By Associated Press 12:13pm, October 14, 2013The New Castle County auditor says the county's overbilling of Artesian Water customers on their sewer bills was worse than originally estimated.
The News Journal reports county Chief Financial Officer Mike Coupe now estimates that the errors in bills totaled $675,000. That's higher than the $500,000 estimate Auditor Bob Wasserbach gave officials in July.
The problem started when Artesian switched from a quarterly to a monthly billing system last year. Sewer bills are calculated based on water consumption.
Coupe says 21,347 residential customers were overbilled and another 6,957 customers were underbilled for a total of $218,000. About 20,000 customers' bills were accurate.
Wasserbach said in July that county officials knew about the problem in December, but decided to only take action if they got complaints.
