The Rous County Council has confirmed plans to tap into groundwater on the Alstonville plateau days after Ballina Mayor Sharon Cadwallader confirmed support of a ‘water security’ project there.

Future water plans from the Rous County Council online show Stage One of a Future Water Project 2060 [FWS] for the region includes ‘Alstonville Groundwater’ via an Alstonville Water Treatment Plant [WTP].

Councillor Cadwallader also confirmed plans for the WTP days earlier to The Echo, saying the Rous County Council was working with Ballina Shire Council staff on submitting a proposal for the project.

‘The proposal will be coming to our commercial services meeting regarding that site, in order to build,’ Cr Cadwallader said last week.

The mayor was light on detail concerning funds for the project, saying she thought it ‘might have got some money somewhere along the along the way’.

‘But I think we’ve loan funded it mainly,’ Cr Cadwallader said, ‘I’d have to check into that for you’.

Cr Cadwallader, also Rous County Council Deputy Chair, said it was ‘possible’ a water treatment plant would be proposed, ‘because Rous County Council have started pumping from the Clarence Morton basin, because we know we’re going to run out of water by 2024’.

The mayor said the project was needed ‘before we can move forward on this Future Water Strategy 2060 with all options being on the table’.

Her comments came after a recent ordinary Ballina Shire Council meeting that featured repeated reference to eight hectares of council-owned land next to the Russellton Industrial Estate at Alstonville.

Other councillors, including Greens Cr Simon Chate and Independent Cr Jeff Johnson, had suggested the land could be opened up for private light industrial activity instead of including a bigger nearby parcel of State Significant Farmland in an official list of Strategic Urban Growth Areas for the shire.

But Cr Cadwallader had mentioned the possibility of the council-owned already being considered for a ‘water security project’.

Rous says connecting bore built in Wollongbar in January

Rous has been declaring a bore’s construction in nearby Wollongbar ‘a significant milestone’ as far back as February.

A project update from Rous that month declared an ‘important milestone with construction of a new groundwater supply bore at Converys Lane in Wollongbar Stage commencing in January’.

Rous said it was the Future Water Project’s ‘first piece of new water supply infrastructure’.

The council said it was ‘undertaking a rigorous process to develop’ the
new deep bore and meet ‘the requirements of the NSW Government’s Natural Resources Access Regulator’.

An accompanying flow chart showed construction had started.

Government yet to ‘sign off’ on Alstonville drilling plan

Earlier this week, Rous County Council Future Water Planning Manager Michael McKenzie told the ABC he hoped the government would ‘sign off’ on the proposed water-tapping project for the Alstonville project within the next six months.

Rous was still wanting to do more work and more consultation with state authorities aimed at approval for water drilling, Mr McKenzie said.

Stage One of the FWS online was identified as running from 2021 to 2025, with the Alstonville water project was to be the main focus for the first four years of the FWS.

Details showed it included developing a new groundwater treatment plant in the Alstonville/Wollongbar area and installing ‘associated infrastructure to transfer raw groundwater to the new treatment plant and treated water to the bulk water network’.

‘This new plant is needed to treat groundwater sourced from the Clarence Moreton Basin (Alstonville) groundwater source so it can be used as part of the fulltime regional drinking supply,’ Rous said.

Farmers’ water untouched but climate risks unclear

Water identified for the proposed project was separate from groundwater already used by farmers on the Alstonville plateau, Rous said.

‘This new bore is not the Alstonville Basalt Plateau Groundwater Source,’ the council said.

The ‘deeper Clarence Moreton Basin Groundwater Source’ was described at ‘around 220 metres below the ground’.

‘Adding this new groundwater source in the short term is expected to help secure our regional water supply from 2024/25,’ Rous said.

Preliminary planning works and other investigations related to stage two of the FWS were also said to be getting underway in 2022.

Stage two featured groundwater from Tyagarah in the Byron Shire.

But while reassurances were given on impacts to farming and existing eco-systems, climate risks were less certain.

‘Groundwater is less susceptible to the effects of drought conditions than surface water systems, such as creeks and dams,’ Rous said, but added ‘groundwater is not considered to be a rainfall or climate independent source of water’.

Rous said it was using the same approach as that used for surface water options when assessing impacts of climate change on long-term reliability.

‘This approach is recommended given the uncertainty surrounding the effect of climate change on groundwater resources,’ Rous said.

Rous said Stage three was due to start in 2030 and would depend on the outcome of ‘extensive investigations into the potential use of purified recycled water, desalination and more groundwater schemes as additional sources beyond 2040’.

$30 million-plus for St Helena water main repairs

Cr Cadwallader said elsewhere in the region the Rous County Council had started work on repairs to one of the main water supply connections at St Helena.

She said councillors were alternating meetings with workshops and field trips and had recently been to see the project site, with the work budgetd at around $35 million.

