Water Supply

Napier's Long Term Plan consultation is now closed. 

Thank you for taking the time to make a submission. Your feedback is really important to us. All feedback will be considered before Council adopts the Long Term Plan on 30 June 2021. 

Water Supply Option 1We propose this option because we have heard loud and clear that you see clean and clear water as a top priority - and we agree. We know that our network is outdated and will struggle to keep up with new and changing standards for drinking water supply, and we also know that modernising our system to achieve better security could take a long time. There is no time like now to start the work – the sooner we begin, the sooner we can all benefit.

Key projects that will modernise our network:
  • Two main bore fields with treatment plants that feed into our reservoirs
  • Replace Enfield reservoir (Mataruahou – Napier Hill) and related pipes
  • Create mini networks within our main network
This option:
  • Means we will meet national drinking water standards within five years
  • Has a total budget of $74 million capital over the next 10 years – $36 million would be spent within the first four years
  • Higher loan repayments starting in 2022/23
  • Higher operating costs over the plan

Water Supply Option 2This option delivers the same outcomes as our proposed option but the work is spread over a longer time period. The main positive of this option is that it reduces the rates increase for the next three years by 0.12%. The downside is that the benefits of a modern, more secure network will take longer to take effect.

This option:
  • Means we will meet the national drinking water standards within 10 years (this may not be supported by the new water regulator)
  • Has the same total budget of $77 million ($74 million plus inflation as our proposed option, but reduces the amount we had planned to spend in the first four years to $22 million (most of the spending starts from 2025)
  • Lower loan repayments over the plan
  • Lower operating costs over the plan

Clean, clear water supply is a must for Napier. But we need to overhaul and modernise our system to achieve it.

After spending time assessing our current system, looking at what needs replacing, and how best to monitor and secure our system – it is clear there is a lot to do.

Some of our bores either need replacing now, or will need replacing soon. We also need to reduce the manganese levels in the water that flows into our homes and businesses. The mixing of manganese and chlorine is responsible for the dirty water many of us have been experiencing.

To lower the levels and achieve clean water, we need to build new, modern treatment plants or find new water bores with lower manganese.

We also need to break up our network into mini networks so that if we face issues in one part of the city, for example a leak, it can be dealt with without it affecting the rest of Napier. It also means we can monitor our water systems better.

New reservoirs are needed. We’ve bought land on Mataruahou (Napier Hill) to establish up to three new reservoirs.

All of this means our network can supply cleaner water that is more secure.

We now have two options: the work can be done sooner or the work can be done later. We want to do the work sooner so that some of the issues like dirty water can be dealt with earlier.

Another reason we’d like to act quickly is because the Government has indicated that new drinking water supply standards are on the way as early as this year. A draft of the standards has only just been made available and we need to see how our current plan will need to be adjusted to meet them. It is possible that we’ll need to action some temporary fixes to make sure our system meets the standards by the due date.

To take a look at the draft drinking water standards please see supporting documents.
