The nineteenth century extension wing of Meillionydd Fawr (NPRN 16516) had a basement dairy, with a waterwheel in a pit outside the west gable. The wheelpit still survives. Water came through ceramic pipes burind under the lawn, from a pond adjacent to the farm buildings and now filled. This wheel shared its water supply with the wheel at Meillionydd Stable (NPRN 411541), from an impounded spring at Ffynnon Cwm-dylif, SH2212529386.
