258 LAWS OF MARYLAND. [CH. 122

unnecessary use of sewers. No private or semi-public water
supply or sewerage installation intended for the use of two or
more buildings or premises shall be constructed in said Sani-
tary District without the person, firm or corporation doing
the work having first obtained a permit from said Commission
and paid a reasonable charge therefor, and such plant shall
then be installed, maintained and operated under such rules
and regulations as said Commission may require or devise.
Any violation of any of the provisions of this Section shall be
a misdemeanor punishable under Section 21 of this Act.

SEC. 11. And be it further enacted, That for every water
and sewer connection, as provided under Section 9, said Com-

the office of the Commission before the actual connection with
any pipe on private property is made; or any owner so desir-

balance shall be paid in three equal annual installments, such
deferred payments to bear interest at the rate of 6. per cent,

be applied by the Commission to the payment of the bonded
debt, as hereinafter provided.

water supply, sewerage and drainage construction, and half of
all sums collected by the Commission for water, sewer and
drain connections, as provided in Sections 8 and 11, shall be
set aside as a separate fund to be known and designated as the
"Current Interest and Sinking Fund, " from which fund inter-

any, transferred to the "Joint Sinking Fund Account, " as
provided under Section 6. Said Commission, in order to de-
