Built in the late C19 as part of the Rnodda Fach Water Scheme (nprn 309952) by the Pontypridd Water Works Co. Demolished, with most of the fabric removed from the site. It survives to plinth level, and is built of rock-faced sandstone, approximately 13m NW-SE by 9m. Internal banks suggest division into 4 units.
