The Whakatāne District Council has approved $260,000 of additional work on the water supply
systems serving Ōhope and elevated residential areas of Whakatāne, to reduce the potential for
future supply interruptions.
The work to improve the resilience of the supply network will be undertaken in conjunction with the
renewal of the water main between the Ōtarawairere reservoir and the Ōhope Road/Pohutukawa
Avenue intersection. The work along Ōhope Road is expected to be completed in December, ahead
of the busy holiday season. Further work to install and commission new valves at the reservoir will
follow in early-2019.
In a report received by the Council’s Projects and Services Committee last week, Capital Projects
Manager Jim Finlay said that as a result of the water main project, a number of supply network
improvement opportunities had been identified. These included a revised design and valve system
which would allow the Ōtarawairere reservoir to be bypassed, if necessary, with Ōhope consumers
supplied directly from the Whakatāne scheme; and the elevated residential areas above Whakatāne
to be supplied from the Ōhope scheme.
“The improved design would avoid potential, lengthy water supply disruptions, such as the outage
experienced in Ōhope during the April 2017 storm, when the supply line at the reservoir was
severed,” Mr Finlay said.
Other design limitations highlighted by the water main replacement work will also be remedied,
including the relocation of valves and valve connections at the reservoir, to make future
maintenance work on the system easier and more economical to accomplish.
Committee members adopted a recommendation that the extended scope of the water main project
be approved, with the additional cost to be met within the Council’s existing 2018/19 Three Waters
renewal and capital budgets.
