HAUPPAUGE - Suffolk residents may soon have to pay a new annual surcharge for using water.

The county is planning to hold a public referendum in November that would ask voters to approve a water quality protection fee.

The money would go toward reducing nitrogen pollution, upgrading cesspools and connecting homes to sewers in an effort to keep Long Island's groundwater and waterways clean.

Officials estimate that a typical household with a family of four would shell out about $73 extra per year. The surcharge would apply to those with public water.
