Insitu Reinforced Concrete Reservoir
Whangaparaoa Road, Whangaparaoa Peninsula
Client: Rodney District Council
Designer: Harrison Grierson Consultants Ltd
Completed: December 2006
This project provides a larger and more secure water supply to the growing population along Whangaparaoa Peninsular, Rodney. It is an insitu, 28m diameter, 3,100 cubic metre concrete reservoir, partially buried in the hillside of Tindalls Hill. It has a precast concrete roof slab and the walls are 250mm thick insitu concrete.
The project also included upgrading all the incoming and outgoing network pipe lines along Whangaparaoa Road. All work was carried out whilst keeping the small existing reservoir in full operation.
Fort Projects elected to construct the reservoir insitu even though provision was made in the design to precast the wall elements. Earth embankments were also created as part of the project, these requiring controlled compaction techniques and careful sediment management.
