During construction recently, it was found that no staff from local power utility Te Aponga were on site while CCECC workers were trench digging while carrying out work in replacing the island's ring mains. Not having staff on site could cause power outages or serious injury, emphasised Schmidt.
A second work-stop order was issued due to the CCECC having too much trench open, adversely affecting traffic flows. According to project guidelines, the contractor cannot exceed a limit of 200 metres of open trench.

Despite what may be the best intentions of the project's various stakeholders, Batty said he has reason to believe that the required New Zealand and Australian standards as set out in the Te Mato Vai Master Plan are not being met - based on his assessment of the construction work undertaken thus far.
And taking into account those observations, he said the ring mains could have a shorter-than-expected life span, along with possible leaking at random joints due to poor welding.

The previous quality assurance process which was applied during the construction of the pipeline laid through the “Project City” project involved only testing for water pressure.…the laying of the pipeline for Te Mato Vai has undertaken a more stringent two stage testing process. The first stage being water pressure testing, to test for leaks in the pipes, the second test being peels tests to check the adhesiveness of the electro fusion welds that join the separate lengths of pipe.

There should be no confusion. The 1960 Ordinance deals with water, not with the ownership of the land where that water occurs. Cook Islands landowners have a constitutional right to be compensated for the use of their land. Any agency that thinks it is going to bulldoze those constitutional rights should think again. When these matters move to the High Court, that is where the question of the land itself will be dealt with.
- 12 Dec 2014 Declaration situation explained. Tamari’i Tutangata CIIC in Cook Islands News.
The second phase of Te Mato Vai is about to get under way … Phase two involves reconstruction of the intakes and the building of storage capacity and filtering facilities downstream from the intakes; and where necessary, the trunk mains that feed water into the ring mains will also be replaced. … The Rarotonga Waterworks Ordinance 1960 provides for the construction and maintenance of infrastructure on Rarotonga for the public supply of water. If procedures in the Ordinance are properly followed, the Government can enter onto private land to lay pipes and construct water tanks and other water infrastructure. This right of entry does not affect the land owner’s right to receive compensation for their land, including for any damage to the property as a result of the works undertaken.

- 12 Mar 2015: Better done right, says Brown
Many groups are angry at the government for not consulting with landowners or offering compensation for the use of their land. "Some land owners have been militant in their approach and their demands are selfish in nature because they are holding onto a public good," Brown said. …He hoped government would be able to fast-track these objections and that they could be settled out of court.

The relevant Standing Order is S/O 82. It requires that once tabled the petition would stand referred to a Select Committee to be appointed by Parliament.
Government of course was delighted to think that the ill-conceived and constitutionally questionable hasty dissolution of Parliament last April  meant that the whole annoying thing had been brilliantly despatched forever.
Government's frustration of due process with Te Mato Vai Petition and the continuing trench digging and pipe laying have not, as Government no doubt would like to think, rendered further pursuit, airing and investigation of the petitioners' pleas academic. There are many features to those petitioners' grievances which remain to be investigated.

"I think there will be a big uproar over the proposed chlorination of water in Rarotonga, because a lot of people are already opposed to it," Wichman says.

People have had their jobs threatened if they make a public stand, and this actually happened before the latest march against purse seining. All government workers were told they could participate so long as they were not recognisable as a government worker, in uniform and the like. The directive said they could, but the unwritten between the lines was felt by all who read it and decided they could not risk their job as they had mortgages to pay and stayed away.
Others were whispered to in the bank queue about what could happen if they signed the Te Mato Vai project petition. It was inferred that you might somehow find yourself unemployed.

The water may well fall free from the heavens, but gathering it up and delivering it to your home or workplace and taps, costs money. And each year we currently have about 1000 people getting sufficiently sick from water borne diseases that they see a doctor or go to the hospital. The young and the old are particularly vulnerable – so there is a cost there too.

landowners. These people were soon
recognised their presence was to
persuade landowners to support
government and their views were robustly challenged.
Landowners are sceptical
about this government’s

A number of their issues raised have been addressed.”

