About Wapro

Protection that works under pressure.

Based in Karlshamn, Sweden, Wapro develops patented solutions that protect people, properties and communities from flooding. Since 1989, its non-return valves, shut-off solutions and flow regulation products have been used in more than 75,000 professional installations worldwide — in stormwater, wastewater, industrial, residential and aquaculture systems.

As Wapro's partner, DND Construction Technicals (FZE) supplies these solutions for infrastructure and building projects — helping clients manage water safely, prevent backflow and keep critical systems working under pressure.

Flood Protection

WaStop® Inline Check Valve

WaStop stops water from flowing back through wastewater and stormwater pipes during heavy rain or when the network is overloaded.

  • Stops backflow through wastewater and stormwater pipes during heavy rain or network overload
  • Self-sealing design keeps out odours and pests
  • Responds automatically to pipe pressure — no electricity or manual operation needed
  • Installs horizontally or vertically in existing pipes, chambers or on walls — suits new builds and retrofits
  • Pulsating flow flushes debris through, reducing sediment build-up and keeping maintenance low
