Mark Berger was elected the newest Great Neck Water Pollution Control District commissioner Tuesday night, defeating Robert “Bob” Welner.

Mark Sauvigne and Ken Weigan, incumbent commissioners for the Manhasset-Lakeville Fire and Water District and Manhasset Park District also secured re-election Tuesday in their uncontested races.

William Costigan was re-elected to another term as Roslyn Water District Commissioner.

Berger, who was endorsed by the outgoing commissioner Jerry Landsberg, secured the win with 347 out of 573 votes, enough for 60.5%. Welner trailed behind by 121 votes, receiving 226 votes.

Berger has been a resident of Great Neck since 2010. He is a public interest attorney, currently supervising a team of 50 lawyers, support staff and paralegals.

He previously told Blank Slate Media the three reasons that motivated his bid for Great Neck’s water commissioner: a desire to give back to his community, his passion for environmental protection and his legal and managerial experience.

Berger and Welner raced to fill the seat to be left by Landsberg, who retired from the board after 16 years of service.

Manhasset-Lakeville Fire and Water District Commissioner Mark Sauvigne won another three-year term Tuesday night.

Sauvigne, who ran uncontested, had 348 total votes out of 361 cast. The other 13 were for write-in candidates, according to the district. 

He will serve alongside Commissioners Steve Flynn and Brian Morris, who is up for re-election next year. 

The Manhasset-Lakeville Fire and Water District takes in all of Manhasset except for Plandome, half of Great Neck and some of northern New Hyde Park.

Though the board oversees both the fire and water districts, which cover the same geographic area, the two are technically independent of each other.

The fire district has a $9.7 million budget next year and the water district has a $11.2 million budget, according to the North Hempstead 2024 budget.

The Manhasset-Lakeville Water District serves approximately 45,000 customers who use 7.4 million gallons of water a day within the service area of 10.2 square miles, according to the water district’s website.

Eighteen wells at 13 locations provide water to Manhasset and portions of Great Neck and North New Hyde Park. 

Sauvigne, who was first elected in 2014, also serves as Manhasset Park District treasurer alongside Weigand.

District residents in October voted to approve a $10 million bond to build a new ambulance unit building in Lake Success.

The vote ended a years-long search to move the 40-person ambulance unit out of the department’s Company No. 3 firehouse in Great Neck, where it shared a space since 1988.

Weigand, a second-generation Manhasset resident, secured a fourth three-year term as park commissioner Tuesday with 106 out of the 113 total votes cast. He will continue to serve alongside Sauvigne and David Paterson.

The park district is responsible for running the area’s parking lots and maintaining parks like Patriot’s Park and the World War II Memorial on Plandome Road, among others.

Its budget for next year is $1.7 million, according to the town’s budget.

Roslyn Water District Commissioner William Costigan was re-elected to another term Tuesday night. 

Costigan, a Roslyn community member for 42 years who owns a printing and binding company, ran unopposed and won with 28 votes. He will continue to serve alongside Michael Kosinski and Sanford Klein. 

Costigan has served as commissioner since 2002 and acts as the board’s treasurer. The incumbent previously said to Blank Slate Media that he is running to continue water conservation, ensuring the district’s fiscal responsibility and providing high-quality water to residents. 

“Most of us make the assumption that you turn on the tap and the water is there, but no one really delves into what it takes to get the water from approximately 400 feet underground to the tap and have it available for you seven days a week, 24 hours a day, 365 days a year,” Costigan said to Blank Slate Media.

The Roslyn Water District services the Villages of Roslyn, Roslyn Estates and East Hills, as well as portions of Roslyn Heights, Roslyn Harbor, Flower Hill, North Hills, Greenvale, Albertson, Glenwood Landing and Port Washington.

It serves 5,804 residential and commercial customers throughout the 5.1-square-mile area of its district.

The Roslyn Water District was established in 1910, making it one of the oldest public water providers on Long Island.
