The WaReg flow regulator has been designed to regulate stormwater during heavy rainfall, redirecting the excess flow to prevent flooding of our communities. We know that we will be seeing increased precipitation in the future. WaReg flow regulator is designed to be adaptable post-installation which helps future proof stormwater systems build today - but designed for tomorrow.
