How customers rate their water business
We survey 5,800 water customers every 12 months across 15 state-owned urban and regional water corporations on four key areas: value for money, reputation in the community, level of trust and overall satisfaction.
Customers rated each area out of 10, and we update these results each quarter to show the previous twelve months of survey results.

How we compiled these survey results
We engaged an external company to help us develop a survey that will be used to identify trends in what Victorian water customers think of their water providers.
We completed a 12-month trial to check that our survey questions were successfully helping us find out more about what Victorians think of their water provider. The trial confirmed the questions asked would elicit results that could be tracked over a long period of time and gave the businesses room to improve.
We use automated robocalls to survey around 1,450 Victorian water customers four times over the year (5,800 customers in total). We surveyed 100 customers from each urban and regional water corporation (except for the two smallest water corporations, Westernport Water and South Gippsland, where we surveyed 25 customers).
We did not survey the same customers in consecutive surveys, which allowed us to survey a range of customers. We also surveyed people at different times during the quarter to make sure results weren't influenced by things like billing.
We're confident our results reflect customer sentiment
Based on the number of people surveyed over a 12 month period, we are highly confident the results we've collected reflect the entire customer base of water providers.
Our survey results reflect a twelve month 'rolling average'
The results we publish for each corporation is known as a ‘12 month rolling average’. This is based on the average of all four quarterly survey results in a 12 month period.
We do not publish quarterly results because 12 month rolling average results are a better indication of overall customer sentiment. This may mean that changes made by a water corporation will take longer than one survey period to show in the results.
Our water pricing framework encourages better consumer outcomes
In 2016 we released a new pricing approach called PREMO. One of the aims of PREMO is to shift water corporations’ focus to their customers’ priorities.
In 2018, we completed a price review for 16 of the 19 water corporations. We reviewed 15 of these water corporations under the PREMO framework.
As the Victorian economic regulator for water, we monitor the performance of water corporations against their pricing proposal commitments. View more on how we regulate the water sector.
You may receive a phone call about this survey
We aim to reach a wide variety of customers through our survey, which we run every quarter. You may receive a phone call asking questions about how satisfied you are with your water business. The answers to these questions provide us with important information, directly from customers, about their level of satisfaction. The survey is based on a short script and runs for roughly two minutes.
