PWW sustainable wastewater technologies

Paul Wolschrijn (58) and Lex Valk (57) are experienced innovators / entrepreneurs with several patents on their name. They both have 30+ years of experience in the wastewater sector and in the field of innovation and design.

A ‘driver’ is the shared goal to grow several concepts and ideas into mature solutions that ‘make things better’ in a meaningful way. 

Starting as PureWaterWell in The Netherlands in 2015, PWW is since 2022 located in Malta.

“We combine vision, technical know how and business sense”

PWW contributes to a more sustainable world, that is our vision. 

We create and market water related processes and products, true solutions that have positive impact, this is our mission

We do this in a pragmatic way, honest, different from others, with clear vision and passion for ‘new and better’

We believe in small teams with little overhead that have the guts to fail first, change and still make things happen as the path to bring you innovation never is a straight line.



This year we market Xseppt, build systems, serve clients and grow PWW into a valuable company.

We further develop a clever product that optimises chemical dosing for flotation units and of course, our own Xseppt. 

We patent and raise the TRL of our new sustainable coagulant. The promise is that it boosts sustainability and performance of sewage treatment plants globally.

…and perhaps have you on board, to work together, making things just a bit better and having fun doing so!
