“2% of the Population, 38% of the Assets”: How TasWater Is Unpicking a Century of Fragmentation

Exec Exchange – Episode highlight with George Theo, Chief Executive, TasWater (Australia)

What happens when you inherit a hundred years of local decisions in a state-wide water utility?

In Tasmania, the answer looks like this:

  • 2% of Australia’s population
  • 38% of the treatment plants operated by the country’s 16 largest utilities
  • 110 sewage treatment plants serving just 470,000 people
  • And, until very recently, 24+ towns with permanent “boil water” or “do not consume” notices

In this episode of The Exec Exchange, Dr. Piers Clark talks to George Theo, Chief Executive of TasWater, about what it really takes to turn that kind of legacy into a fit-for-purpose, modern utility – without breaking either the balance sheet or the communities it serves.

George has been here before. As former CEO of Unitywater in Queensland – itself formed from a merger of six council utilities – he knows the mechanics and politics of consolidation. But as he puts it, Tasmania is another level:

“You can look at it two ways: either you have too many assets for the customers you serve, or you don’t have enough customers for the assets that you have.”

From 29 Council Businesses to One State Utility

TasWater was formed in 2013 as an amalgamation of 29 council water businesses. On paper, it’s straightforward:

  • Vertically integrated – from catchments to tap to sewer outfall
  • State-based utility covering 68,000 km²
  • 470,000 customers, plus around 1.3 million tourists a year
  • Owned by 30 shareholders: 29 councils + the State Government of Tasmania

The governance model is deliberately de-politicised:

  • A skills-based, independent board of seven directors
  • Councils receive dividends in line with the value of the assets they contributed
  • The state government is a shareholder but takes no dividend

That structure matters. It’s what allows TasWater to:

  • Move capital across the state,
  • Tackle problems that individual councils simply couldn’t fund, and
  • Take a long-term, state-wide view on consolidation and compliance.

Fixing the Drinking Water First

When TasWater was created, Tasmania had an uncomfortable statistic:

24 towns (which ultimately became 28) were on either permanent boil water or do not consume notices.

Small councils with thin tax bases simply couldn’t afford the upgrades. TasWater’s first mandate was brutally clear: fix safe drinking water.

In George’s words:

  • TasWater “had to build 30 treatment plants in six years”
  • It used its consolidated balance sheet to invest in communities that had been stuck for decades
  • The last boil water notice was lifted in 2020

That early win is more than a PR line; it’s the platform on which TasWater must now argue for its next wave of investment. George is adamant that the organisation – and its regulators – must not forget how recent that milestone is as they move into the next economic period.

The Real Beast: Sewage, Compliance and Over-Asseted Networks

If the first chapter was drinking water, the second is sewage – and it’s a lot messier.

TasWater operates:

  • 110 sewage treatment plants for 470,000 people
  • Of those regulated by the Environment Protection Agency, ~25% are non-compliant with effluent standards

In Hobart, depending on how you count:

  • There are 14–19 sewage treatment plants serving ~200,000 people

In Launceston:

  • Seven sewage plants are planned to be rationalised down to one over a 10–12 year horizon, serving 70,000–90,000 people

For George, the long-term target is clear:

“We think the long-term solution is going to be anywhere between probably 60 and 70 plants, but that’s going to come over decades.”

So how do you go from 110 to 60–70 without stranding assets or hitting customers with unaffordable bills?

Rationalisation by Stealth (and by End-of-Life)

One of the most useful pieces of practical insight in this episode is how TasWater is structuring its rationalisation:

  1. No big-bang write-offs
    • Instead of upgrading every non-compliant small plant, TasWater asks:
      • “Can we decommission this plant and pump to a neighbouring, larger facility instead?”
    • Investment is redirected from upgrade to decommission-and-transfer.
  2. Aligning with end-of-life
    • Plants are targeted when major capital would be due anyway.
    • That limits “wasted” investment and eases regulatory conversations about asset write-downs.
  3. Building scale where it matters
    • Fewer, larger plants (e.g. in Launceston and Hobart) enable:
      • More efficient operations
      • Higher-quality treatment
      • Viable recycled water and circular economy opportunities at meaningful scale
  4. Working with councils, not around them
    • TasWater is actively collaborating with councils to:
      • Put more growth onto existing, under-used assets
      • Plan transitions in a way that supports regional development rather than undermining it

It’s a blend of engineering logic and political realism. As George notes:

“There’s a bit of science in all of this, but there’s a bit of art involved as well in how you arrive at the final decision.”

Regulatory Cycles: 12 Years or 30 Years?

TasWater is currently preparing its next pricing submission, due in mid-2025. The stakes are high.

The question is not if legacy issues will be fixed – it’s how fast:

  • With the right regulatory and pricing outcome, George believes TasWater can resolve the major sewage and compliance legacy issues over perhaps three regulatory periods (say 12–15 years).
  • With a weaker settlement, that timeline could easily stretch to 24–30 years.

And that’s not just a technical debate. It becomes a test of:

  • Community expectations around river and coastal health
  • Political appetite for bill increases
  • Regulatory willingness to back a long-term rationalisation strategy rather than piecemeal patching

George is very clear on the balance he’s trying to strike:

  • Protect vulnerable customers – TasWater will continue to support families and individuals who struggle to pay
  • Confront the legacy – decades-old issues in sewage networks and treatment must be addressed, not kicked further down the road

Culture: “We’re Not Going to Be Victims of What We’ve Inherited”

You don’t rationalise half your treatment plants, lift dozens of boil water notices, and confront non-compliance across a state by accident. You need a team that’s up for a fight that may last most of their careers.

George has reshaped TasWater’s leadership:

  • 5 out of 7 executive team members are new
  • Significant renewal at senior leadership levels
  • A strongly articulated corporate strategy endorsed by the board

The attitude he’s trying to cultivate is strikingly simple:

“We’re not going to be the victims of what we’ve inherited. We’re actually going to fix these things and we’re going to have a bold ambition to address them in a timely manner. It’s for someone else to slow us down. We’re not going to slow ourselves down.”

For other utility leaders, that line alone is worth the 15 minutes.

A Working-Class Ethic for a State-Wide Utility

The episode closes on a personal note. Asked what he owes his parents, George doesn’t talk about networks or strategy. He talks about work.

  • He comes from a working-class factory family.
  • The lessons were simple:
    • “Earn your dollar.”
    • “Doesn’t matter what you do, do it as well as you can.”

In a state where 2% of the population is carrying 38% of the assets, it’s a useful philosophy:
do the work properly, even when it’s hard, even when it takes decades.

Why This Episode Matters for Water Leaders

If you’re grappling with:

  • Highly fragmented legacy assets
  • Multiple owners or councils
  • Non-compliance scattered across small plants
  • The politics of rationalisation and write-downs
  • Or preparing your own long-term business plan under regulatory scrutiny

…TasWater is essentially your future, just with more wilderness and better scenery.

In “2% of the population, 38% of the assets”, The Exec Exchange gives you a candid, operationally grounded look at how one utility is turning structural disadvantage into a structured, long-term transformation program.
