Customer Case Study
Barwon Water
Victoria
– One local farmer saved between 10 – 15 million litres of water
– Identified over 60 water leaks ranging from 5 litres/hour to over 60 litres/minute
Objective
Monitor water use on rural properties to quickly detect leaks and faults.
Details
Agricultural use accounts for 30% of annual potable water usage in the Colac supply system. Up to 15% of that water is lost through leaks on the farm, beyond the water meter. Such leakages are common due to the combination of pressurised water, small diameter polypipe networks and exposure to external factors like stock, frost, soil movement, stones, roots and UV light from the sun.
Located a few kilometres north-east of Colac in Victoria, farmers in the Irrewarra area were looking for ways to implement efficient water systems, save money and reduce the pressure on drinking water resources.
Method
Taggle worked with Barwon Water and the Irrewarra Farm Care group to trial Automatic Meter Reading (AMR) technology to better manage the use of potable water in agriculture.
The original trial consisted of a single Taggle receiver that receives hourly data from 75 transmitters fitted to farm water meters. It involved 25 farmers, who tracked their farm’s water usage on an hourly basis, by logging into a Taggle supplied secure website.
Sensors include;
200 Digital water meters
Results
The data helped the group identify over 60 water leaks, ranging from 5 litres/hour to over 60 litres/minute, which led to significant water bill savings. The Taggle meter reading network helped one local farmer (quoted in the local newspaper, Colac Herald) save between 10 and 15 million litres of water.
Due to the success of the trial, farmers in a neighbouring district requested an additional receiver and more tags, so more farms could monitor their water usage; there are now over 65 farms connected to the system.
Recently Barwon Water introduced an opt-in SMS alert system to notify busy farmers of an irregularity in their water usage from data provided by the Taggle network.
Bruce Bilney from Barwon Water: “The Taggle system provided valuable information, that we were able to use to identify when water was in demand by stock and adjust our water management accordingly, making sure there was enough water in quantity and flow to cover peak times. Previously the system was run to cope with peak usage 24/7 when, in fact, it was only needed for 2-6 hours on certain high demand days. That is, on hot weather days, not 365 days of the year. This resulted in water savings, as the system did not need to be constantly pressurised and, when there was a failure, it was not boosted by being pressurised. It also led to power savings through not having to run the pump around the clock.”
