The reservoir is rectangular in shape, measuring Шаблон:Convert and is Шаблон:Convert tall. It is divided into two chambers by a Шаблон:Convert separating wall which supports a walkway. The reinforced concrete roof and park above are supported by concrete pillars spaced at Шаблон:Convert intervals throughout both chambers.
Access to the reservoir is through the adjoining valve house which extends a further two storeys underground and housed pumping equipment in the lowest level.
The entire facility comprising the reservoir, valve house and remaining equipment is owned and maintained by Sydney Water.[1][3]
History
Balmain reservoir was built in 1915 by the Metropolitan Board of Water Supply and Sewerage, Sydney, and was originally supplied with water by gravity from Potts Hill. The restoration of Gladstone Park and the erection of a bandstand was made a condition of construction of the reservoir.[4] 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[5] 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.
