Sewer Main Upgrade for Victoria Park Development, Zetland
Project: Sydney Water Corporation
Project: Upgrade of sewer infrastructure for the Victoria Park Development Zetland
This project involved the upsizing of an existing Sydney Water sewer main using pipebursting. The objective of the project was to increase the capacity of the sewer main with upsized pipe to alleviate potential flow problems to meet the future requirements of the Victoria Park Development. The site for the Victoria Park Development was the former Navy Supply Centre on South Dowling Street, Zetland. The 25 hectare site has road frontages to South Dowling Street, O’Dea Avenue, Joynton Avenue and Link Road in the City of Sydney Council area. Landcom acquired the site in order to transform it into a high quality living and working environment.
Downer PipeTech has been providing pipebursting for the trenchless renewal of water, sewer, stormwater and industrial pipelines in Australia for over 18 years. Pipebursting is one of the few trenchless technologies that provides a completely new pipe without being infl uenced by host pipe conditions. Pipebursting typically includes renewal of all services and connections, ensuring a service life consistent with a new pipe installation upon completion. One of the advantages of pipebursting is the ability to upsize the host pipe. The degree of upsize is primarily limited by surrounding soil conditions, depth and proximity of other services. Besides Sydney Water, work has been performed for other clients including: Wagga Wagga City Council, Toowoomba Council and Wingecarribee Shire Council.
The objective of the project was the upsize replacement of Sydney Water’s southern sewer main to provide the necessary sewer infrastructure for the Landcom Development Park. To achieve this a number of requirements were considered:
- Compliance with Sydney Water technical requirements
- Ascertain the most economical and practical route for the sewer
- Make available the sewer infrastructure within time constraints
