Roberts Reservoir project

Aqwest is undertaking slope stability works to one of its key water storage facilities at the Roberts Crescent Reservoir.

The works to construct a more gradual slope gradient, will also result in easier and better access points to be created to the site and enable Aqwest to deliver the most cost-effective and efficient planned maintenance of an important asset.

The works will take place on land next to the reservoir after Aqwest purchased the property, the former GWN7 site, in June 2021 and removed the buildings in April 2022.

The slope will take up part of the land, with an accessway and new planting of trees and shrubs making up the majority of the property, creating a greatly improved amenity on Roberts Crescent.

During removal of the building, materials were recycled and repurposed where possible and memorabilia from the GWN7 building was donated to the Bunbury Museum for display. A plaque constructed from some of the building material recycled during the works will commemorate the site of the former GWN7 building.

Construction of a more gradual slope gradient will start in April 2023 and finish in September 2023.

Improvements to Roberts Reservoir

In recent years Aqwest has undertaken a major slope stability improvements at the Roberts Crescent Reservoir.

Improvements included revegetating the banks with native plant species, construction of  a 2m high limestone block retaining wall at the top of the slope and installation of a palisade security fence on the wall.

The works included adding 5250m3 of fill to the embankment, laying 4104 limestone retaining blocks and planting 72,016 plants.

“Not only are the banks more stable and less prone to erosion, but additional vegetation and trees will greatly improve the amenity of the area for the local community,” said Aqwest General Manager Water Services Cristiano Carvalho.
