Statement of significance:

The Lewisham sewage aqueduct, completed in 1900, is a key and highly visible component of the Southern and Western Suburbs Ocean Outfall Sewer system. The extension of this system into Dobroyd Point provided for a sewerage service to the emerging suburbs of Haberfield and Ashfield. The aqueduct is considered unique in Australia for its riveted oviform steel carrier. The functional nature of the carrier is embellished by decorative metal lattice work, and worked sandstone faced piers and abutments. The setting of the aqueduct adjacent the stormwater channel and railway embankment/viaduct make a precinct of high historic and industrial archaeological interest. Elements of significance are the past and ongoing use, technologies of construction, and setting within the shallow valley.

Description

Designer/Maker: Sewerage Construction Branch, Department of Public Works
Builder/Maker: Sewerage Construction Branch, Department of Public Works
Construction years: 1900-1900
Physical description: The Lewisham sewage aqueduct comprises two principal elements - the metal oviform carrier, supported on concrete piers faced in sandstone rusticated blocks, with worked decorative bases and capitals. The carrier sections (the Public Work’s reports consistently give the material as steel) are riveted. The carrier is connected to the pier by two rocker plates and metal lattice supports. All of this appears original. The east and west ends of the carrier terminate within an abutment faced in worked sandstone. The Lewisham sewage aqueduct is situated within a wide, shallow valley north of the main western railway line, which is similarly carried over the valley by embankment and viaduct. Between Piers 2 and 3 of the aqueduct is a brick and concrete rendered stormwater channel (c.1899). These three elements of late nineteenth and early twentieth century public infrastructure in close proximity evoke an interesting industrial archaeological scene. The sewer carrier continues to serve as an integral link in the sewerage of the local area and is part of SWOOS.

History

Historical notes: The Lewisham sewage aqueduct was completed in 1900. The aqueduct was constructed for the Dobroyd Branch of the Southern and Western Suburbs Ocean Outfall Sewer (SWSOOS no.1). The aqueduct was designed and built by the Sewerage Branch of the Public Works Department (Contract No. 135). The design work was completed by March 1897. The engineer-in-chief of this department was Joseph Davis. The Dobroyd Branch is a sub-branch of the Main Northern Branch of SWSOOS, which services the areas of Marrickville, Petersham, Ashfield, Burwood, Drummoyne, Strathfield, Concord and Homebush. The Dobroyd Branch contract extended from the junction of The Boulevard/Hunter Street, Lewisham northwest to the Parramatta Road. The aqueduct carries sewerage from Dobroyd Point, Haberfield and parts of Ashfield. Part of this contract was let during 1897. By mid-1898 the piers for the aqueduct had been erected and the steel plates delivered. The Branch was completed by mid 1900 and transferred to the Water Board. The aqueduct was designed to carry sewage over Long Cove Creek stormwater channel near the Lewisham railway viaduct. The design provided for an aqueduct 280-ft. (85.3 m.) long with six spans (two spans of 40-ft. (12.2m.) and four spans of 50-ft. (15.2m.)). The sewer carrier is an oviform steel plate pipe 4-ft. 6-in. (1.4m.) by 3-ft 6-in (1.1m.) supported on mass concrete piers faced in worked sandstone blocks. The dimension of these piers varies. The tallest (Pier 2) is approximately 24-ft (7.3m.) with a base 10-ft. 6-in. (3.2 m.) by 6-ft. (1.8m.). The steel carrier rests on two fixed rocker supports on the central pier (Pier 3) with sliding rocker supports on the other four piers and at the abutments. The abutments were designed as stone faced. Within the embankment are a series (four each side) of mass concrete arches of about 8-ft. (2.4 m.) span. The contract drawings also indicate the carrier elsewhere within the embankment is concrete encased. The use of an oviform section for the carrier is to maintain a self cleansing velocity at low flows. Whilst common in sewer construction, it is not considered to be a requirement for metal carriers. The Lewisham sewage aqueduct (1900) is one of six sewage aqueducts in Sydney completed in the period 1895-1901. Others include the reinforced concrete ‘Monier’ arches at Whites Creek and Johnstons Creek (1897), the mass concrete/brick arches and iron pipe at Wolli Creek and Cooks River (1895), and the Mosman Bay steel arch (1901).

Assessment of significance

SHR Criteria a)
[Historical significance]
The Lewisham sewer aqueduct, completed in 1900, is a key and highly visible component of the Southern and Western Suburbs Ocean Outfall Sewer system. The extension of this system into Dobroyd Point provided for a sewerage service to the emerging suburbs of Haberfield and Ashfield, both of which experienced marked development during the 1900s to 1920s.
SHR Criteria c)
[Aesthetic significance]
The functional nature of the carrier is embellished by decorative metal lattice work, and worked sandstone faced piers and abutments. The setting of the aqueduct adjacent the stormwater channel and railway embankment/viaduct make a precinct of high aesthetic note.
SHR Criteria d)
[Social significance]
The aqueduct is a major element of the historic built environment of the local area, which due to its location adjacent the railway line is likely to be known to some of the Sydney community.
SHR Criteria e)
[Research potential]
The aqueduct is considered unique in Australia for its riveted oviform steel carrier
SHR Criteria f)
[Rarity]
Rare in Australia in consideration of the extent and date of the steel carrier.
SHR Criteria g)
[Representativeness]
Representative in its function which is widespread across Sydney.
