Why are there different water rates?

Water usage charges are billed per kilolitre, reflecting the actual amount of water you use. Every quarter, a fee is applied for your access to the water supply service, covering the period specified on your Water Account Notice, and is calculated based on the consumption shown by the meter(s) at your property. 

Residential Customers  

The water usage charge for residential customers is based on a two-step tariff, or tier, using the consumption recorded on the water meter(s).  

  • Tier 1: For water usage less than 1 Kilolitre (KL) per day  
  • Tier 2: For water usage greater than 1 KL per day  

Non-Residential Customers 

The water usage charge for non-residential customers is based on a single tariff, using the consumption recorded on the water meter(s). 

The rates for the 2025/26 financial year are: 

Residential Tier 1 - $3.66 per kilolitre 

Residential Tier 2 - $5.49 per kilolitre 

Non-Residential - $3.66 per kilolitre 

The rates for the 2024/25 financial year were: 

Residential Tier 1 - $3.55 per kilolitre 

Residential Tier 2 - $5.33 per kilolitre
