Waiapu River flood control

Installing dolosses in Waiapu RiverSignificant improvements have already been made in protecting Ruatoria township from the erosion caused by the Waiapu River.

What we plan to do

Large concrete groynes installed to divert the Waiapu River away from the Ruatoria township are working well. The porous groynes are slowly diverting the water flow towards the middle of the river and away from the badly-eroded right bank.

Stage two of the project will involve installing more groynes upriver. This is planned for 2012/13 and will cost $200,000. If fully effective, stage three – which is planned to start in 2013/14 and cost $415,000 - will not be needed.
