David Alexander, 54, admitted to lying to the FBI about his role in the botched launch of an LADWP computerized billing system.
The failed system led to many customers receiving wildly inflated bills.
Alexander has also been ordered to pay a fine of $50,000 dollars.
Two months ago, former LADWP top executive David Wright was sentenced to six years in federal prison for his participation in the bribery case -- accepting payments from a lawyer in exchange for helping the attorney obtain a $30 million no-bid contract for the lawyer's company, the U.S. Attorney's Office said.
