Wastewater Pipeline Renewal Projects in Cheviot and Hanmer Springs

The projects are in Cheviot and Hanmer Springs, North Canterbury. The proposed Cheviot wastewater renewal installation runs across private land, starting in paddocks next to Reeves Street then follows Fergus Street (Paper Road) finishing at Seddon Street. The proposed Hanmer Springs wastewater renewal runs down SH7A then into the Hanmer Springs wastewater treatment ponds.

This contract will run as separable portions for the two projects, the Cheviot project needs to be delivered first. The proposed Cheviot pipeline consists of approximately 420 metres of DN225 unplasticised polyvinyl chloride (uPVC) wastewater main and 230m of DN900 concrete storage pipe.

The proposed Hanmer Springs pipeline consists of approximately 86 metres of DN475 unplasticised polyvinyl chloride (uPVC) and DN1200 concrete storage pipes. Both projects consist of wastewater manholes and its associated connections. The Contractor is to supply and install all pipes, manholes, fittings, and connections.

Also, the proposed wastewater alignments run approximately parallel with parts of the existing wastewater main; caution will be required to maintain separation from this live gravity pipe, and also any associated fittings and structures.

These existing pipes will also need to remain �live� during construction to maintain services to local residential and commercial properties and shall be abandoned concurrently with the connection of the new mains to the existing network.
