Victorian water prices have increased from 1 July, with several water corporations outlining how the changes will affect household, renter and business customers.
The Essential Services Commission approved the maximum prices Victoria’s 18 water businesses can charge in 2026–27. The changes apply to services including water delivery, sewerage services and associated charges.
Earlier statewide figures showed typical owner-occupier bills rising by about $73 in Melbourne and $68 in regional Victoria. That represented increases of around seven per cent in Melbourne and five per cent in regional Victoria.
Recent updates from several water utilities show how statewide price outcomes are being felt in individual service areas.
Not every Victorian water corporation has issued a separate public update on its 2026–27 price changes.
Why are Victorian water prices changing?
Utilities have pointed to a similar set of pressures behind the new bills. Inflation remains a major driver.
Greater Western Water said its 2026–27 increases largely reflect the large Victorian desalinated water order of 150 billion litres and high inflation, measured by CPI.
Barwon Water said it is facing higher costs for the goods and services needed to deliver water and wastewater services. It is also investing in water security as its region experiences prolonged drought.
Central Highlands Water said its tariffs will increase by CPI plus 0.6 per cent or CPI plus one per cent, depending on the services provided. It said the average owner-occupier bill for customers receiving both water and wastewater services will rise by $64 this financial year. Tenants in its region will see an average increase of $20.10.
Coliban Water said most water and sewer access prices will increase by an average of 6.3 per cent. That includes a 2.5 per cent price adjustment endorsed by the ESC, plus inflation.

How much will customers pay?
The effect on customers differs across regions and customer types.
Coliban Water said the average household bill will rise by $103.49 a year, or $1.99 a week. Renters paying for usage only will pay an extra 65 cents each week, with the average yearly bill rising from $517.98 to $551.53. Rural Coliban Water customers will see charges increase by 3.7 per cent, below inflation but above last year’s 2.1 per cent rise.
Greater Western Water customers will see different increases depending on whether they live in its central or western region. A typical central region household using 150 kilolitres a year will see its average annual water and sewerage bill increase by $84, or eight per cent, including CPI. A typical western region household using the same amount of water will see its average annual bill increase by $66, or six per cent including CPI.
Greater Western Water said the difference reflects the pricing structures of the former City West Water and Western Water that existed before the corporation was formed. It said it is gradually aligning prices across its service area to avoid sudden changes to bills.
Barwon Water said average owner-occupier residential water bills will increase by 5.1 per cent, equal to about $4.99 a month. Renters will see a rise of about $3.55 a month. Business customers will see an average increase of about $8.08 a month.
Which utility has the lowest increase?
Gippsland Water said its bills will have the smallest increase across Victorian water corporations. From 1 July, a typical Gippsland Water customer bill will increase by 2.8 per cent. That is below the current inflation rate of 4.1 per cent. The utility said customer bills will remain below inflation for a ninth consecutive year.
Gippsland Water Managing Director Sarah Cumming said the organisation has absorbed some rising costs through financial management.
“We’ve absorbed some of the rising costs through prudent financial management, so customers aren’t carrying the full impact of increased costs out of our control, like the economic regional transition,” Cumming said. “We’ve developed and invested in our own unique approach to drive financial management in every decision we make.”
Cumming said Gippsland Water has achieved efficiencies through energy cost reductions, selective fleet electrification, chemical optimisation and asset renewal investment.
She said its commercial business operations also help avoid additional wastewater treatment costs.
How are utilities supporting customers?
Affordability has been a clear theme across the utility updates.
Coliban Water said its Coliban Assist program supports customers experiencing vulnerability. The program includes Plumber Assist, leak detection, concessions, bill smoothing and payment matching.
Managing Director Damian Wells said the utility is balancing infrastructure investment with affordability.
“We’re carefully balancing the need to invest in critical infrastructure with keeping bills as manageable as possible for our customers,” Wells said.
Greater Western Water said support options include flexible payment plans, payment extensions, concessions, support grants and referrals to financial counselling services.
Barwon Water said it offers payment plans, bill smoothing, payment extensions and programs such as Arrange and Save. It has increased customer support investment from $3.1 million to $4.89 million over five years. A further $2.5 million will support plumbing programs, rebates, grants and education to help customers save water and manage bills.
Central Highlands Water said confidential financial assistance is available for customers struggling with bills, including payment extensions and flexible payment plans.
What does this mean for water customers?
The latest utility updates show a sector trying to balance rising bills with long-term service reliability. Utilities are dealing with inflation, water security pressures, infrastructure costs and regulatory price settings.
Customers are seeing those pressures reflected in different ways depending on their region, service type, water use and local price path.
For customers under financial pressure, the message from utilities and the regulator is consistent: contact the water business early.
Essential Services Commission Chairperson and Commissioner Gerard Brody said customers have rights if they are struggling to pay water bills.
“Victorians have rights when it comes to paying water bills. If you are struggling to pay, please get in touch with your water provider. They must help you manage your bills, and provide a range of options, such as flexible payment plans and assistance with concessions or grant applications,” Brody said.
