In this episode of Ear to the Ground, host Ifan Jones Evans visits Wallog, a coastal sheep farm perched on the rugged Cardigan coastline near Clarach, Ceredigion. Wallog has long faced the challenge of ensuring a reliable drinking‑water supply for its flock of outdoor‑lambing ewes, relying on an ageing system of seasonal springs, wells and reservoir tanks in one of Wales’ lowest rainfall areas.
With pumps working hard to move water uphill through difficult terrain—and an old pipe network vulnerable to leaks—the farm has historically struggled with high electricity use, water loss and inefficiency.
But change is underway.
Guest David Evershed shares how he is embracing LoRaWAN technology to monitor water flow across the farm in real time, detect leaks early and ultimately automate water pumping. The vision? A smart, energy‑efficient system powered by newly installed photovoltaic (PV) panels—reducing waste, cutting costs and securing the farm’s water future.
Join us for an insightful conversation exploring how digital innovation and renewable energy are transforming traditional farming challenges at Wallog.
