Soakwells for the disposal of stormwater run off (roof water or surface water) need to be constructed such that the distance from all buildings and boundaries must be not less than the depth of the soakwell (measured from ground level).
All stormwater is required to be disposed of within the confines of the subject lot without detriment to any adjoining land.
With smaller lots, the location of soakwells needs to be considered carefully to obtain the necessary clearances. This will often mean locating them in the front or back yards of the property.
No Building Permit is required for the construction and installation of soakwells.
