Roman Water Tank east of Brunant Farm is a stone-built storage structure dating to the Roman occupation of Wales. The tank was constructed to hold water for the supply and use of the Roman military or associated settlement in this upland area. Built upon bedrock of Ashgill mudstone, siltstone and sandstone, the tank demonstrates Roman engineering adapted to the local geology of this remote Welsh landscape.
The presence of such infrastructure indicates organised Roman presence in the locality, where water from natural sources would have been gathered and distributed. The choice of location, anchored to the Ashgill bedrock formations, provided a stable foundation for the structure and ready access to water sources in the surrounding terrain. The tank represents the practical hydraulic technology that underpinned Roman military installations and civilian settlements across Britain.
The monument is protected by Cadw, the Welsh heritage organisation, under reference CM237. It survives as archaeological evidence of Roman Wales beyond the main forts and villas, revealing the extent of Roman infrastructure investment in Wales and the engineering solutions employed to sustain occupation in upland regions where natural water resources required formal capture and storage systems.
