BILL PEARSON Edgecomb town hall. File photo Davis Island residents were notified last week when a proposed two-tiered Wiscasset Water District rate increase would occur. And on May 3, Superintendent Chris Cossette explained why. Cossette met with Edgecomb selectmen about the proposed increase and discussed other issues floating around regional water issues. On July 1, Edgecomb (Davis Island) ratepayers will see a 19% rate increase which covers additional hydrant rental fees. Cossette reported the annual hydrant rental rate would increase to $1,954.31 or $234 more. In 2022, the second rate increase would bring the fee to $2,579. Davis Island is the only portion of Edgecomb the Wiscasset Water District serves.
