At last call the Pou project had ballooned from its original budget of $35,000 to $92,000 and that does not include the amount frozen which was intended to be used for smaller pou at four secondary approaches to town.
It may also not be the final figure as the $92,000 was based on projected and not actual costs.
Mr Borren said the results of the review will be shared with all councillors and that in the meantime money for completing the project has been frozen.
Councillor David Holmes said while councillors were getting a lot of " kickbacks" over the Pou he is having to answer many questions on the Homebush scheme.
In March, even though rainfall was relatively light, an area set aside for receiving wastewater by border dykes had flooded.
From his property he could overlook paddocks of yellowing grass as they were already inundated with water, he said.
Mr Holmes referred to the departure of special projects manager Ian Steer who, he said, had resigned and left "in three days".
"We have had no explanation why he left," Mr Holmes said.