Not every person infected from contaminated water falls ill, but young children, the elderly and unwell are more vulnerable because they have a lower resistance to disease."
The Te Mato Vai project management unit has recommended chlorination as the most suitable disinfection option for Rarotonga. "Our disinfection options assessment included safety, complexity, reliability, capital cost, and ongoing operational and maintenance costs. Based on this assessment, chlorination is the safest, most cost-effective and reliable disinfection system for Rarotonga."
"Even if the government chooses an alternative disinfection method to chlorine (for example UV) chlorine will still be added to the water to disinfect the pipes. This is necessary to ensure the water network remains safe from contamination. Chlorine is the only method that can achieve this."

The Te Mato Vai Project Management Unit (PMU) has ordered a 'coagulant' chemical to enable a key step in the new four-step water treatment process that will provide reliably safe water to Rarotonga's communities. Coagulant plays a key role in cleaning the water but is different from disinfection, which kills bacteria and viruses….If a coagulant step was not used, the AVG filters would likely get blocked, and the filters may not operate at all during storms. Importantly, the water treatment would not achieve 'potable' quality, leading to continued health risks.

When the last section of our public water supply pipeline was commissioned in the early 1960s, many people became sick after drinking water from the new reticulated system, and this contributed to three deaths.
In 1964, the completed pipeline section was commissioned. Within a few days, many people in the above area became sickened after drinking water conveyed in the new pipeline. Many were admitted in to hospital and this disease outbreak contributed to the loss of three lives.
A subsequent inquiry identified the cause of the disease outbreak to be the failure to properly 'flush and disinfect' the new pipeline with chlorine prior to releasing water to consumers.

- 4 Jan 2020: The water debate continues. Te Ipukarea Society in Cook Islands News
Flocculation is a process of settling out particulate matter, for example dirt, from the water. Given that PACl is a chemical that produces a potentially toxic sludge as a byproduct of the flocculation process, this trial needed to be properly assessed for environmental impacts before it was approved.
Another purpose of an EIA is to look at alternatives that may have a lesser negative impact. Therefore, from an environmental perspective, the logical thing to do to reduce dirt getting into the water is to first trial alternatives which provide a lower level of risk to our freshwater ecology.

Information gathered will contribute to the Environmental Impact Assessment report commissioned by Rarotonga's water supplier, To Tatou Vai… Leading the study are aquatic ecologists Dr Natalie Clark and Lauren Pratt, who are employed by GHD New Zealand, which is engaged by the Cook Islands Government to deliver and manage Rarotonga's new water facilities.
- 31 Jan 2020: Cook Islands water system EIA 'too narrow' Te Ipukarea Society / Radio New Zealand News.
"After talking to the consultants [Tonkin and Taylor] this EIA is only looking at the use of polyaluminium chloride…it's not looking at chlorination and they may as well do the whole thing all at once…The EIA is not really looking at alternatives, it's merely looking at the impacts of the PACl and how these may be reduced or mitigated on the assumption that PACl will be used."
- 3 Feb 2020: Cooks water system chief calls Rarotonga water 'unsafe' RNZ News.
Brent Manning, who is the chief executive of the company managing the system, To Tatou Vai, said the decision was not for his company to make but he said some form of disinfection was absolutely vital. "There are many, many bacteria in this water supply here. In fact, I would go as far as to suggest that if this was in any other developed nation the water supply here would be condemned, because it is, based on the testing and results we have seen todate, it's completely unsafe,… he said.
- 9 Feb 2020: What happens when we commission Te Mato Vai? Release, Te Mato Vai PMU.
How will you monitor the impact of PACl use on the streams?
During the trials, we'll do a mix of tests within the water treatment plant and in the streams. This includes testing for dissolved aluminium in water. These tests will be at regular intervals, and each time we need to adjust the amount of PACL we're using.
Have PACl trials started?
As at 5 February 2020, PACl trials have not yet started. We will give landowners at least 48 hours notice before beginning the trials.
Why are you trialling PACl at all 10 intakes?
1. Trialling PACl at all sites will enable us to capture information specific to each intake site;
2. Treatment, including PACl use, needs to be applied at a whole of network level to achieve its benefits - improved public water supply quality; and
3. We are able to manage and monitor the trials to mitigate any potential environmental impact.
- 18 Feb 2020: Why only collecting stream water when the water is running 'clear' is not an option Release, Te Mato Vai PMU.
The option to bypass the intake during wet weather events is impractical and detrimental.
1. PACl dosing is still required for treating 'clear' water flows.
2. Collecting water when the streams are in high flow (generally during heavy rain) will help prevent public water supply shortages.
3. An effective bypass system would most likely need a permanent power supply at each intake site.

