A major year-long project to repair Dunedin's Ross Creek
Reservoir is expected to begin in October.
The reservoir is to receive a multimillion-dollar
restoration, including reconstruction of its earth dam, to
make it a functional reservoir again.
The work is part of a Dunedin City Council project to ensure
there is a a back-up water supply for the city in an
Council water and waste services asset and commercial manager
Tom Osborn said an application for a building consent for the
dam work was lodged with the Otago Regional Council and,
subject to that being approved, tenders were being sought for
The work included construction of new buttresses at one end
of the dam, widening its crest, strengthening it to deal with
earthquakes and floods, modifying the spillway chute so it
could discharge more water and closing old off-takes and
building new ones, as well as various minor repairs and
Once the consent was in and the tender awarded, the council
planned to put up an information board at the site to show
the public the design, contractors and what the finished
works would look like. The dam earthworks were estimated to
cost about $2.2 million.
At the same time, a new pump station would be built in the
old water treatment plant buildings at Ross Creek, as well as
a new pipeline from the reservoir to Mt Grand, he said.
