Centennial Park Reservoir No. 1 was the site, in the early 1990s, of a public access program, instituted whilst the Reservoir was empty for refurbishment works, which attracted many thousands of members of the public, demonstrating a significant interest and value placed upon these structures by the public at large. Centennial Park Reservoir No. 1 is highly regarded by the public as represented by the National Trust of Australia (NSW), as evidenced by its identification in the National Trust Register.
