Little Hay Pumping Station and the two front entrance gates and gate piers

Little Hay Pumping Station is a water pumping station built in 1929 for the South Staffordshire Waterworks Company. The chief engineer was F J Dixon. It is designed in the Free Renaissance style and is constructed of brick with red Hollington stone dressings.

The building has a rectangular plan aligned north to south. It is a single-storey structure with a basement. The west-facing front elevation comprises seven bays. The centrepiece is a wide stone entrance with a deep lintel inscribed "LITTLE HAY / 1929" and modern double doors. On either side of this entrance are three full-height segmental-arched windows with glazing bars and margin bars, and keyed architraves. At each end of the elevation are rusticated pilasters with stone capitals; similar vestigial stone capitals appear between the windows. Above runs a narrow cornice and coped parapet. Within the parapet are raised circular panels and a wide central stone frieze inscribed "SOUTH STAFFORDSHIRE WATERWORKS COMPANY". The basement projects from the west front to form a railed terrace with a panelled front. Central steps divide at the bottom, with a bow front topped by railings with ball finials. The side elevations comprise three shallow-gabled bays. At basement level are a central entrance (with modern doors on the south elevation and brick infilling on the north elevation), flanked by two metal casement windows. Above are three full-height windows in the same style as the front elevation, with the central window set forward. At the rear is a three-storey office and services bay with a central first-floor taking-in door on the east elevation and an irregular arrangement of metal casement windows. The roof is topped by a glass lantern.

Internally, the plan has remained largely unaltered with only minor changes to internal divisions within the rear office range. The large central engine hall has red, green and cream tiled walls and a red tiled floor arranged in a herringbone pattern with blue tile detail. An overhead cast-iron crane gantry is supported by pilasters. The roof is supported by reinforced concrete arched roof beams. The hall still contains parts of one of the two original six-cylinder four-stroke heavy oil engine pumps supplied by W H Allen and Sons of Bedford. One of the two cast-iron stairs from the main hall to the basement level survives. The basement contains brick tanks, drains and maintenance corridors. Most original internal timber doors survive, as do the foundation plaque and original temperature and depth gauges. To the rear is a tiled manager's office with a framed historic plan of the pumping station fixed to the wall, service rooms and a cast-iron staircase. The later electric pumps, other modern pumping machinery, control centre and modern plant are not of special interest.

The listing includes two sets of rusticated brick gate piers with metal gates in front of the building. Excluded from the listing are the timber boundary fence, corrugated sheds to the rear, a brick water treatment building, septic tanks, and the original septic tank located 22 metres to the south-east.
