Water Meter Logging

Installation of Remote Water Logging Devices that continuously monitor water usage in townhouse complexes, flats & apartments, factories and shopping centres; helping you take control of your water consumption and prevent against excessive water loss.

How Our Remote Water Logging Meters Work

  • A logging device is attached alongside the property’s main water meter, or on individual unit meters within a complex.
  • The device sends water usage data using a radio frequency which is stored and monitored on our online database.
  • Water usage monitoring and meter reading is done remotely.
  • The moment water usage deviates from normal usage patterns, an alert is triggered – long before hefty municipal bills arrive.

Water consumption should decrease to a minimum at low demand times (between 1am and 4am).
If this minimum flow rate is significant, it is probable that there is a water leak.
The graphs below illustrate water use over time – each bar represents kilolitre water use per hour.

Water Meter Logging Reports

An example of a unit that has severe water leaks. For this  large townhouse complex with many leaks, the flow rate is never less than 3kl/hour. All the consumption in the red box is water loss. Even at 1 – 4am there is loss of 3kl/hour. Water use increases around 5.30am, peaks at 10am and then varies, dropping to the leak rate of 3000lt/hour towards 11pm.

Water Meter Logging Reports

A leak continued until detected on 19 July 2018. The leak was repaired on that day. The morning after, at 3am, the water use was zero.

Interesting Facts

  • 1litre per minute water loss is roughly 40 000 litres per month.
  • Towns generally lose 25% or more of water through leaking pipes.
  • If you suspect a pool leak, place a bucket on the first step and fill it to the same level as the pool. If the level of water in the pool drops below that of the bucket, then there is a leak.
  • If you suspect a water leak, close all taps and place your ear against a water pipe. If a faint hissing sound is heard, there could be a leak.
  • Water leaks usually start off very slowly, so small that they show little or no movement on the water meter. The leaks develop into larger leaks and may burst when there are spikes in water pressure.
  • The most common cause of water loss is poor pipeline installation and failure of fittings. Soil loading and excessively wet soil cause immense pressure on pipes and fittings. Pipes should be bedded in sand but this is usually not done. Angular rock fragments against pipes and poor connections are the main culprits.
  • As the leaks slowly erode sub-surface soil the water finds its way through the ground following lines of weakness in sub-surface pathways. Some leaks even as large as 500 000 lt/day may never show on the surface. The orientation of the leak, ground conditions and rock fragments above the pipe are the main reasons why leaks never show on the surface.
