Leak detection tool

Empowering customers to self-detect and resolve water usage issues to reduce customer support calls.

Problem

Customers don’t notice water leaks until their quarterly bill, leading to delayed detection and financial strain

There are no timely and proactive notification system in place for customers to detect unknown leaks. Customers often discover these issues only after receiving a high bill, resulting in bill shock. This surprise often prompts them to contact Yarra to understand the cause, increasing call support volumes.

Understanding internal processes and its impact on customer experience

I set out to understand how internal processes shaped the customer experience, especially around high bills and leaks, so we could design a solution that worked for both the business and its customers.


My focus was on understanding customers' awareness of leaks, their reactions to bill shock, and their preferred support methods. From internal teams, I aimed to uncover the business processes impacting leak resolutions, while insights from frontline staff provided a firsthand look at real customer interactions around high bill inquiries.

With insights from discovery, I mapped out the current state of the customer experience against business processes to understand where they might be getting stuck in the journey

After mapping the customer journey, clear opportunities emerged to improve the first two phases, particularly when customers contact us after receiving a high bill. Introducing self-service digital solutions can empower customers to resolve issues independently, reducing the need for immediate support.

At this stage, our design was informed by SMEs and existing research. To ensure the tool was practical and effective, we conducted 5 user testing sessions with Yarra Valley Water customers from various property types and sizes, assessing how easily they could navigate the process and identify a leak.

We needed to make usage and costs more relatable

A quick win was projecting usage and costs over clear time periods.

Customers were confused how many steps were involved for a leak test

  • Clearly outlined the number of steps when it came to the leak test section

  • Interactive checklist instead of an accordion for a more guided and engaging experience

Account for unexpected usage patterns

We added a section asking customers if they've had visitors to account for occasional spikes in water usage.

Notify

When customers are notified about a potential continuous leak, they receive an SMS with a link to verify their account details. After verification, they’re asked if they’ve had any visitors stay at their property, as this may have impacted their water usage.
