Wastewater Outfall

What’s changed?

Our wastewater outfall pipe needs to be repaired and we are budgeting $2 million for this work.

We plan to build storage for wastewater at our treatment plant to allow for future shutdowns for repair and maintenance at a cost of $2 million.

The pipe runs from our treatment plant at Awatoto, travelling 1500 metres out to sea. We regularly check the pipe and in 2018, we found that wastewater was seeping from the gaskets at a fibreglass join section, around 700 metres offshore. The join section is one of a kind and needs a special and complex repair.

We’ve been working to find an effective method of repairing the pipe.

We’re setting aside $2 million to repair the pipe and $2 million to create storage for wastewater at our treatment plant to allow for shutdowns for maintenance and repairs.

Since discovering the leak, we have carried out thorough monitoring to check any potential environmental effects. The good news is that our monitoring isn’t currently showing any noticeable impacts.

The costs for the repair to the pipe and the new storage would be funded from reserves (savings account) so there is no effect on rates.

Our pipe needs protecting from damage. We have teamed up with Hastings District Council and PanPac to apply for protection of all of our pipelines under the Submarine Cables and Pipelines Protection Act 1996. This application would establish a protection zone over each of the three pipelines. For more information and to give any feedback on the application, go to - Submarine Pipeline Protection
