will not exceed twenty-five per centum (25%) of the assessed
property value as fixed for county taxation purposes within said
area or locality, and if they find that the proposed project is feasible
from an engineering and financial standpoint, and if, in addition
thereto, they shall find that it is necessary to the public health,
safety and welfare of the residents therein that said sanitary
district be established or enlarged, they may in their discretion re-
verse any decision of the commission denying the petition to create
or enlarge a sanitary district. If such governing body or governing
bodies do not so find, they may in their discretion reverse any
decision of the commission creating or enlarging a sanitary district.
If the final decision is in favor of establishing or enlarging a sani-
tary district or, in the event no appeal is taken from an order of
the commission creating or enlarging a sanitary district, if the
governing body of the county in which said locality lies consents
thereto, the commission shall cause plats of such locality as finally
determined by the commission to be made under the supervision
of its engineers, showing the boundaries of such locality, one copy
of which plat shall be filed in the office of the commission, one in
the office of the governing body of the county or counties in which

said locality lies and one, indexed "....................................Sanitary District,"

shall be filed in a plat book in the office where the land records of
the county or counties are kept; and upon the filing of said plat
and the approval of said locality by the governing body or govern-
ing bodies and the commission, such sanitary district shown on
said plat shall be, and the same is hereby designated and constituted
for the purpose of this subtitle to be a separate sanitary district
or to be a part of a previously created, contiguous sanitary district,
in accordance with the determination of the commission and, if desig-
nated a new sanitary district, shall be given by the commission a
distinctive name, shall be subject to all the provisions of this sub-
title and shall be a separate taxing district, and the filing of said
plat shall constitute legal notice to the public of such action of the
commission. Where a sanitary district has been created pursuant
to this section, it shall be unnecessary for the commission to comply
with Section 653 of this article with respect to any project described
in the notice published pursuant to this section.

(a) The commission may cause surveys, plans, specifications, and
estimates to be made for water '[and] , sewerage and solid waste
disposal systems and acceptance facilities in those portions of the
county or counties in which the commission exercises authority,
and may divide each sanitary district into water [and] , sewerage
and solid waste disposal districts in such way as shall, in its judg-

promote convenience and economy of installation and operation.
Whenever, and as such plans are completed, the commission shall
give notice by publication in one or more newspapers published
within such county or counties for three weeks, and shall state in
said notice the probable cost of the contemplated improvements,
based on then available engineering estimates, which cost figure
shall not be final for any purpose other than such notice, and shall
further state therein that plans of the improvements may be in-
spected at the commission's office and that any person interested in
