Data Logging Program

We've been running our data logging and leak detection program since 2012, to help major water users become more efficient.

A data logger is a small device that is fitted to your water meter which measures water use throughout the day.

Data loggers are supplied with a 3G SIM card which enables high resolution water consumption data to be transmitted to a website via the mobile phone network. Customers are then able to analyse this data to ensure water wastage (through leakage, faulty equipment or excessive irrigation) is minimised.

This free program is available to non-residential sites using less than 20 million litres of scheme water annually, that are currently participating in one of these programs:

  • Waterwise Councils Program
  • Waterwise Aquatic Centre Program
  • Waterwise Office Program.
  • Data loggers show you how water is used at your property.
  • They identify issues such as leaking pipes, broken fixtures and incorrectly set irrigation systems, which have the potential to waste millions of litres of water annually and are relatively cheap to resolve.
  • Financial savings due to reduced volumetric water and sewerage charges.
  • Improved environmental performance by using less water to deliver the same products and services.
  • The ability to demonstrate your commitment to Corporate Social Responsibility and advertise your environmental credentials.

How data logging can help you understand your water use

Data loggers can show baseflow, which is constant water use that is evident 24 hours a day. Baseflow should always be investigated to help you understand where your water is going.

In some cases like a manufacturing plant, which operates non-stop without regular shutdown periods, baseflow might not imply a leak. In these cases, data loggers can still identify issues when shutdowns for maintenance occur.

However, for most businesses, continuous water use overnight, particularly in the early hours of the morning represents an opportunity for investigation. Even in businesses like hotels that have people on site 24 hours a day, the water use should still return close to zero during this time.

By installing isolation valves into your plumbing network, you can isolate various areas of your site by turning water off to a specific area only. If the baseflow visible on the data logger then disappears or is reduced, it indicates that this is the area you should investigate further.

Not only does this save time for your plumber but you will save money too.

A customer was alerted to unusual use levels via a data logger. This prompted an investigation that identified a leak which was responsible for around 33% of the property’s water use.

 Initial usage report from a data logger which identified unusual activity

Issue:

Wet grout on the pavement identifies a possible leak area

After being alerted to a possible problem, staff noticed wet grout on the pavement (this was previously not identified due to regular cleaning).

First pavers lifted in the search for a possible leaking pipe

Lifting the pavement exposed very wet ground, despite the area being dry for a number of days.

A leaking pipe is exposed under the paving

After turning off the water, staff dug down to expose a leaking pipe.

With the water turned back on, the hole filled up very quickly

After turning the water back on, the hole filled up very quickly.

Result:

The hole in the pipe that was causing the leak, alongside a ruler which measures it at approximately 25mm

A small hole created a leak that if left unresolved would have wasted around eight million litres of water a year and cost the customer around $34,000 annually.

The site saw their average daily water use drop by a third after the leak was repaired.
