  • Physical description
    Bantry Bay Reservoir (WS 8) is a cylindrical reinforced concrete reservoir, with slightly tapering sides. It is connected by overhead walkway to the adjacent Bantry Bay Reservoir (WS 221). Standard features include: concrete apron, davit, depth gauge board, access stairway, handrails and inlet and outlet valve chambers. Bantry Bay Reservoir (WS 221) is a welded steel reservoir and is not significant. Within the grounds is a small meter house, originally housing a Venturi meter, but only with the pipework remaining (the meter has been removed). A skid hut has also been re-used as a meter house. Full Service Level: 133 m. Capacity: 6.9 ML.
  • Modifications made
    The reservoir has been roofed to safeguard water quality (1960s-1970s). A new Air Inlet Control Valve (AICV) installed 2000.
  • History
    Manly Reservoir (WS 64) was constructed in 1892 and was supplied from Manly Dam (1892), by pump located just below the dam wall. Manly water supply was independent of the Metropolitan supply from the Upper Nepean Scheme until 1906, when a gravity main was completed from Mosman Reservoir. An elevated tank was erected beside the Manly Reservoir in 1916, but was made redundant and demolished in 1924, when Bantry Bay Reservoir (WS 8) was completed. Supply from the Manly Dam was phased out by 1933 when Bantry Bay Reservoir (WS 8) was connected by main to Pymble Reservoir. Manly Reservoir was built by the NSW Department of Public Works and owned by Manly Council, until it was transferred in 1902. Bantry Bay Reservoir (WS 8) was built by the MWS&DB. Manly water supply was integrated into the Metropolitan supply in 1933, when Bantry Bay Reservoir (WS 8) was connected by main to Pymble, thus making Manly Dam redundant for supply needs.
