  • Statement of significance
    The Stanmore Sewer Vent is an item of significance for the Sydney area and Sydney Water for its role in an important stage of development of the sewerage services to the Inner Western Sydney suburbs area. The aesthetically appealing historic ventstack contributes significantly to the understanding of the development of design of special sewer vent shafts in Sydney and NSW. It demonstrates the excellent technical and aesthetic qualities of the masons’ craft of the classicist late Victorian Sewer Vent. The Stanmore Sewer Vent is also of significance as a prominent local area landmark, identifiable from a further distance and a notable element of the Stanmore landscape.

  • Physical description
    The Stanmore ventshaft is constructed of moulded bricks. The stack is of circular profile, on a circular rendered-stone pediment. The overall height of the ventstack is about 15m, the pediment about 1.5m. The base of the ventstack features a single steel door, about 1.5m in height, facing the house and accessible from the property yard. The ventstack narrows to the top, featuring a generally classicist proportion. The bonding features two sets of decorative cornices of terra-cotta elements, concentrated by the bottom and by the top of the stack. The shaft is fitted with five steel bands in the lower half of the stack, apparently fitted in the late 20th century.
  • Modifications made
    The Corunna Road cottage has been sold and is no longer in Sydney Water ownership or management. The Stanmore Sewer Vent remains in Sydney Water's ownership and management.
  • History
    Special ventilation shafts were created where non-standard, relatively large vent heights and diameters were required. The standard iron shafts typically did not exceed 12 inches (30cm) in diameter and 48 feet (14.5m) in height, while the special shafts were commonly between 18 and 36 inches (45-91cm) in diameter and up to 45 metres high. The general expansion of sewer ventilation also affected the special shafts. The Annual Report for 1894 notes eleven special shafts and watersprays, seven of which were factory and boiler-room chimneys. By 1901, this number increased to forty. The purpose built special vent shafts of the late 19th century were elaborate masonry masterworks, designed as local landmarks and often featuring decorative capping and bonding of bricks. A similar style was applied to other special ventshafts created around this date, including the ventshafts at Premier Street, Marrickville, and Corunna Road, Stanmore. The latter was in the 1890s referred to as Percival Road, Petersham. The M.B.W.S.&S Annual Reports noted that: Brick shafts of neat design have been erected in main outfall sewers at Premier Street in Western Suburbs system and at North Sydney Park in main sewer of that system. The shafts are effective and fulfil the purpose for which they were erected. The sewer vents in Premier Street, Marrickville and Corunna Road, Stanmore appear to be the only ventilation shafts ever built in NSW that feature associated accommodation facilities. The cottages were initially leased to Water Board employees engaged with the maintenance of the ventshafts. The early tenants’ names were recorded in the Sand’s Directories. The two ventshafts feature classicist design style, however the influence of pseudo-vernacular Queen Anne Revival style as introduction to the early Art Nouveau way of thinking throughout the world – in Australia referred to as the Federation period – is also evident. The shafts, featuring a diameter of 30 inches (approx. 75cm) were among the large special vents at the time of creation although not the largest in the system. Little documentation regarding the history of the Stanmore sewer vent has survived. The vertical cracking was stopped as the ventshaft was equipped with five iron fastening straps in the lower portion of the stack. The current set of straps was apparently installed in the 1990s, along with the new lightning conductor installations fitted to the side of the stack. The original lightning conductor eyelets also survive along the shaft. The Stanmore Sewer Vent maintains its original function within the SWSOOS system, like the other four SWSOOS sewer ventilation shafts listed on the State Heritage Register.

  • a) Historical
    The Stanmore Sewer Vent was created during an important stage of development of the sewerage services to the Inner Western Sydney suburbs area. The adjoined cottage demonstrates the custom of Sydney Water’s predecessor organisations to accommodate operational and maintenance staff on the site. The cottage has been sold and is no loner in the ownership or management of Sydney Water. It remains on the SHR. It was occupied originally by a former employee’s family is a particularly interesting demonstration of the then Water Board’s social responsibilities. The property lot features intact original boundaries. The front garden shape is irregular, determined by the presence of the ventstack. The lot is representative of the original land subdivision pattern in the local area.
  • c) Aesthetic
    Aesthetically, the Stanmore Sewer Vent is one of the finest surviving samples of a brick sewer vent in Sydney and NSW. The vent is a landmark in the local area. Technologically, the ventstack is an important engineering and civil services item, created in time when relatively low cost of masonry works allowed manual creation of large-scale structures. The dimensions of the stack are in themselves representative of the high technological standards of brick building at the time of creation. It is considered that the Stanmore Sewer Vent meets this criterion on the State level. The cottage does not meet this Criterion.
  • d) Social
    The Stanmore Sewer Vent is likely to be of value to the members of local community as a prominent landmark and for the function it serves in provision of sewerage services for the community.
  • e) Research
    An excellent example of brick masons trade in the precision of such detail including entasis of the shaft. The Stanmore Sewer Vent plays an important technical role in the provision of fresh air for the system and is a highly significant element to the sewer system.
  • f) Rarity
    The Stanmore Sewer Vent is a rare example of a sewer vent built in association with adjoined with cottage. The only other similar example known in NSW is the Premier Street, Marrickville sewer vent and two cottages. These are probably the only two such groups ever built in NSW and possibly Australia.
  • g) Representative
    The Stanmore Sewer Vent, is demonstrative of the late Victorian period design of brick-built ventilating stacks and chimneys. The cottage is representative of the Queen Anne architectural style, relatively popular around the turn of the 20th century. The Stanmore Sewer Vent was created in the period when special vent shafts were already well developed, purpose designed and built, and when their use was met with a full appreciation in the professional and general public. While almost every element of the group of special vent shafts erected in Sydney between 1857 and the 1920s is unique by the nature of its design, the Stanmore vent stands out as one of the most notable in aesthetic and technical terms. The Stanmore Sewer Vent is representative of the mature stage of design and development of special vent shafts, characterised by highest aesthetic values and craftsmanship virtues of the Victorian and Federation period. It is also representative of the transition from classical to the arts and crafts design.
