ViaCon - Complex deep-depth, high-volume soakaway tank solution

As planning and construction on the “Junction” gateway at Newlands Park commercial development was getting underway, a few challenges presented themselves for the design of the soakaway tank. However, initial borehole testing showed that the ground didn’t have sufficient percolation at a standard seven-metre IL/CL. An additional percolation test revealed a need for a ten-metre IL/CL depth. This posed a unique design challenge, requiring deeper depth levels while also achieving the volume levels required for storage. By working on several different design variations to accommodate the depth and volume requirements, the ViaCon UK technical team developed a solution that both stores the required volume while also allowing water to permeate into the surrounding soil.
