Reservoir Canal Pump Station Inlet Bay Upgrade

Major works included:

• Design of temporary works and the installation of a clay cofferdam and dewatering to bund off and control the canal.

• Demolition of the existing pump station componentry to allow for new concrete and metal work.

• Excavation and subgrade improvements including 14m timber piles with concrete pile cap foundations.

• The new pump station inlet comprised of precast concrete walls placed on the concrete pile cap foundations. The panels were tied in with a concrete floor and in-situ stitch joints to the existing structure.

• The design and construct for a precast hollowcore deck which included an in-situ concrete topping slab. These items required a PS1 and PS3.

• The removal and replacement of all mechanical componentry with the replacement of large sluice gates.

• Site reinstatement which included retaining walls, timber steps and fences, metal access tracks and grassing.

This project was completed in May 2018.
