The error is likely to be corrected at the council's next meeting.
On June 14, the council adopted a resolution that included its stormwater targeted rates fixed charges.
Those charges were incorrect for Balclutha, Clinton, Kaitangata, Kaka Point, Lawrence, Milton, Owaka and Tapanui areas.
In a new agenda item for this week's meeting, the information has been corrected and supplied to the council for consideration.
The council has set a uniform targeted stormwater rate for each separately used or inhabited part of a rating unit (SUIP) that was either connected to a scheme or for which a connection was available.
The recommendation will increase the recently adopted charges for Balclutha from $65.85 to $67.20, Clinton from $63.65 to $65.60, Kaitangata from $52.60 to $57.25, Kaka Point from $50.30 to $55.50, Lawrence from $61.25 to $63.80, Owaka from $48.10 to $53.90 and Tapanui from $65.20 to $66.70; Milton drops from $95.45 to $89.45.
Remaining rural areas are recommended to be set at $35.55.
The council will discuss the recommendation and change tomorrow.
