A New York Post analysis of the city’s budget shows that plumbers were the top earners for overtime pay.

Based on recent payroll data, 25 plumbers working for the city made more than $200,000, which was several times over their base salaries.

Out of the ten highest earning plumbers, nine of them were employed by the city’s Housing Authority. An NYC Housing Authority plumber made the highest earnings, receiving $315,158 in the 2017-2018 fiscal year. That included a base salary of $93,984, in addition to $213,634 in overtime.

The NYC Housing Authority defended the pay, saying: “With our aging infrastructure, we need our staff, especially skilled trades, to work 24 hours a day responding to emergencies and making repairs for our residents.”

Adam Andrzejewski, CEO of the government watchdog group OpenTheBooks.com, says the state of NYCHA house is forcing the agency to pay maintenance staff like plumbers way beyond their normal salary.

“City resources are being mismanaged and squandered because of a lack of proper staffing within the ranks of city agencies,” Andrzejewski said.

The average plumber in the United States, according to the Bureau of Labor Statistics made around $52,590 a year in 2017.
