The Board reserves the right to refuse all petitions
for extensions of mains where the estimated water rents will not warrant
the cost of installation; however, the Board may determine that the
cost of extending mains may be borne wholly by the Village or wholly
by the owners of land benefited or abutting on streets on which said
work is done or partly at the expense of each. If such expense or
any part thereof is to be assessed upon adjoining land, the Board
may apportion it upon the land and assess the same as a whole or by
installments, said assessments to be made in accordance with § 11-1108
of the Village Law.
