eastern elevation below a rendered hood mould over the door. A galvanised corrugated iron shed is located a metre to the north of this vent stack over the manhole to the main. The location of the site of the vent shaft is directly off Paisley Road and is a triangular site all now paved in concrete. Adjoining development is domestic since the early 20th century, and across the road is the railway line. Condition overall would appear to be good with some evidence of horizontal cracking towards the upper portions of the pedestal. Some spalling is evident up the shaft. A lightning conductor is located on the southern side of the shaft. The vent shaft is prominently located and the surrounding topography makes this shaft a landmark for a considerable distance from most vantage points. A lack of large scale and high-density buildings contributes to its relatively open visual qualities within this urban environment. This shaft has a larger scale base than that of the Wentworth Road shaft. Evidence remains on the street frontage of an original timber gate post some 6 inches squared with original coach bolts and gudgeons still in place. A late 20th century wire cage gate and steel frame is now fitted to the entry of the site. The shaft and its surrounding fence have little if any immediate streetscape value or give little if any contribution to the surrounding dwellings, although its landmark quality to the broader townscape is most notable. The paling fence would appear to be late 20th century and not original. Considerably intact. The vent is considered unpopular by many members of the Croydon population, this is most likely due to its industrial and rather conflicting place in the Croydon skyline. Heritage listing As at 4 January 2001, the vent shaft is a locally prominent landmark and one of only two like structures in Sydney Water's system, which plays an important function to the main western sewer system. The unusual design and reinforced concrete construction is rare for this type of vent on a State level. Croydon Sewer Vent was listed on the New South Wales State Heritage Register on 15 November 2002 having satisfied the following criteria. The place is important in demonstrating the course, or pattern, of cultural or natural history in New South Wales. The vent has tangible historical associations with the western branch main sewer and through the
