This Contract is for the supply of all labour, materials and plant necessary for the renewal of both the Stormwater and the Watermain on Tay Street, Invercargill, between Mary Street and Jackson Street.
The Stormwater Pipe will be on a new alignment on the opposite side of the street to the existing main. It will be made from 176m of DN600 Class 2 Concrete Rubber Ring Jointed Pipe and 16m of DN375 uPVC Pipe. This will avoid the demolition of the 157m of pre-1900 Brickmain Pipe that will be abandoned with flowable fill. Six (6) Manholes are proposed, ranging from 2.3m to 3.7m tall. Two of them will be replacing existing manholes, one of them being replaced is a square brick structure of an undetermined age.
The watermain will be replaced like-for-like to remove the 1930’s cast iron watermain that was rehabilitated in 2006, and be replaced by 176m of DN180 PE100 PN12.5 Pipe. 28m of DN125 and 21m of DN63 Pipe will be required for link-ins, with 16m of Asbestos Cement Pipe to be appropriately removed and disposed of.
Works are to be completed before the Waka Kotahi/NZTA holiday moratorium in December 2026, ahead of their resurfacing works in summer. Both alignments are proposed to be replaced using open-trench methodology.
The Contract shall also include the renewal of all associated laterals, manhole structures, valves, hydrants, fittings fixtures and connections.
