Well Inspection & Interesting find today

We have had a well inspection to do today and also came across an interesting find while looking at a neighbours well. Is it actually a well. Extremely well built brick arches and brick built walls. All under the ground outside the property. We did not expect to be finding such a hidden gem however it does require some more investigation. Plenty of ground water within the water well however so client is happy and cannot wait to be using the water for the garden.
