Ross Creek restora­tion takes shape

THE Dunedin City Coun­cil’s restora­tion of the Ross Creek Reser­voir dam took an­other sig­nif­i­cant step to­wards com­ple­tion yes­ter­day as con­crete pan­els for a wave wall were in­stalled along the dam’s crest.

The 23 pan­els were be­ing added dur­ing the next few days to stop waves breach­ing the crest of the dam in windy weather, coun­cil en­gi­neer­ing project man­ager Camilla Ben­nett said.

Each panel was 5m long and 1.9m high, and weighed 6.8 tonnes.

Once the wall was in­stalled, the top of the dam would be com­pleted and a foot­path built, she said.

The work was part of an $8.6 mil­lion re­fur­bish­ment of the dam, which in­cluded re­build­ing and strength­en­ing the dam face, widen­ ing the spill­way, rais­ing and widen­ing the dam crest and build­ing a new siphon pipe to take wa­ter out of the reser­voir.

The project would al­low the dam to be used as an ex­tra wa­ter sup­ply for Dunedin.

Ms Ben­nett said the project was run­ning smoothly but had not been with­out its chal­lenges.

‘‘Along the way we’ve en­coun­tered a lot of un­fore­seen el­e­ments such as ground con­di­tions, un­fore­seen struc­tural con­di­tions, we’ve had to tend with ar­chae­o­log­i­cal finds and, of course, the weather which hasn’t al­ways been kind to us.’’

The chal­lenges meant the cost of the project had in­creased from $6.6 mil­lion to $8.6 mil­lion, but work was ex­pected to be com­pleted by Au­gust.
