OWASA said that it made an error in bills sent on Oct. 16 to 500, or about 2 percent, of its customers. Water use by the 500 non-residential customers in early October was incorrectly charged at the peak seasonal water rate of $7.09 instead of the new off-peak seasonal rate of $3.73, which went into effect on Oct. 1.
OWASA’s next bill for these customers will include a credit to correct the affected customers’ balances. The affected non-residential customers are in Carrboro, the Southern Village and downtown Chapel Hill.
Individually metered residential customers, who pay increasing block water-conservation rates, are not affected.
