Joseph J. Brennan, 62

Joseph John Brennan, who had been the superintendent of the East Hampton Town wastewater treatment plant from 1986 to 2001, died at home on Montauk Avenue in Sag Harbor on Saturday. He was 62 and had been ill for about a year and a half, his wife, East Hampton Town Clerk Carole Brennan, said.

Mr. Brennan, who was known to friends for much of his life as Jody, was born at Southampton Hospital on May 26, 1952. His parents were Joseph W. Brennan and the former Maria Wobst. He grew up in a house on Lumber Lane in Bridgehampton and graduated from the public school there.

He married Carole Ann Diederiks of Sag Harbor on Feb. 5, 1972. At the time, Mr. Brennan worked at the B.P. service station in Bridgehampton.

Mr. Brennan’s first job in the waste treatment field was at Sag Harbor’s treatment plant. From there, he went to work for East Hampton Town, while continuing to live in Sag Harbor.

Ms. Brennan said that her husband’s greatest interests were his children and four grandchildren.

He was a volunteer firefighter with the Sag Harbor Fire Department for about 25 years, Ms. Brennan said, and a member of its ambulance corps for more than 20 years.

In addition to Ms. Brennan, he is survived by his children, Rachel M. Lucyk of Sag Harbor and Matthew J. Brennan of Springs, his grandchildren, and a brother, Thomas M. Brennan of Wainscott. His parents died before him.

Visiting hours for Mr. Brennan were held on Sunday at the Yardley and Pino Funeral Home in Sag Harbor. His funeral was Monday at St. Andrew’s Catholic Church in Sag Harbor.
