Twizel land eyed for sewerage upgrade
The Mackenzie District Council is eyeing up 25 hectares of land near Twizel as part of a plan to upgrade the town's sewerage system.
The purchase would see the town's waste capacity increase from 1500 cubic metres to an expected 1800 cubic metres of waste a day, using a ground piped disposal system.
Hydraulic conductivity tests were undertaken at the site late last year to determine the soakage of the subsoils, which defined the land area required for current demand and to future-proof the existing facility.
Test results confirmed 2.3ha was required to dispose of the expected 1800 cubic metres while a rapid infiltration system would fit within the 150m odour buffer.
Council asset manager Bernie Harr said the total area required for the upgrade would be 21.52ha, with a further 25.38ha to be protected by covenant and a no-build zone, to extend the odour buffer out to 300 metres.
Mr Harr and chief executive Wayne Barnett will meet the land owner soon to continue negotiations to acquire the land.
Mr Harr would not comment further on negotiations, saying the matter was commercially sensitive.
He did outline expected costs for the "physical work".
"A feel for the cost to go forward is $750,000 for the physical work."
The project could be several years away and was subject to an Environment Canterbury consent lodged in 2010.
