it may deem necessary, chargeable against all properties having
a connection with any water main under its ownership. Said
rates shall be uniform throughout the town of Mt. Airy, but
subject to change from time to time, as 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 con-
nection leading to the property, and of a charge for water used,
which shall be based upon the amount of water passing the
meter during the period between the last two readings, said
meter being required to be placed on each water connction by,
and at the sole expense of the Mayor and Council, of Mt. Airy.
Bills for the amount of the charges as above specified shall be
sent quarterly or semi-annually, as the Mayor and Council of
Mt. Airy may determine, to each property served, and shall
thereupon be payable at the Office of the Mayor and Council of
Mt. Airy; and if any bill shall remain unpaid after thirty days
from date of sending, the Mayor and Council of Mt. Airy shall,
after written notice to be left upon the premises or mailed to
the last known address of the owner, turn off the water from the
property in question and it shall not be turned on again until
said bills shall have been paid. If any bill shall remain unpaid
for sixty days after being sent out by the Mayor and Council of
Mt. Airy, it shall be collectible against the owner of the prop-
erty served, in the same manner as other debts are collectable
in the town of Mt. Airy.
