Building near a water main
Buildings are not permitted near or over our water infrastructure. Easements are detailed below.
You are not permitted to build within three metres of a public water main and this distance may increase where necessary to protect our main as stated in the table below. We must have unrestricted access to repair, maintain or renew the main as required.
If you propose to build closer to the water mains than the stated criteria you will be expected to pay for the water main to be diverted.
| Diameter of water main | Easement |
| <=150mm (6") | 6 metres (3 metres either side of the water main) |
| 151 mm to 600 mm (6" to 24") | 7 metres (3.5 metres either side of the water main) |
| >=601mm (>=24") | 9 metres (4.5 metres either side of the water main) |
Please note: these easements are from the outside barrel of the water main
