He was carrying their water.
Mayoral candidate Bill de Blasio made it a “high priority” to help political pal Dan Cantor of the left-leaning Working Families Party reduce a water bill of nearly $9,000, The Post has learned.
A review of de Blasio’s archives from his eight years as a member of the City Council found he his staff went to great lengths seven years ago to help Cantor, a constituent at the time living in Park Slope.
The political party chief first contacted de Blasio’s office on Feb. 15, 2006 to complain about the enormous water charge.
A week later de Blasio penned a letter to Environmental Protection Commissioner Emily Lloyd to request a reduction.
“After reviewing their situation, it appears to me that they were erroneously charged $8,989,” he wrote. “I would greatly appreciate it if you would investigate this matter and help us resolve it as quickly as possible.”
The correspondence was followed by a series of back-and-forth e-mails and phone calls involving Cantor, his wife Laura Markham, de Blasio and his staff and DEP employees.
In one message Cantor even joked that fixing the bill would save his marriage.
“Can’t believe I’m calling you about this but I was wondering if you had a chance to look at that DEP water bill problem I sent to you. Would do wonders for my marriage if you could help me here so if you need me to resend it just let me know,” Cantor said.
De Blasio responded quickly.
“Have u worked on this Cantor issue below? If not, contact him and get details – I have not seen paperwork. High priority,” he instructed a staffer.
The bill was eventually reduced to $1,120 in June 2006.
De Blasio also intervened that same year to help nephew of Rep. Yvette Clarke (D-Brooklyn) get into his school of choice, M.S. 51.
It was previously reported that de Blasio also intervened when constituents asked for help to dismiss parking and other summonses.
A spokesman for the Democratic mayoral nominee said he was acting as an elected official responding to the needs of constituents in both instances.
“Part of his job as Council member was to help people in his community having problems with the city’s bureaucracy,” said spokesman Dan Levitan.
De Blasio helped found the Working Families Party and the organization’s backed him in the 2009 Public Advocate’s race — but not in this year’s Democratic primary for mayor because of a split in the ranks.
Meanwhile, de Blasio’s fundraising effort got a big boost when Hillary Clinton announced she would be sponsoring an event on his behalf next month.