[To Tatou Vai CEO] Manning said the initial work was lawful. "This has been agreed with landowners through a consultative process, noting however that there is some opposition to the use of water treatment chemicals, but that doesn't necessarily make it unlawful.
The Tonkin & Taylor assessment, he said, was of the by-products of the coagulation process. Standard controls would be put in place for these, as was done worldwide. "Those by-products will take time to accumulate and therefore won't be required to be removed straight away."
He said data would be gained from the coagulation trial, to help inform the environmental impact assessment and related controls.

- 21 April 2020: How does polyaluminium chloride (PACl) work. Te Mato Vai PMU.
We need to use PACl in Rarotonga because stream water contains high levels of contaminants - everything from bird poo to leaves and soil. This is true for water taken from streams, rivers or lakes around the world, not just in Rarotonga. Even stream water that looks clear still contains harmful protozoa and bacteria too small for people to see.

The Government claims the trial is necessary to inform the environmental impact assessment. This claim is not supported by the GHD technical documentation, the Court-expert assessment, or the opinion of the consultancy firm preparing the To Tatou Vai environmental impact assessment submission. The Government’s claim requiring a trial is necessary, is a fiction.

- 4 July 2020: Two strikes but not out for petition. Katrina Tanirau, Cook Islands News.
Parliament’s Speaker Niki Rattle has ruled the Anti-Chemical Treatment of the Water Supply of Rarotonga petition out of order as Parliament does not have power to issue an injunction against treating the water with chemicals.
The prayer does not ask Parliament to “issue an injunction”, Flanagan said. Parliament is not the Court. “For a person to obtain an injunction order they must have a legal right that has been violated, petitioners have no legal right for the Court to uphold. The prayer is not a private application seeking a Court order. A prayer is a public request presented to Parliament for consideration by a select committee.”

Landowner Tere Carr said the intake landowners and people of Rarotonga should be very concerned about the Bill “which is robbing landowners of their right and tika’anga to our water”. Carr claims the government intends to take these rights through legislation “so that they don’t have to deal with landowners anymore. A tribe without water rights are nothing … the landowners agreed for free water for our people in lieu of compensation.

We will be following industry practice and guidelines to ensure PACl is used safely and effectively.
Is sludge safe? Well documented water treatment process science tells us that the PACl sludge is in many respects like a soil, and can be reused or disposed of in a number of ways without damaging the environment. However, like any waste product, PACl sludge must be managed responsibly.
How much sludge will the Te Mato Vai system produce? We can’t accurately predict how much sludge the Te Mato Vai system will produce because it will depend on weather, its effect on stream flows, and the unique conditions of each intake site. For example, heavy rainfall that disturbs the soil and carries more sediment into the stream will result in more PACl needed to remove the contaminants in the water and more sludge produced. This is one of the reasons for the PACl trials — the trials will help us understand how much PACl to use at each site, how much sludge will be produced and the sludge consistency.

Why didn’t this government first obtain an EIA? Everyone seems to be avoiding that question and ducking for cover.”

Rarotonga’s geography, ecology, and weather are posing unique challenges. “It’s very different here. Water gets dirty very fast, but it cleans up fast.” Developing water treatment systems is never an easy process, says Free, and getting to this stage has been a lengthy process. “They always are, but this one, probably a little longer than most.

The Cook Islands Economic Strategy 2030 estimates that households in the lowest quintile are only able to save $1000 a year after expenses. A water tariff of $80 per month guts that down to $40. Add to that the increase in the cost of food when growers are levied for water usage. How much for a watermelon when growers have to pay for water?… Given the current economic climate, this is not a time to burden, it is a time to rebuild. It is prudent that To Tatou Vai become a government agency, a rebranded ICI Water Division.

- 11 Jan 2021 OPINION: It takes courage to disagree with the government.
All the children were under the age of 10. Other young mums walked with demonstrators, leading their young ones by the hand. The young mums had joined a public demonstration in our main township against the adding of chemicals to the Rarotonga water supply; they also objected to the To Tatou Vai Bill.
