Queenstown Lakes District Council yesterday warned the public to take greater basic care with waste disposal to avoid unnecessary health risks.
Chief executive Adam Feeley said fat and grease from household and commercial businesses in Frankton and Kelvin Heights contributed to a blocked outlet and sewage overflow at Frankton.
"This is a completely avoidable problem that needs the community as a whole to think more carefully about what they're putting into their drains," Mr Feeley said.
The council is considering preventative maintenance of its sewerage systems, including inspections using closed circuit television cameras.
The council also intended to work with the Otago Regional Council to ensure anyone who caused wastewater system blockages was held to account, including liability for cleaning costs.
A 200-metre stretch of Frankton beach, which was closed by a sewage overflow at the weekend, has been reopened.
