A former Passaic Valley Sewerage Commission official has pleaded guilty to official misconduct charges.

Kevin Keogh of Roseland entered his plea Thursday before a superior court judge in Paterson.

The 46-year-old Keogh was the former superintendent for special services at the authority.

He pleaded guilty to conspiracy and official misconduct charges in a scheme prosecutors say involved ordering employees to perform personal work for him, such as repairs or improvements on his home, while on company time.

Keogh was arrested in Feb. 2011, along with two other former managers at the sewerage authority. All three were fired.

More than 100 employees of the commission have been fired amid allegations of nepotism, mismanagement and excessive salaries.

The PVSC provides wastewater treatment service to 48 communities in northern New Jersey.
