Attempts to clear sludge from one of three ponds at the Homebush sewage treatment plant are proving more costly and difficult than expected - and the councillor regarded as the project's watchdog is not happy about it.
David Holmes said, at a meeting last week, the truth is "council hasn't a clue what clearing sludge from pond 3 is going to cost".
His remarks came on the back of a report from finance manager David Paris alerting councillors loan funding needed for the Homebush project this financial year was projected as being close to $2 million, up from the $1.25m that had been allocated.
Project delays from the previous year had resulted in a cost carryover and there had been extra costs relating to sludge and pond 3.
In a submission to the 10 year Long Term Plan, which runs through to 2025, officers had signalled earmarking an extra $500,000 to be spread over three years to "progressively deal" with sludge in the pond.
