SEC. 14. And be it further enacted, That all sums collected
by the Commission for benefits levied against property for
water supply, sewerage and drainage construction shall be set
aside as a separate fund to be known and designated the "CUR-
RENT INTEREST AND SINKING FUND", from which fund
interest shall be paid on all outstanding bonds, and the balance,
if any, transferred to the "JOINT SINKING FUND AC-
COUNT", as provided in Section 7. The Commission, in or-
der to determine the amount which it may deem necessary to be
levied under Section 7, shall deduct the amount to its credit
in said "Current Interest and Sinking Fund", plus such
amount as the Commission may estimate that it will be able
to collect out of benefits 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 to be certified to the County Commissioners of Anne
Arundel County for collection by taxation as provided by Sec-
tion 7.

SEC. 15. And be it further enacted, That for the purpose of
providing funds for maintaining, repairing and operating its
water supply, sewerage and drainage system, and for its oper-
ating and other expenses (including proper depreciation al-
lowances) , and for interest on and the retirement of bonds
as specified in this Act, the Commission is hereby empowered
and directed to make such service rates as it may deem neces-
sary, chargeable against all properties having a connection
with, any water pipe or sewer pipe under its ownership. Said
rates shall be uniform throughout each Sanitary District but
subject to change from time to time, as may be necessary. The
rates for service shall consist of a minimum or ready-to-serve
charge, which shall be based upon the size of the meter on the
water connection leading to the property, and of a charge for
water used, which shall be based upon the amount of water pass-
ing through the meter during the period between the last two
readings, said meter being required to be placed on each water
connection by, and at the sole expense of, the Commission. If
the Commission at any time shall not have meters available to
install in all the properties in a given locality that are con-
nected with the system, then a flat rate shall be charged all
properties in which meters have not yet been installed, which
rate shall be uniform in each district and based on the amount
of water used. Bills for the amount of the charges as above
specified shall be sent quarterly or semi-annually, as the Com-
mission may determine, to each property served, and shall be
thereon payable at the office of the Commission; and if any
bill shall remain unpaid after thirty days from date of send-
