the said funds as required, or to use said funds or any
part thereof for any other purpose than for the payment
of the principal and interest on said bonds, is hereby de-
clared a misdemeanor and punishable as other misde-
meanors are punishable by Section 430U of this sub-title.
Likewise whenever any part of any sewerage or water
plant shall need to be enlarged, rebuilt or re-equipped
whether due to increased use, obsolescence, exhaustion or
otherwise, and no new assessable front foot benefits arise
therefrom or such as may arise do not fairly represent all
the benefits of such new re-equipment or enlargement since
it serves in whole or in part territories already assessed
on a front foot basis for the service to which such new re-
equipment or enlargement is an improvement, then if the
depreciation and other reserves applicable to this plant
improvement plus any newly assessable front foot benefits
(if any) are not sufficient to construct or finance such
re-equipment or enlargement, the Commission may certify
to the Board of County Commissioners the deficiency, the
assessable value of the sanitary district or districts to be
served by such re-equipment or enlargement and an ad
valorem tax not to exceed ten cents per one hundred dollars
of assessable value and the Board of County Commissioners
may levy such tax on the assessable property within the
district or districts benefited.

430G. Whenever the plans and specifications for water
supply, sewerage or drainage systems for any sanitary dis-
trict shall have been completed and the Commission shall
have decided after opportunity for a hearing has been
given to proceed with the construction thereof, it shall ad-
vertise, by notice in one newspaper published in said
County and such newspapers and technical press as it may
deem proper, for bids for the construction of said system
or systems, in part or as a whole, as in its judgment may
appear advisable. The contract shall be let to the lowest
responsible bidder, or the Commission may reject any and
all bids, and, if in its discretion the prices quoted are un-
reasonable or unbalanced, it may re-advertise the work or
any part of it or may do any part or all of the work by day
labor; provided that at any time the Commission may, in
its discretion, expend by day labor for construction work
an amount not exceeding One Thousand Dollars ($1, 000. 00)
without advertising or receiving bids. All such contracts
shall be protected by such bonds, penalties and conditions
as the Commission may require, all of which shall be en-
forced in any court having jurisdiction.
