The Central Otago District Council is considering a decision on Wednesday regarding the disposal of growing volumes of treated wastewater sludge. Staff have warned that Cromwell's ponds urgently require de-sludging and that geobags containing thousands of cubic metres of dried sludge from a decade ago must be moved.NZ HeraldRNZ

While an original recommendation suggested dumping the waste on land near Lauder using an existing non-notified consent, staff have since recommended sending the sludge to Winton landfill instead. This change follows concerns that the Lauder site might only be able to accommodate half of the sludge from Cromwell.NZ HeraldRNZ

The updated recommendation to use the Winton landfill brings the total estimated cost for de-sludging and transport to more than $3 million, including contingencies. This is significantly higher than the $1.6 million estimated for the Winton landfill option alone, which was expected to save $600,000 compared to the original plan.NZ HeraldRNZ

Federated Farmers Otago president Anna Gillespie stated that the proposal has angered local farmers who have worked to improve water quality. Gillespie said, "It's absolutely staggering that the council is even discussing this after the recent outcry over Wānaka trucking its treated excrement to a Lauder farm".NZ HeraldRNZ
