Statement of significance:

The Willoughby - Chatswood stormwater system represents one of the early examples where a stormwater and sewerage system were built separately of each other within the same catchment area. The Willoughby - Chatswood sewerage system and stormwater system have similar catchment boundaries and drain to the same location, Scotts Creek. However they were constructed as separate systems and this is significant as it represents the modern way of providing health services to the community.
Prior to the commencement of this stormwater system (1911) the general practice was to build combined sewers first and then build a separate sewer system at a later date.

The operational curtilage of SWC No. 26 includes the channel bed, walls & coping. The visual curtilage of the channel will vary along the length of the channel depending on the surrounding cultural landscape and landuses.

Designer/Maker: Public Works/ Water Board/Council
Builder/Maker: Public Works/Water Board/Council
Construction years: 1911-1968
Physical description: This stormwater channel drains an area of approximately 200 hectares. It is situated on the eastern side of the Pacific Highway and contained entirely within the Municipality of Willoughby. The system is bounded roughly by Mowbray Road, Sydney Street, Penshurst Street, Boundary Street and Pacific Highway, Willoughby.

Proceeding upstream from the outlet on the eastern side of Penshurst Street, Willoughby, about opposite the prolongation of Lamette Street, a general south westerly direction is followed towards Chatswood Station where the system terminates.

The stormwater channel is approximately 2.76 km in length and is constructed of brick ( 53%) and concrete (47%). The channel cross-section consists of box (21%), pipe (27%), open channel (15%) and covered sections (37%).

The following branches and amplification lines bifurcate from the main channel;
* Amplification Stage 2 Line 2 - Commences at Archer Street and extends along Albert Street to Chatswood Station.
* Amplification Stage 1 - Is located in Havilah Street and Victoria Avenue, Chatswood.

History

Historical notes: The Willoughby - Chatswood stormwater system was constructed progressively between 1911 and 1968. It was built by the Board, PWD and Local Council under various contracts. These include the following;
* Contract 1807 - This section extends from Penshurst Street upstream to Victoria Street, Chatswood. It was constructed by the Board in 1927.
* D.L. 1127 - This section extends from downstream of Bauldry Street to to the eastern side of Bauldry Street. It was constructed by the Board in 1919.
* Government Contract 1006 - This section extends from downstream of Bauldry Street to Victor Street, Chatswood. It was originally constructed by the PWD in 1911 and then transferred to the Board in 1913.
* W.O. 39014 - Extending from the western side of Archer Street to the southern side of Albert Street, Chatswood. It was constructed by the Board in 1966.
* Government Contract 1006 - The section from Albert Street to Victor Street, Chatswood, was constructed by the PWD in 1911 and transferred to the Board in 1913.
* Council Contract - The section from Victor Street to the termination point in Orchard Road, Chatswood was constructed by council. The construction date is unknown.

The numerous branches and amplifications which have been added to the system were done between 1911 and 1968 by the PWD, Water Board and Council.

Assessment of significance

SHR Criteria a)
[Historical significance]
The Willoughby - Chatswood stormwater system represents one of the early examples where a stormwater and sewerage system were built separately of each other within the same catchment area. Prior to the commencement of this stormwater system (1911) the general practice was to build combined sewers first and then build a separate sewer system at a later date.
SHR Criteria c)
[Aesthetic significance]
N/A
SHR Criteria d)
[Social significance]
Socially significant as it represents the development of a stormwater drainage system in the Lower North Shore area. The system helped improve public health and reduce illness in the area and is likely to be valued by the general community for the function it serves.
SHR Criteria e)
[Research potential]
The channel was progressively built throughout the 20th century, commencing in 1911 and being completed in 1968. Consequently it provides evidence of the change in drainage construction techniques throughout this era.
SHR Criteria f)
[Rarity]
The stormwater channel by itself is not particularly rare. The fabric is typical of stormwater channels built during the early 20th century.
SHR Criteria g)
[Representativeness]
Representative of one of the first times a stormwater and sewerage system were built separately within the same catchment area.
Integrity/Intactness: The channel is considerably intact.
Assessment criteria: Items are assessed against the PDF State Heritage Register (SHR) Criteria to determine the level of significance. Refer to the Listings below for the level of statutory protection.
