Project Description:

Construction and commissioning of a 3 Megalitre reservoir pump station and 400m long rising main, including conduit runs, electrical installation and hypochlorite dosing facility. Associated civil works included construction of an access road and various concrete works including a valve pit and retaining walls. Then commission and cut into existing mains.

Complex Challenges:

The construction site was extremely steep, with restricted access for construction equipment and very limited space for fabrication, assembly or storage of construction components. The reservoir was constructed using steel plates, fabricated in an off-site workshop to the correct size and shape. The plates were transported to the site to be erected and welded piece by piece, followed by a multi-step painting process under stringent quality control conditions. The result was a solid, durable, hydrostatic steel reservoir for potable water storage.
