The general manager of the Portland Water District has resigned after just under two years on the job.

Seth Garrison was appointed manager in October 2022 and resigned from his position on Aug. 26 after going on an extended leave this spring to care for his daughter, according to one Portland Water District board member.

The Portland Water District supplies water to Greater Portland and is run by an elected board with representatives from Portland, Scarborough, Cape Elizabeth, Windham, Gorham, Cumberland, Westbrook, Raymond and Falmouth.

At the board’s meeting in late August, members authorized a separation agreement to finalize Garrison’s departure and appointed Chris Crovo as interim manager. But the exact details of the agreement were not discussed, and staff members did not respond to messages Wednesday asking for a copy of it. The board also agreed to hire a consultant to recruit a new general manager.

Guy Cote, who represents Westbrook on the board, said in a phone interview Wednesday that Garrison went on leave and ultimately resigned because his daughter is sick and Garrison has been spending time with her in the hospital.

“Seth did a very good job as manager. The last six months have been very difficult for him and his family,” Cote said.

He said Garrison resigned when it became clear he wouldn’t be able to commit the necessary time to the district given his daughter’s illness.

In the meantime, Cote said he is confident that Crovo will do a good job leading the district.

“The district is certainly in good hands,” he said.

Garrison did not respond to messages Wednesday asking about his departure.

According to an announcement of his hire in 2022, Garrison spent more than two decades working with water and wastewater systems, including the Pittsburgh Water and Sewer Authority, Boston Water and Sewer Commission, and New York City Department of Environmental Protection. He also served on the district board, representing Scarborough, for nine years.

When reached by phone, board members Leroy Crockett and Daniel Willett said they had no comment on the circumstances surrounding Garrison’s departure or on the district’s plans for hiring a replacement. None of the nine other board members returned phone calls asking about Garrison’s departure.
