The Invercargill City Council is inviting tenderers for the supply of all labour, materials and plant necessary for the renewal of approximately 650m of stormwater main and all associated works in Korimako Avenue, Otatara. The Contract shall also include the renewal of all associated laterals, manhole structures, fittings fixtures and connections.

Existing stormwater mains on either side of the road are to be replaced by a 450mm Class 2 Concrete main on the south side of the road. Existing drainage pipes are to be abandoned or removed depending on the trenching methodology. Lateral locations are to be determined through potholing as CCTV is not possible due to root intrusion along the pipe length.
