No.1 Drain is a 480-metre long drain located in the Shirley Links Golf Course. The Drain suffered extensive earthquake damage. Further failure could result in an increased flood risk and repair is needed to ensure the drain keeps functioning.
The Council today agreed to repair work on No 1.Drain. The agreed work programme will see the western half of No.1 Drain repaired through ‘naturalisation’, where the concrete channel will be replaced with natural earth banks and planted. Spot repairs will be done on the eastern half of the drain.
This will bring improved capacity to the waterway, and improve its ecological health with the formation of new habitats and shading of the waterway. The $1.5M work programme will be funded from the Land Drainage Recovery Programme, with construction looking to start early next year.
The Council also agreed to include design for stormwater quality treatment as part of the detailed design work for No 1. Drain.
