Slurry Tank

The Slurry Tank is a large brick-walled structure, rectangular in shape, measuring approximately 49 by 29 meters. It is partially built into a bank on the west side and features a large tank in the center. The building is constructed of brick with a slate roof on the southern range. The main surviving section is to the east, which is two stories tall and has a 13-bay facade. This facade includes bullseye windows above round-headed doorways, two of which have boarded sliding doors, while three are partially blocked to create lunettes. The outer bays also feature smaller lunettes. Above the bullseye windows, there is a white brick dentil cornice and a parapet that extends down to window sill level, effectively creating a third storey.

The southern range has a wide doorway on the left with a rusticated surround and a horizontally sliding boarded door. To the right, there is a round-headed doorway accessed by a raised path with a brick retaining wall. The inner face of the southern range has six openings with segmental heads, four of which still have some original louvres, and beneath two of these openings are chutes that allowed muck to be swept into the tank. Below this area is a six-bay, barrel-vaulted undercroft that opens to the tank.

The northern range also has a similar undercroft but is mostly demolished. It features a short brick tunnel beneath a ramp to the northwest. The western range is similarly mostly in ruins. Although not inspected in November 1996, it is reported that in the eastern range, the ground floor doorways lead into rectangular cells, and the first floor contains a central full-length corridor with a brick vault. The interior of the southern wing is divided into pens.
