A Geotechnical Guide for Pump Stations Projects in the Sydney Region

This paper provides a guide to geotechnical require ments at the investigation, design and construction stages for typical sewage pump station projects in the Sydney region. This guide is based on experienced gained from over 230 pump station upgrades carried out as part of the SewerFix Pump Station Project (SewerFix) between 2001 and 2004.

Large, multi -site projects such as SewerFix provide an excellent opportunity to develop a systematic method of collecting and calculating geotechnical information. It is anticipated that the protocols developed during the project may be applied to other similar programs with a view to improved efficiency.

The paper also present the benefits of conducting such a project under an alliance contract arrangement, which facilitates continual geotechnical input throughout the lifecycle of each pumping station and the project as a whole.
