Section 120-Z. Sewer hook-ups by private contractors

Whenever a contractor
  retained or hired to connect or hook-up a private property with a  sewer
  system in a city, town or village, requires that all or a portion of the
  cost  of such connection for hook-up be paid in advance of completion of
  the same, the amount of such payment shall be held by such contractor in
  an escrow account until completion of such work, if the  city,  town  or
  village  in which the work is to be done so requires. Such city, town or
  village may by local law or ordinance regulate such escrow payments  and
  the enforcement thereof.
