Bay View Reservoir

Reservoir tank taking shape, Bay View Reservoir Project 2009.Planning Started: August 2006
Construction Started: May 2009
Completed: December 2009

Work on a project for increasing Bay View's water storage capacity began in mid-2006.

Preliminary work on feasibility, design, land and geotechnical surveys was completed in autumn 2008. A design and build contract was awarded in March 2009, and on-site construction began two months later.

The Franklin Road reservoir site at Bay View is located within the Heipipi Historic Reserve. Administered by the Department of Conservation (DOC), it is accessible only via a steep gravel track using 4WD vehicles.

Napier City Council applied to DOC for a concession to further develop the site and liaised with local iwi for approval to work within the historic reserve.

The reservoir plateau was previously occupied by two reservoir tanks - a rectangular tank constructed in around 1988 and a circular tank built several years earlier. Each tank had a capacity of 235 cubic metres, but the combined capacity had become inadequate because of growing residential development and increased commercial need in Bay View.

To provide additional storage capacity plus a degree of operational redundancy, the reservoir capacity needed to be doubled to about 1000 cubic metres.

After exploring options for providing additional storage tanks, it became clear that the plateau site was not big enough to provide the required storage without compromising access for service vehicles and DOC.

The solution was to replace the older circular tank with a new rectangular tank of sufficient capacity to maximise supply capability while minimising the proliferation of storage tanks in this sensitive environment.

The outcome is a precast concrete tank with a 900 cubic metre storage capacity. which will operate in tandem with the existing rectangular tank via interconnecting pipework.

The new tank is some five metres high, but set two metres below ground level. While the top can be seen from Highway 2 and Franklin Road, it has now been screened with trees, to minimise its visual impact.
