Candidates Dr Ursula Stephens (Labor), Dr Saan Ecker (Greens) and Andy Young (Shooters, Fishers and Farmers) said they would support an investigation while at a meet-the-candidates event in the village, last Thursday evening.

Dr Stephens told residents "the process stinks" and that there was no logic to the council’s proposal. She said she had spoken to the Shadow Minister for Local Government, Peter Primrose, who believed the council's approach wouldn't work and committed to undertaking an investigation through the Office of Local Government.

The council has been investigating the need for a sewerage system in Gundaroo since 2016, to support future land divisions as the village expands. However, resident group Gundaroo Against a Sewerage Plant maintains it does not want a sewerage system in the village and that the village's lack of water could be cause for concern.

The group's chair, Abram Hays, said he was pleased to see the candidates support an investigation and would be interested in the outcomes of an independent inquiry.

However, the council's director of engineering, Stan Robb, said the council had never resolved to install sewerage in the village of Gundaroo and was simply going through a preliminary investigation.

In response to community concerns, the council has been exploring the option of a staged construction of a sewerage system. It would start in Gundaroo's main street and allow residents to connect if and when they wanted to.

Mr Robb said the results of the investigation would be provided to residents at a community meeting at the Gundaroo Soldiers Memorial Hall on Wednesday, March 20, from 7.30pm.

Liberal Party candidate Wendy Tuckerman said that, based on the information she had, she thought the council's plans for a sewerage system in the village "wouldn't be feasible", but reminded residents to keep in mind that a decision was yet to be made.
