with the water supply or sewerage system under its jurisdic-
tion, and may order and require such changes in all water or
sewerage connections, or plumbing, as they may deem necessary
to eliminate improper use of water or sewers, or to correct de-
fective plumbing. No private water supply or sewerage instal-
lation shall be constructed in the town of Gaithersburg without
the person, firm or corporation doing the work having first ob-
tained a permit from the Mayor and Council and paid a rea-
sonable charge therefor, and such plants shall then be installed,
maintained and operated under such rules and regulations as
the Mayor and Council may require. Any violation of any of
the provisions of this section shall be a misdemeanor punish-
able under Section 16 of this Act.

SEC. 9. And be it further enacted, That for the purpose of
paying the interest and sinking fund on that part of the bond
issue covering the cost of water and sewer connections, as pro-
vided under Section 7, the Mayor and Council shall make such

assessment for each of such connections as they shall determine
to be necessary. All of said assessments for water connections
shall be uniform throughout the town, and likewise said as-
sessments for sewer connections shall be uniform, subject, how-
ever, to revision annually by the Mayor and Council as costs
and conditions may require. Assessments for water and sewer
connections shall be payable annually for a period of years co-
extensive with the period of maturity of the bonds out of the
proceeds of which they were constructed; provided, however,
that the Mayor and Council shall establish a fixed uniform
charge for all water connections and a fixed uniform charge
for all sewer connections, fully sufficient to cover their cost and
chargeable annually, which any property owner may elect to
pay in one sum, at the time the connection is extended to his
property line by the Mayor and Council, instead of said annual
payments for said connection as above provided; and provided
further, that any property owner, at any time during the life
of a connection assessment, may extinguish the same by pay-
ment in cash of an amount, which, if put at interest at 3 1/2 per
cent, compounded annually, would yield an annuity equal to
the annual connection assessment for the period for which said
assessment has yet to run. Water and sewer connection assess-
ments shall have the same priority rights, be payable at the
same time and in the same manner, be enforceable in the same
way, and be subject to the same penalties for non-payment, as
front-foot assessments.