Cr Cadwallader said the St Helena pipe was more than seventy years and repairs had been on the Rous to-do list for some time.

The next Rous County Council meeting was due to happen on 14 December.

Support The Echo

Keeping the community together and the community voice loud and clear is what The Echo is about. More than ever we need your help to keep this voice alive and thriving in the community.

Like all businesses we are struggling to keep food on the table of all our local and hard working journalists, artists, sales, delivery and drudges who keep the news coming out to you both in the newspaper and online. If you can spare a few dollars a week – or maybe more – we would appreciate all the support you are able to give to keep the voice of independent, local journalism alive.


  1. So …..‘groundwater is not considered to be a rainfall or climate independent source of water’. ! ? Does that mean Rous thinks the fairies provide This volume of water to provide for the region ?
    I suppose that is as believable as the nonsense they have been sold on why the site at Dunoon has suddenly become unsuitable, after being bought and paid for by customers and situated in one of the highest rainfall areas in Australia.

  2. Amazing to all those pro dam/ toilet water to tap wingers. It turns out the aquifers are different. The lies during the local government elections have been shown to be lies! Now Sharon what’s this dam you dreamt up you suddenly proposed near the russelton industrial area? Maybe the mythical hospital will have water views?

  3. Oh dear Sharon, I thought that during your election campaign your “Independent” team went to great lengths to rubbish the use of the Alstonville plateau bores, claiming they would be pumped dry. What ever happened to the Dunoon Dam proposal that we thought we were getting, your “Independent” team ran hard on the need for a new dam, that’s what we voted for?

  4. Ratepayers better get used to paying even higher rates based on this article.

    The mayor doesn’t seem too interested. Incredible that she has no idea how the Alstonville Groundwater Scheme is to be funded. Does she even know how much the scheme will cost? The original reports said $26m, but that report had $20m in negative cost so the real cost was probably $50m+. That scheme didn’t include a water treatment plant (an extra $10m+ -> total cost$60m+) because Rous was going to use the existing Marom Ck WTP, but now they are going to build their own – although the mayor only said it was “possible” a WTP would be proposed – do they know anything about this project – they have been working on it for nearly ten years. And if it is only “possible” a WTP will be proposed, how are they going to treat the water?

    As to running out of water by 2024 – that is 13 months away so I don’t think that is going to happen – but maybe the Mayor thinks Rous will mismanage the system and Rous will go from full dams to empty dams by 2024.

    • Gary cheaper than building a dam that is on the same catchment as rocky creek. Anyway we might have to get use to the concept of using toilet water as the mayor carried on about last election due to these national independents lack of vision and not a farmer amongst them.

  5. It is certainly odd that, all of a sudden, Cr Cadwallader supports ground water as an option when she campaigned strongly for the LGA elections on a platform that completely rejected the use of groundwater.

    However, the use of groundwater is to be avoided if possible. Fortunately we have the solution to expensive infrastructure like dams and groundwater engineering. It is called water efficiencies but Rous and its beknighted, anti-science councillors have not even begun to discuss that yet in any depth.

    International evidence shows that comprehensive, well-planned and funded water efficiencies provide the fastest and cheapest way to provide the most water. One could add fairest and least destructive as well.

    Efficiencies could include solutions that with the stroke of a pen would provide more water, eg changing the levels of service from 5:10:10 back to 5:10:20. This would allow slightly more stringent water restrictions and would lay to rest the fear-mongering about “running out of water in 2024”. It would need some community consultation but that is what local water utilities are supposed to be good at.

    • That doesn’t fit the coalition mantra of building dams and pumping rivers dry while ignoring science, its even worse with this lot, National Party supporters that think land is for farming houses, it’s all this lot seem to want, and call is progressing.

    • Yes – Nanette is right….if you follow through her convoluted 1970s NIMBY thinking.
      Swingeing water restrictions are only a part of the solution for an increasing population on N/Rivers.
      So please don’t harvest” any more aquifiers, as it adversely affects the minimum levels our rivers and creeks.
      Control wasteful irrigation by all means, also follow Rous CC water conservation measures too – every bit helps.
      But in addition we must highten Rocky’s dam-wall and also plan for another dam at Dunoon as a back-up for certain future population increases.

  6. This story should have been released on 1st April, then we could laugh it off.
    Today will go down in history as the day they gave away the Alstonville Aquifer.
    Someone needs to tell them that water travels downhill, from the upper aquifer to the lower aquifer .
    In my 25 years of farming on the Plateau, we quite often ran out of water due to so called “safe pumping” of the lower aquifer.
    Today’s Politicians need to take a long hard look at this project, as once the aquifer is fractured, drained of resource by whatever means, this move will be the Death of Alstonville Aquifer. Save Alstonville Aquifer.
    Mike Hogan.
