David Evershed

Wallog, North Ceredigion


Drinking-water availability has always been a concern for the sheep farm, Wallog, located on the Cardigan coast, near Clarach, Ceredigion. In a low rain-fall area of Wales, the farm relies on an ageing network of seasonal springs and reservoir tanks to ensure continuous water supply for their flock of out-door lambing ewes and for the dwelling.

With the rugged terrain at Wallog and awkward locations of reliable springs forcing the use of electric pumps to move water from wells to reservoirs before being gravity fed to required locations, electricity consumption is always a concern. Adding to this is the possibility of leaks in the ageing network of pipes and troughs leading to further energy usage and water wastage.

In order to conserve energy and water, David Evershed is looking to use LoRaWAN technology to detect and stop leaks as soon as possible, with the end goal of automating 
the pumping of water, utilising energy produced by recently installed photovoltaic (PV) panels, in order to conserve energy and water.

The project will also contribute to the Sustainable Land Management outcomes including:

  • Clean water
  • High animal health and welfare
  • Mitigate food and drought risk
  • Reduce greenhouse gas emission
  • Resource efficient
