www.colchestervt.gov  Sewer service laterals are projected to cost $1.7 million.  If funded through the CWSRF, the Town must

  • wn and operate the

laterals.  Ownership places a significant and unusual burden on the utility.  It is unreasonable to place the responsibility for funding and construction

  • f the laterals on individual

property owners.  With voter approval, use $1.7 million in LOT funds to construct service laterals.
