Wastewater improvements planned

Millions of dollars are set to be spent on wastewater infrastructure and cemeteries in the wider Taieri area.

The Dunedin City Council draft 10-year plan, released late last week, includes $44million in its  budget for the Green Island wastewater treatment plant upgrade.

The project aims to reconfigure the treatment process that will increase the plant capacity to receive additional flow from Kaikorai Valley.

The ageing wastewater network in the valley means rainwater has been entering 100-year-old earthenware pipes,  directing the wastewater and any extra that seeps in during wet weather through the old Caversham tunnel and on to the Tahuna wastewater treatment plant, via Surrey St in South Dunedin, one of the streets worst affected by the 2015 floods.

The plan said the upgrade, if approved by councillors, would provide increased capacity to respond to growth, improve public health and environmental outcomes, renew and replace assets and increase levels of service.

There is also $2million in the draft budget for extra cemetery space in Mosgiel.

The report said the project would provide further burial space to accommodate future demand in existing cemeteries  through the development of a new cemetery in the Mosgiel area. 

An initial feasibility study would be done to to assess the needs and possible options to provide further burial space  close  to Mosgiel.
