and are hereby empowered to levy annually a special sewerage tax suffi-
cient to pay such bonds as may be issued, and the interest thereon, as the
said bonds and interest or coupons may severally mature, as herein pro-

groups of contiguous town lots, under one ownership, vacant or occupied,
which may be served by the said sewerage system, in such proportion of

lots bear to the number of front feet in all lots which may be served by
the sewer installed, or to be installed, by the expenditure of the funds,
realized from the sale of said bonds; provided, however, that where a
corner lot fronts or abuts on two streets, both containing sewers, requires
but one service, the front feet shall be computed for the purpose of this-
assessment as one-half of the total number of front feet in such corner
lot bordering on both streets. The costs of maintenance shall be assessed
equally against the owners of the houses or other structures served by the
sewer, and shall be due and payable bi-monthly, in advance. And the said
special tax and all assessments for the maintenance and service charges
shall be liens upon the assessable property of said town against which
they are levied. The said taxes or assessments shall be collected in like
manner as other taxes are levied in the said town are collected, and when
collected shall be applied as hereinbefore and hereinafter provided; said
bonds and coupons, when so issued, shall be non-contestable for any cause
whatsoever, and the said bonds and coupons so issued, when redeemed,
shall be cancelled immediately, and it shall be the duty of the said Mayor
and council of Garrett Park to cancel the same.
