Wavin acquires Dutch start-up MetroPolder

Wavin has acquired Dutch start-up MetroPolder, against the backdrop of increasingly extreme weather events and long periods of drought that have been affecting the liveability of cities around the world. With the acquisition, Wavin is expected to incorporate MetroPolder’s knowledge to close the water cycle in cities and make cities “future-proof”.

MetroPolder has developed a technology to capture water on roofs and reuse it for cooling, irrigation and recycling. The blue-green roofs are equipped with a buffer system, an internet-connected valve and an online dashboard. The valves sensors and rain radars control the water level and discharge real-time. This smart connection enables dynamic water storage. The technology has been implemented in projects over several locations worldwide, including the Netherlands, Guatemala, France the UK and US.  

Friso Klapwijk, CEO of MetroPolder said: “Wavin sees rainwater as a resource, not a problem. That’s where we found each other. We want to make cities future-proof, by applying smart water management. Think of reusing rainwater for for cooling cities to combat heat stress. We are pleased and proud to be part of the Wavin family from now on.”

Maarten Roef, CEO of Wavin, said: “The green/blue roof solution of MetroPolder is a proven successful, international, application that puts Wavin as a company in an even better position to make cities more climate resilient. Supplemented with the knowledge and expertise of MetroPolder, we are convinced that we will succeed in getting more and more cities to look at the applications of water differently. Because the opportunities are plentiful.”
