The spokesperson said discolouration issues were caused by elevated levels of manganese, a naturally occurring mineral. <\/p>\n
\u201cContractors carried out a weekly flushing programme to reduce the build-up of manganese in the system.<\/p>\n
\u201cThis should help prevent larger accumulations that can cause significant discolouration.<\/p>\n
\u201cThe water treatment facility for this supply does not include treatment for the removal of manganese, as it wasn\u2019t present in the supply at the time of construction.\u201d <\/p>\n
The spokesperson said council had first noticed higher levels of manganese in the source water after Cyclone Gabrielle, and they had continued to rise to a level that was now noticeable to residents. <\/p>\n
The spokesperson said the new reservoir would improve the resilience of the water supply at Whirinaki and help meet demand during peak use periods.<\/p>\n
The Haumoana and Te Awanga and Napier water supplies had all had similar issues in the past until a new source was established. <\/p>\n
The old reservoir was now offline and demolition was underway, with the new reservoir expected to be operational by mid-2026.<\/p>\n
The council was also looking at an even longer-term solution.<\/p>\n
This included a connection to Napier\u2019s municipal water supply or a new water source and treatment plan. <\/p>\n
The spokesperson said its preferred option was a connection to Napier\u2019s water supply.<\/p>\n
Modelling is underway using a recently developed water supply model to determine whether the Napier network can provide enough pressure and flow to service the Whirinaki and Esk Valley communities. <\/p>\n
The second option involves developing a new water source and drilling a new bore or bores to supply a new treatment plant outside the flood hazard zone, connected to the existing reticulation network. <\/p>\n
The council was working with a landowner and, subject to final agreements, planned to proceed with investigative drilling in March. <\/p>\n
Modelling is also underway to assess the impacts of supplying the network from this location. <\/p>\n
Funding for the project has been approved through council\u2019s Long Term Plan. <\/p>\n
Temporary water storage has been installed to ensure a continued water supply while the reservoir is being replaced. <\/p>\n
It is expected to be finished by mid-2026.<\/p>\n
Flood mitigation work by Hawke\u2019s Bay Regional Council was planned for March 3, which needed a temporary shutdown of part of the watermain. <\/p>\n
The work would likely cause temporary discolouration to the water and residents were advised to stock up on clean drinking water and avoid washing clothes on the day.<\/p>\n
