Heavy rains had caused the two lakes to overflow onto the park and water was entering the houses alongside the lake due to the overspill drain being blocked. CSA was contacted to assist in unblocking the drains to get the lakes water levels down to its original state so that the overspill drains would flow
CSA were engaged to unblocking a large SWD pipe in early June 2019. The Open channel drain had not been maintained for many years causing the 900mm diameter SWD pipe under the road to silt up and become 90% blocked. The drain could not flow to its full capacity causing flooding upstream of this pipe.
