BALTIMORE (WBFF) - Baltimore's public works department is apologizing to 566 customers who got severely inflated water bills by accident.
Of the 566 erroneous bills that went out, most were for more than $50,000, said the public works department in a news release Thursday.
The department stopped all bills until the flaw is fixed, saying "this delay should be minor and will not result in larger bills."
The accidental over-billing "is not acceptable, and I am insisting we strengthen our billing safeguards,” said DPW Director Rudolph S. Chow in a statement. “I have directed staff to send letters to all those customers affected by this error, and to make direct contact in every case possible.
The mistake happened after the department upgraded some software over the weekend.
Despite extensive testing, the Customer Support and Services Division learned Wednesday about the accidental bills, according to the news release.
Chow added that "customers affected by this error should know that we will make the necessary corrections and not allow this to negatively impact their account. I apologize to these customers for the erroneous bills and want everyone to know I take the credibility of our metering and billing system very seriously. Our customers deserve nothing less.”
