Water pricing
• Water pricing is made up of two components:
Service charge – relating to infrastructure
Volumetric charge – actual water used
• WPW is considering options for pricing that…
Are fair to all customers
– Permanent
– Non permanent
Consider affordability issues
Support customer awareness of water usage
Recovers enough to run the business
In Confidence
Water pricing - issues
• Customer base
60% non permanent residents
40% permanent residents
• Pipes and pumps sized for peak
Underutilised for majority or year
• Need to recover full cost plus future cost
In Confidence
Water pricing - options
Option 0 – Status quo Service charge with volumetric charge
Option 1 - Step tariff structure with affordable first tariff block
• This system would result in high water users paying a higher
premium for water
• This structure would only apply to domestic customers, not
commercial who are often higher water users
Option 2 - Lower the service charge raise volumetric charges
• Applies to domestic and commercial/ rural customers
• Overseas experience is that low-income households are
much more likely to have below average water consumption

Continue to use our current reservoir (Candowie
Reservoir) with groundwater and the Bass River
2.
Extend Candowie Reservoir – in the short term
3.
Extend Candowie Reservoir – in the long term
4.

•
Option 1 – continue to use Candowie reservoir with
groundwater and the Bass River
Involves obtaining…
1.6 Gl from aquifer
1 Gl from Bass River
Environmental impact
Reliability of bore uncertain
Relies on rainfall
In Confidence
Water supply security - options
Option 2 – Option 1 plus extend Candowie Reservoir
In the short term this would yield an additional 500Ml
Option 3 – extend Candowie Reservoir
Double the Reservoir capacity
Raise the reservoir wall
Cost: $15 Million
Additional land would need to be purchased
10% increase in accounts
In Confidence
Water supply security
Option 4 – Connect to Melbourne
2200 million litres per year
Pipeline and pumping
Relies on water availability
Slow recovery of Melb system
Large scale desalinisation possible
