Statement of significance:

The strategic use of polychrome brick work and moulded brick details along with a considerably intact entrance fence and shaft make this structure arguably the most elaborate one of its type left in the Sydney Water system, or in NSW. The quality of workmanship and detailing is unlikely to be seen again in this type of structure. The shaft is a landmark in the area which can be seen as far as surrounding ridge tops.

Description

Designer/Maker: NSW South Wales Public Works Department
Construction years: 1909-1909
Physical description: Located some 25 metres north of Hunter Street and fronting the Boulevard is a Queen Anne revival brick and stone fence and timber entrance doors behind which is the brick and stone vent shaft. This shaft is an excellent example of the brick and stone masons craft built in 1909. The overall height of the vent shaft is approximately 9 storeys with rubbed red and cream glazed brick decoration. The pedestal is octagonal in plan with the shaft emanating at a stone transition to circular in plan with entasis from the base. The bottom of the pedestal is coursed rock faced stone to rusticated stone to 19 courses of English bond brick, upon which is the stone transition course from octagonal to circular. The pedestal extends in a circular brick form of 36 courses in English bond to a stone coursed base of the shaft, the brick shaft being surmounted by a stone course with brick cap. It is possible there was a decorative cowl however there is no evidence of that now. Directly around the base is a reconstructed federation period domestic dwelling (using the base as part of their land use). Across the road in the Boulevard is a public school and the remaining houses surrounding the vent shaft are generally detached late Victorian and Federation period dwellings. The vent shaft is particularly noticeable on the vista from Wardell Street.

The pediment above the entrance reads MBW-S&S 1909.

The entrance doors are in timber and likely to be original although the panels may be later.

The structure is substantially intact and in good condition apart from the need for repointing in strategic places particularly of the fence and in areas of the shaft. Three steel bands are fitted to the upper portion of the shaft to assist in stabilising the fabric. The fence in its design and scale sits well with the adjoining streetscape.
Date condition updated:20 Jun 00
Modifications and dates: Steel straps to the shaft added mid to late 20th Century.
Current use: Sewer Vent Shaft
Former use: Sewer Vent Shaft

History

Historical notes: The Northern Branch Main sewer was partly completed by 1901 and was completed before the Western Main Branch. This Branch was a siphon at the low point in Illawarra Road near Sydenham Road. The siphon is maintained by the sewage being diverted temporarily to SPS 271 for flushing purposes. This pumps it to the Eastern Branch Main Sewer.

The Dobroyd Submain discharges into this Branch at Lewisham at the point where the Lewisham Vent Shaft is located. This vent was completed in 1909 and is only one of a handful of like shafts in Sydney Water system.

Recommended management:

Manage the place and its significant components in accordance with the Heritage Council State Owned Heritage Asset Management Guidelines and the Minimum Standards of Maintenance and Repair in the NSW Heritage Regulations. Manage significant site elements in accordance with a Conservation Management Plan (CMP). If no CMP exists, consult with Asset Management Commercial Services with respect to commissioning a CMP. When commissioning a CMP, do so in accordance with the Model Brief for CMPs available on ConnectNet. Seek endorsement of the CMP from the Heritage Council of NSW. Works undertaken in accordance with a Heritage Council-endorsed CMP do not require further approval under the NSW Heritage Act. Involve heritage professionals as required under the terms of the CMP, or as otherwise determined necessary. Review CMP every 5 years or in a major change of circumstances, whichever is sooner. Review of a CMP should only be undertaken following consultation with Asset Management Commercial Services . When commissioning a CMP review, do so in accordance with the Model Brief for CMPs available on ConnectNet. Where no CMP is in place, or where works are outside the scope of the existing CMP, assess heritage impacts of proposed works in accordance with Sydney Water Environment Impact Assessment guidelines (e.g. undertake a Heritage Assessment and/or Statement of Heritage Impact as required, obtain Heritage Council approval as required). Consult with the Heritage Manager, Environment and Innovation, when major works are planned which affect items of State heritage significance. Undertake archival and photographic recording before major changes, in accordance with Heritage Council guidelines. Lodge copies of the archival record with the Sydney Water Archives and the NSW Heritage Office. Where the item is listed in a Local Environmental Plan Schedule of Heritage items, determine if works are exempt from approval under the LEP provisions. Where works are not exempt, obtain necessary approvals from the local council, in accordance with SWC EIA Guidelines.
