Allowable planting on water and sewer easements
If you have an easement on your property you can use the area, but you must ensure we can still access the infrastructure, including underground pipes and cables.
It's important you carefully consider your landscaping plans as plant roots can damage sewer pipes, obstruct the flow and eventually cause blockage. It can also let stormwater into pipes. Root damage can be reduced by not planting species likely to cause problems,and planting trees far away from pipes.
Before planting a tree, you should first find out where the water and sewer pipes are located so that you can stay clear of them.

The Northern Territory boasts a plethora of native plant species that have vast ornamental potential. The following is a list of suitable species recommended by Greening Australia NT for urban planting in the Top End. These trees are also suitable for planting close to sewer or water easements.
Native plants are adapted to the Australian climate, requiring less water, less fertiliser and less fuss,so you will have more time to sit back and simply enjoy your garden. By planting native flowering plants you can also attract (and help to preserve) some of the unique Australian wildlife, including birds, frogs,lizards, butterflies and native bees. These creatures will help to control insect pests in your garden and pollinate your flowers.

Non-native plants and un-listed natives are not allowable within Power and Water easements.
When planting trees or shrubs in a sewer or water easement ensure you allow one (1) metre plant-free zone over the centre line allowing Power and Water free access to the water or sewer main line for repairs and maintenance.
This will result in less damage to pipes and less damage to the plants when Power and Water has to repair the pipes.
