Statement of significance:

Penshurst Reservoir (Elevated) (WS 87) and (WS 88) are one of a small group of four similar elevated reservoirs in the SWC system, the others being Bellevue Hill Reservoir (WS 10),1910, Drummoyne Reservoir (Elevated) (WS 38), 1910, and Ashfield Reservoir (Elevated) (WS 3), 1912. The group of reservoirs demonstrates a high level of engineering expertise and architectural detail, accommodating both structural requirements and aesthetic qualities. Penshurst Reservoirs and Site demonstrates the rapid growth in demand for water in Sydney's southern suburbs as well as exhibiting a wide range of reservoir construction technology. It is the key site connecting Woronora and Warragamba water supply since 1942. The site has been in continuous use for water supply since 1891, over 100 years. Penshurst Reservoir (Elevated) (WS 88) is the largest elevated reinforced concrete reservoir in the Sydney Water Supply System.

Description

Designer/Maker: Public Works Department
Builder/Maker: Public Works Department
Construction years: 1895-
Physical description: Penshurst Reservoir (Elevated) (WS 87) is one of a group of four similar elevated reservoirs, the others being Bellevue Hill Reservoir (WS 10),1910, Drummoyne Reservoir (Elevated) (WS 38), 1910, and Ashfield Reservoir (Elevated) (WS 3), 1912. Each reservoir is an elevated cylindrical riveted steel tank, resting on a concrete apron and supported on a steel girder frame. The perimeter of the steel stand has a façade of concrete columns and arches, which forms a decorative, rather than a structural feature. The walkway around the rim of the reservoir has been removed. Standard features include: handrail in tubular steel, davit, access ladder, depth gauge board, inlet and outlet valve chambers. Full Service Level: 92 m. Capacity: 6.6 ML. Penshurst Site. The Penshurst Reservoir Site also includes the former Water Service Officer's Cottage, the concrete base of Penshurst Reservoir No. 1, the brick stand for Penshurst Tank (1891), valves and pipework associated with the connection in 1942 of the Woronora supply with Upper Nepean System water and a number of skid huts (3 in total - see listing for Penshurst Reservoir (Elevated) (WS 88). Significant plantings around the site include: cypress, viburnum, jacaranda, camphor laurel, oleander and native species.
Modifications and dates: The reservoir has been roofed to safeguard water quality (1977).
Current use: Reservoir
Former use: Reservoir

History

Historical notes: In 1891 a cast iron elevated tank (0.09 ML) was constructed at Penshurst (only the brick stand still survives). It was supplied with Upper Nepean Scheme water by a pumping station at Carlton. To augment supply, Penshurst Reservoir No. 1 (riveted steel surface reservoir) was constructed in 1895. By 1910, further growth in demand was met with the construction of Penshurst Reservoir No. 2 (Elevated) (WS 87), a riveted steel elevated reservoir. (Penshurst Tank was removed in 1914, first to Campbelltown and in 1942 to Warragamba Township). The fourth reservoir, Penshurst Reservoir No. 3 (Elevated) (WS 88), a large concrete elevated reservoir, was constructed in 1938. Penshurst Reservoir (Elevated) (WS 87), built in 1910, is one of a group of four similar elevated reservoirs, the others being Bellevue Hill Reservoir (Elevated) (WS 10),1910, Drummoyne Reservoir (Elevated) (WS 38), 1910, and Ashfield Reservoir (Elevated) (WS 3), 1912. In the meantime, Lakemba Pumping Station took over supply for Penshurst in 1924, but also supplied Wiley Park and East Hills from 1930. Carlton pumping station continued in emergency service until decommissioned in 1939. Penshurst Reservoir No. 1 was removed in 1951 and re-erected at Newport. With plans to extend the Woronora Pipeline to the Metropolitan System, a Main was commenced in 1958 from Penshurst to Allawah. However by 1961, it was realised that instead of Woronora supplying Sydney, the opposite would be the case, with Warragamba water supplementing areas supplied by Woronora. This situation required further amplification of the mains between the City Tunnel at Ashfield and the Penshurst Reservoirs, including a new main from the City Tunnel to Allawah, pumped by a new pumping station in Canterbury Park, together with a pumping station at Allawah to pump water to Penshurst. Completion of this scheme in 1969 allowed Warragamba water to be fed into the Woronora Pipeline in sufficient quantity to assist in the supply of Sutherland, Cronulla and beyond.

Assessment of significance

SHR Criteria a)
[Historical significance]
Penshurst Reservoirs and Site demonstrates the rapid growth in demand for water in Sydney's southern suburbs as well as exhibiting a wide range of reservoir construction technology. It is the key site connecting Woronora and Warragamba water supply since 1942. The site has been in continuous use for water supply since 1891, over 100 years.
SHR Criteria c)
[Aesthetic significance]
Penshurst Reservoir (Elevated) (WS 87) and Penshurst Reservoir (Elevated) (WS 88) form a dramatic landmark on the skyline for the surrounding area.
SHR Criteria e)
[Research potential]
Penshurst Reservoir (Elevated) (WS 87) is one of a small group of four similar elevated reservoirs, the others being Bellevue Hill Reservoir (WS 10),1910, Drummoyne Reservoir (Elevated) (WS 38), 1910, and Ashfield Reservoir (Elevated) (WS 3), 1912. The group of reservoirs demonstrates a high level of engineering expertise and architectural detail, accommodating both structural requirements and aesthetic qualities. This reservoir site demonstrates the broad range and variety of construction techniques for water storage reservoirs.
SHR Criteria f)
[Rarity]
This reservoir (WS 87) is one of four riveted steel elevated reservoirs on a steel girder stand with concrete surround in the SWC system, rarer still because of the high level of architectural detailing.

WS 88 is one of a small group of elevated concrete reservoirs on a concrete pier stand. The largest of its type in the SWC System. The 'skid huts' are a rare survival, demonstrating former working conditions in the MWSDB.
SHR Criteria g)
[Representativeness]
The riveted steel tank was common technology for surface reservoirs, but was extremely rare when combined with an elevated steel frame with concrete apron.
