‘Pollet Water Group’. In 2023, ‘Aquina Wassertechnik’ became ‘Klar. Water Solutions’. With the new name, we also launch a new identity. ‘Klar’ stands for clarity, transparency and simplicity – attributes which we pursue with pleasure and as a top priority in the cooperation with our partners. The ‘Water Solutions’ that we develop, are set-up for our partners with know-how, commitment and always in dialogue. ‘Klar. Water Solutions’ is the B2B partner for dealers, distributors and specialist companies in water treatment. Our geographical focus is Germany and Austria. With our affiliation to the ‘Pollet Water Group’, we have access to a large portfolio of solutions, products and components as well as specialised know-how in all fields of water treatment.

Whether it is our own brand or specific water treatment solutions that are individually designed and manufactured for our partners, we find answers for the most diverse wishes and requirements. With the motto “We live partnership”, our entire team is at your side day after day with advice and action. 


A wide range of well-known brand manufacturers place their trust in ‘Pollet Water Group’ and thus in ‘Klar. Water solutions’. This applies to both standard and exclusive products.

Our Partners

Technical know-how

Thanks to our water treatment knowledge, we are true specialists. We use this specific knowhow in the design of products and in finding the right solution.

B2B is key!

We support you, our partners in water treatment. You have both the eyes and the ears on the end-market. We support you with customised solutions, our own brands such as “Vision Water” or standard stock products in order to serve our market quickly and appropriately.

Global and yet local

As a group, we are internationally active with offices in all major European countries. Therefore we are able to act flexible and across borders. Nevertheless, we think very internationally, we act very locally thanks to our partnerships and our ‘close to the customer’ philosophy.

Large, local storage capacities

Our local warehouse in Maintal near Frankfurt is well equipped with standard products as well as individual partner requirements. Should the product not be available in our local warehouse, we can deliver at short notice in most cases thanks to our connection to the central warehouse of our parent company in Belgium as well as all other warehouses of our sister companies.

Water Treatment XPRTS

We live and breathe ‘water’. It’s been in our DNA for more than 30 years. In 2015 we joined Pollet Water Group. That makes us part of a worldwide organisation with over 1450 water experts, 28 companies: from distribution to manufacturing and engineering.
