Section 89-L. Municipal water systems

1. For the purposes of this section,
  and for the purposes of any jurisdiction conferred by it upon the public
  service commission, a municipality  is  one  which  owns,  maintains  or
  operates,  or  proposes  to own, maintain or operate, a water system, or
  which sells, furnishes or distributes, or proposes to sell,  furnish  or
  distribute,  water  for  domestic,  commercial  or  public uses, whether
  provided by its own system or the system of a water-works corporation or
  another municipality. As so limited, the  term  "municipality"  for  the
  purposes  of  this  section,  means  a  city,  town,  village  or public
  district; and a "public district," as here used, is a district or  other
  territorial  division,  whether  incorporated  or not, whose affairs are
  managed by any officer or officers, person or persons, elected by voters
  or taxpayers or appointed by a public officer or officers, and includes,
  without excluding others, a water district, water supply district and  a
  fire  district.  The other provisions of this chapter shall not apply to
  such a municipality, nor to its said business of owning, maintaining  or
  operating  a  water  system  or  of  selling, furnishing or distributing
  water, except such provisions as are applied by this section by  express
  reference.  The  jurisdiction  of  the  public  service commission, with
  respect to such a municipality or its said business, is that,  and  only
  that, provided for in this section.
    2.   Each  such  municipality  shall  file  with  the  public  service
  commission a copy of the  annual  report  of  its  division,  bureau  or
  department of water.
