The Pymble Reservoirs No. 1 and No. 2 are two heritage-listed reservoirs located at Pacific Highway in the Sydney suburb of Pymble in the Ku-ring-gai Council local government area of New South Wales, Australia. The reservoirs are also known as Pymble Reservoir No. 1 (Covered) (WS 0097) and (WS 0097); and Pymble Reservoir No. 2 (Covered) (WS 0098) and (WS 0098). The property is owned by Sydney Water, a State-owned statutory corporation of the Government of New South Wales. The reservoirs were added to the New South Wales State Heritage Register on 15 November 2002. History Northern Suburbs Supply When the Board of Water Supply and Sewerage took over from Sydney City Council in 1888, the only supply to the northern suburbs was by a submarine main from Dawes Point to Milsons Point, taking water by gravitation from Paddington Reservoir. The level of Paddington Reservoir limited supply to the lower areas of Northern Suburbs. In 1888, in order to overcome this problem, the Board erected a pumping station in Junction Street, , with two storage tanks in the grounds of St. Thomas' Church, to meet demand for the higher parts of North Sydney. The plant was dismantled in 1892, the pump being transferred to Carlton and the tanks to Wahroonga. The above submarine main was abandoned in 1917. In 1892 the Ryde Pumping Station was commissioned, supplied by mains from Potts Hill (via Rookwood Cemetery, along the Concord Peninsula and attached to the 1889 railway bridge at Meadowbank), with reservoirs at Ryde Pumping Station (disused 1930) and Ryde Hill and then by mains to a pair of reservoirs at Chatswood (previously constructed in 1888). With increasing population of the North Shore, brought about by the construction of the railway, new storage reservoirs were required. The tanks, originally at N Sydney, were transferred to Wahroonga in 1896. A steam powered pumping station was erected at Chatswood in 1895 for the supply of Wahroonga. A new steel surface reservoir was constructed at Wahroonga in 1898. From Wahroonga the main from Chatswood extended to Hornsby, with a branch to Thornleigh and Beecroft. Both Pymble Reservoir No. 1 and Pymble Reservoir No. 2 were constructed in 1900 to meet local supply. The mains from Chatswood to Wahroonga had deteriorated by 1905, necessitating new direct mains from Ryde to Wahroonga, and from Chatswood to Pymble to connect to the former main.
