Solution

Flood protection

Protect properties, infrastructure and water and wastewater systems against backflow and flooding caused by high water levels and heavy rainfall.

A flood can quickly have serious consequences

Heavy rainfall, high water levels and overloaded pipe networks can cause backflow in stormwater and wastewater systems. When water can no longer drain away or begins to flow back through the system, the risk of flooding and damage to properties and infrastructure increases.

Effective flood protection prevents backflow while allowing water to flow in the intended direction under normal conditions. Our solutions protect vulnerable parts of stormwater and wastewater systems – and ultimately the people, properties and communities affected when these systems fail to function as intended. The solutions can be used in both new and existing installations.

    The largest WaStop Non-Return Valve ever installed in Finland

    With the consulting engineering office contacting Wapro’s business partner in Finland, Ulefos Oy to find a solution, a teams meeting was setup with Wapro to discuss possible solutions. In the end, a customized WaStop DN1600 with bell-bolt installation was decided to be the best option for the application. With the bell-bolt option, the contractor could install WaStop above ground in the new DN1600 stainless-steel pipe instead of having to conduct the installation process of the valve at the outfall-site.

    The DN1600 stainless steel pipe with the WaStop pre-installed was then lowered in place to connect to the upstream inspection chamber with ease.

    The WaStop will ensure an effective evacuation of the stormwater with the lowest head loss amongst inline-check valves on the market and will help protect this beautiful area of Helsinki from flooding in the future.
