The entire facility comprising the reservoir, valve house and remaining equipment is owned and maintained by Sydney Water.

The restoration of Gladstone Park and the erection of a bandstand was made a condition of construction of the reservoir.

[6] The facility was made redundant by the commissioning of Petersham Reservoir in 1965 and has remained disused ever since.

The neighbouring valve house was constructed in 1917[7] on the Booth Street frontage of the park and this, together with the footings of the bandstand, can still be seen today.

Restoration work on the valve house earned a National Trust of Australia Heritage Award in 2006.
