WaReg protects rivers and livestock
During the construction of the E22 road, the Swedish Transport Agency was faced with a requirement from the Swedish Board of Agriculture that the flow of water from the road should not exceed the existing flow before the road was constructed. This was a challenge because the construction of the road would potentially increase the volume of water flowing into nearby fields, meadows and the Vesan River. This would not only cause flooding and erosion, but it could also lead to agricultural land becoming unusable, with consequences for both farmers and animals.
The solution
To solve this problem, the Swedish Transport Agency chose to use WaReg flow regulators, which are designed to maintain a precise and constant water flow, regardless of pressure increase. WaReg was able to meet the strict requirements for small flows, ensuring that the water flow from the road did not exceed existing levels. By controlling the flow of dirty water from the road, WaReg allows it to be directed to open ponds and sedimentation areas, where it can be treated and cleaned before being released back into the environment. This prevented dirty water from flooding the Vesan River and nearby fields, preserving agricultural land and ensuring that farmers could continue to grow their crops and graze their livestock. WaReg’s high efficiency and reliability ensured that the Swedish Transport Agency could meet its requirements for road construction, while protecting the environment and supporting sustainable land use practices.
