Soakwells are underground tanks that gather rainwater and then allow it to seep gradually into the surrounding soil. What are some of the reasons for installing such a tank?
One of the environmental problems caused by stormwater is soil erosion. When the water is allowed to pour away down gutters and simply cascade over the soil wherever it lands, it can begin to wash the soil away. Over time this can lead to serious erosion of the soil, damaging the structure and the soil itself.
