“A Betterton couple is suing the town in a dispute over water bills that could set a precedent if the judge rules on their behalf. In a suit filed in District Court February 6, Jean and John McDougall of Bayside Boulevard have taken the town to court for $768 plus interest and legal fees over their bills of September and December 2008. According to the complaint, the McDougalls paid the amount “”in protest.”” They now seek to have it refunded on grounds the water did not go into the sewer system and therefore should not be billed.”
