  • Statement of significance
    SPS 27 is of historic and aesthetic significance at the local and state level. Its historic value is derived from its original function which was to serve the Bondi Ocean Outfall Sewer (BOOS). The construction of the BOOS effectively ended the discharge of untreated sewage into Sydney Harbour. It is a rare example of the use of local sandstone as an architectural material in an industrial building designed by the Water Board, and was designed to lend stylistic continuity to the surrounding buildings in the Callan Park complex. In addition, the mechanical components housed within the building have potential industrial archaeological value. The Station is located within a small site adjacent to Eastern Park. The structure thus has a level of aesthetic value which is enhanced by its location in picturesque Iron Cove and contributes significantly to the visual catchment of the surrounding landscape.

  • Physical description
    SP0027 is a decommissioned low level sewage pumping station located within the grounds of the former Callan Park Hospital, Rozelle. It consists of two distinct parts; a superstructure comprising a small single storey loadbearing sandstone building; and a substructure constructed of concrete which houses machinery and sewage chambers. Architecturally, the building was designed in a utilitarian version of the Federation Romanesque style and was intended to be stylistically sympathetic with the nearby Kirkbridge Block of Callan Park Hospital. Externally there is an original hipped corrugated iron (roof sheeting later) roof topped with a louvered ventilator; boxed eaves; random course picked sandstone walls; original multi-paned timber framed fixed sash windows with multi-paned fanlights and dressed sandstone surrounds. The entrance consists of an original timber framed, ledged and sheeted double doors. Above the door is a recessed sandstone panel inscribed with "MBWS&DB 1911". Internally there are original exposed timber trusses arranged in a cruciform pattern framing the ventilation shaft. Walls are of painted picked sandstone with rubbed sandstone door and window dressings. The machinery well is currently filled with sand. There is a dwarf brick wall and 1.8m high cyclone fence surrounding three sides of the site, with the rear of the site abutting a natural stone outcrop. There is a small brick WC adjacent to the station. Area around the site has been concreted. Station overlooks Iron Cove and is located within a park-like setting.
  • Modifications made
    2014 - conservation works completed to the building, including replacement of sheet metal roofing, reinstatement of timber windows with protective brass mesh screens. Site drainage improved, new perimeter fencing installed. Paint was stripped from interior. By the early 1990s investigations revealed that the existing structure of SP0027 had reached its useful life. The walls of the wet wells and the dry well were not reinforced and in poor condition. Grading of the wet well floors was inefficient, leading to a heavy buildup of silt and rubbish that could not be flushed. Water was present in the concrete walls of the dry well at an average depth of 25mm. In addition, the electrical and mechanical equipment of the station was in poor condition with no replacement parts being readily available and the station caused a number of breakdowns of the rising mains in the 1990s. The conclusion was made that the station was at the end of its useful life and was structurally unreliable. Five options were considered for the renewal of the station and the preferred choice was to construct a new submersible sewage pumping station in a new location, adjacent to the existing station. At the time of the preparation stage of the renewal project there were no legislative controls in respect to heritage in relation to the SP0027 site. It was, however, recognized that the pumping plant and features of the building might be subject to the relic provisions of the Heritage Act, 1977 (NSW). The pumping units were inspected in September 1992 and were considered to be of high heritage significance. Sydney Water’s Environmental Scientist (Heritage) stated that the pumps and pipework appeared to be original; with some pipework identified as 1911 (the motors were replaced in the mid-1950s). The installation of the machinery was unusual in that two stages of the pump, driven by a common shaft, was mounted on opposite sides of a large cast iron bed plate and connected in series. In 1994 SP0027 was included in a thematic survey of all Water Board sewage pumping stations that determined the relative significance of SPSs and provided guidelines for the future maintenance and conservation of those stations identified as having heritage significance. As a result of the outcome of this study, SP0027 and many other sewage pumping stations were included in Sydney Water’s heritage register. The new wet well of SP0027 was put on line with effect from 2nd June 1997 and remained for trial run for 14 days. The old SP0027 was decommissioned on 16th June 1997. Sydney Water’s Product Delivery had no further use for the decommissioned station site and building. After the completion of a contamination survey in March 2000, the site was transferred to the Group Property Management for future maintenance. The dirt track leading to SP0027 had been sealed and became part of the Iron Cove foreshore walk, providing an important access between Callan Park and King George Park.
  • History
    In 1859 Sydney's sewerage system consisted of five outfall sewers which drained to Sydney Harbour. By the 1870's, the Harbour had become grossly polluted and, as a result, the Government created the Sydney City and Suburban Health Board to investigate an alternative means of disposing of the city's sewage. This led to the construction of two gravitation sewers in 1889 by the Public Works Department: a northern sewer being the Bondi Ocean Outfall Sewer and a southern sewer draining to a sewage farm at Botany Bay. Low lying areas around the Harbour which could not gravitate to the new outfall sewers continued to drain to the old City Council sewers. Low level pumping stations were therefore needed to collect the sewage from such areas and pump it by means of additional sewers known as rising mains, to the main gravitation system. The first comprehensive low level sewerage system began at the beginning of the 20th century when the Public Works Department built a group of 20 low level pumping stations around the foreshores of the inner harbour and handed them over to the Metropolitan Board of Water Supply and Sewerage in 1904. Overall, greater Sydney now has over 600 low level sewage pumping stations.

  • Local description
    Relates to the planning, development, expansion and provision of sewerage services.
  • a) Historical
    SP0027 Rozelle was completed in 1912 and is among the early low level sewage pumping stations constructed to serve the Bondi Ocean Outfall Sewer. Its construction evidences the growth of Sydney and expansion of municipal services during the early part of the 20th century. It is a rare example of the use of sandstone as an architectural material in an industrial building designed by the MBWS&S, and was designed to lend stylistic continuity to the surrounding buildings in the Callan Park complex. Prior to this sewage pumping station, the sewage entered Iron Cove through an outfall. This was the responsibility of the Health Department.
  • c) Aesthetic
    SP0027 is an excellent example of a robust and well proportioned small scale industrial building displaying Federation Romanesque characteristics in its surviving fabric, including picked sandstone walls and contrasting rubbed sandstone door and window dressings. Located in a picturesque setting adjacent to Iron Cove, SP0027 has landmark value. It is an excellent example of a public utility building designed to match the architectural character of the neighbouring prestigious public facility, the Kirkbridge Block of the Callan Park complex.
  • d) Social
    The station has been identified in a LEP and is part of a National Trust Urban Conservation Area and therefore is important to local community groups.
  • f) Rarity
    The station is a rare and unique example of a stone sewage pumping station within the SWC system and likely NSW.
  • g) Representative
    The station is a representative example of a small scale pumping station in the Bondi Ocean Outfall Sewer System.
