1740 LAWS OF MARYLAND. [CH. 991

said order at any time without further notice. No private or
semi-public water supply or sewerage installation intended for
the use of two or more buildings or premises shall be con-
structed in any sub-district without the person, firm or corpo-
ration doing the work having first obtained a permit from the
Commission and paid a reasonable charge therefor, and such
plant shall then be installed, maintained and operated under
such rules and regulations as the Commission may require or
devise. The Commission shall have full and complete juris-
diction over all fire hydrants connected with its water system
and no person, firm or corporation shall operate, use or make
connection with the same without the written authority of the
Commission, excepting that no restrictions shall apply to any
bona fide fire department in the discharge of its duties. No
person, firm or corporation shall tamper with, deface, damage
or obstruct any fire hydrant. Any violation of any of the pro-
provisions of this section shall be a misdemeanor punishable
under Section 21 of this sub-title.

SEC. 11. And be it further enacted, That the Commission
shall make such charge as it shall determine to be reasonable
for every, water and sewer connection as provided in this Act,
based upon the width of the street, road, alley or right-of-way
in which the connection is made; provided, however, that the
connection charge on either side of the street, road, alley or
right-of-way shall be uniform. All of the revenue above actual
cost derived from such charges shall be retained by the Com-
mission as a fund for repairs, replacements or any extraordi-
nary expense in the maintenance and operation of the water
supply, sewerage or drainage systems under its control.

SEC. 12. And be it further enacted, That all sums collected
by the Commission for benefits levied against the property
for water supply, sewerage or drainage construction shall be
set aside as a separate fund to be known and designated as the
"Metropolitan Current Interest and Sinking Fund", from
which fund interest shall be paid on all outstanding bonds,
and the balance, if any, transferred to the "Joint Metropolitan
Sinking Fund Account", as provided in Section 6. The Com-
mission, in order to determine the amount which it may
deem necessary, to be levied under Section 6, shall deduct
the amount to its credit in said "Current Metropolitan
Interest and Sinking Fund", plus such amount as the
Commission may estimate that it will be able to collect out
of the benefit theretofore levied by it but not yet paid, from
the whole amount necessary to be raised in any one year for
interest and sinking fund payments on outstanding bonds, and
the balance then remaining to be raised shall be the amount
