faucets or hydrants in use on such premises or in accordance with
any other reasonable formula the Commission may adopt. Any such
schedule may also include special rates for charitable, religious or
public institutions, the property of which is exempt from State,
County and municipal taxation but, unless any such special rate is
adopted, said institutions shall be liable for water consumed on the
same basis as all other consumers. Bills for the amount of water
rates or charges, computed with respect to each property served in
accordance with the above mentioned schedules, shall be sent quar-
terly or semi-annually as the Commission may determine in the
resolution adopting any such schedule, such bills to be sent to each
property served and to be payable within thirty days from date of
sending at the office of the Commission designated on each such bill.
The Commission may, if requested by the owner of any property, bill
tenants of any such property served for water consumed by such
tenants, rather than such owner but, in making any such election, the
owners of any such properties shall not be excused from liability
for any unpaid bills for water consumed on the premises by such
tenants or otherwise. If any such bill remains unpaid after thirty
days from date of sending, the Commission may, after written notice
left on the premises, or mailed both to the tenant, if any, and to the
owner at his last know address, turn off the water from the property
in question and said water shall not be turned on again until said bill,
together with all other bills for water service chargeable against
said property shall have been paid in full, together with such penalty
as the Commission may have fixed in the above mentioned schedule
of rates. If any such bill shall remain unpaid for sixty days after
having been sent by the Commission, as aforesaid, it shall be col-
lectible from the owner of the property served, by a suit, in the same
manner as private debts are collectible in the County but, whether
or not judgment is received on any such delinquent bill, the amount
thereof, including any such judgment, shall constitute a lien against
any such property to the same extent and in the same manner as
provided in Section 539 of this sub-title for special benefit assess-
ments.

(c) All revenues collected by the Commission from water rates and
charges shall be applied, first, to payment of the cost of operating,
maintaining and repairing the water system or systems of the Dis-
trict in such sub-districts from which such revenues are obtained
and also for the cost of operating overhead of said District. Secondly,
the Commission may reserve and set aside from said revenues appro-
priate depreciation reserves for expenditure on replacements of worn
out equipment or facilities forming part of any such water system,
or for improvements thereto. After making appropriate provision for
such expenditures and reserves, the Commission shall apply such rev-
enues to the payment of the principal of and interest on the bonds of
the Commission issued pursuant to the provisions of Sections 534 or
535 of this sub-title with respect to the water system producing such
revenues, or for the prior redemption of or greater security for any
such bonds, in accordance with the resolution or trust indenture of
the Commission pursuant to which such bonds are issued.

(d)  All schedules of rates and charges for water adopted and en-
forced by the District pursuant to this Section shall not be subject
to review, regulation or control by any agency of the County or of
the State, including the Public Service Commission of Maryland.
