Councils stormwater system consists of some “U-shaped” concrete lined drains and some grass lined drainage swales. This project was about redesigning our open stormwater drains to carry the minor flows through town and out of our high water table areas. To achieve this Council installed small v-drains in the base of some of our grass lined drainage swales to allow day-to-day trickle flows to be carried out of the town and therefore not contribute to our water table.
With heavy rains we see the entire drain fill with water and then in the days that follow, there is a steady flow of trickling water being carried in the bottom of the drain and out of town. The project is considered to be a success and Council will continue to source funding to complete the remaining network of grass lined drainage swales.
