Page / Weetangera Stormwater Improvements

description

Indesco provided design services for stormwater improvements for Page / Weetangera, which was a design refresh of a previous PSP study undertaken by Bill Guy and Partners over 10 years earlier.

The overall catchment of the system spans across two suburbs, Page and Weetangera. Major flooding issues, especially excessive overland flow and ponding, have led to a number of stormwater augmentation works in the area.

The upgrade was sufficiently extensive such that it needed to be broken up into three stages at a total cost of $6 million [2000]. The design involved the use of large pipes and reinforced concrete box culverts and drainage structures to convey 100-year ARI events. Engineering design details required that stormwater conduits be laid among existing services and mature trees.
