Summary: 
A Danish innovation company offers unique flap gates that can improve draining of water from heavy rain or cloudburst, while preventing the return of sea- or bay water, which normally would cause the water level to rise into the pipe system and cause flooding. The solution is based on innovative flap gates, which are mounted on the piping system that drains the water out of cities or fields. The flap gates are lightweight, yet strong and flexible enabling them to withstand extreme weather condit
Description: 
The company was founded in 2004 in Northern Denmark, originally manufacturing nozzles for cleaning sewer pipes and rain water pipes. In 2012, the company started developing a new type of flap gates for these pipes based on the company's previous experience within the field and new innovative ideas. At the time of writing, the company has provided solutions based on the unique flap gates for 19 Danish cities and towns, including multiple solutions for the capital region. As the solution has proved its worth and a European patent has been achieved, the company is now ready to address new markets. Heavy rainfall causes challenges to the water infrastructure and increases the risk of flooding. However, this new type of flap gates reduces the holding back of water and, consequently, flooding as the innovative lightweight design allows it to let out water more easily compared to traditional flap gates. The purpose of the flap gate is to open when the pressure from the water inside the pipe system exceeds a certain level, enabling the water to be drained out into the sea, flood or stream to avoid flooding. Furthermore, the flap gate has the purpose to prevent sea- or flood water to be pushed into the city area with the risk of flooding or pollution of drinking water reservoirs. Therefore, it closes when the water pressure from outside increases, preventing the water to be pushed back into the piping system or streams. The flap gate is produced from glass epoxy, a light weight material, which ensures a very easy opening, enabling more water to be drained out. The strength and flexibility of the glass epoxy prevents the flap from being damaged or bumped from wear and tear. Due to a patented design, the flap itself prevents the build-up of sand on storm water outfalls that usually troubles the draining of water from within the streams. The construction includes a small whole and a nozzle construction on the backside that flushes the sand and enables the flap to move and, literally, dig out the sand pile. They are currently co-operating closely with the Urban Water Research Group at Aalborg University, where researchers are finalizing the scientific formulas for the hydraulic principles and formulas behind the solution. As far as possible, the company employs local subcontractors, which enables flexibility and efficiency in regard to both development as well as production.
