private sewer, septic tank or cesspool any ashes, cinders, solids, rags,
flammable, poisonous or explosive liquids or gases, oils, grease or any other
thing whatsoever which would, or could cause damage to the public sewer,
private sewer or private sewage disposal system except that these provisions
shall not have the effect of eliminating or superseding any of the require-
ments of the Industrial Waste Ordinance of the City of Fort Worth.
(b) No rainwater downspout or area, yard, street or gutter drains shall
be connected directly or indirectly to any sanitary sewer. Subsurface
drainage facilities that discharge to the surface material which would be
injurious to the public health or safety may be connected to the sanitary
sewer system but only after such connection has been specifically approved
in writing by the Director of the Water Department and the Chief Plumbing
Inspector or their authorized representatives. Application for approval for
the connection of such subsurface drainage facilities to the sanitary sewer
system must be made to the Chief Plumbing Inspector upon forms furnished by
said inspector and accompanied by appropriate plans of the proposed con-
nection. Water Department approval for such subsurface drainage connections
will not be granted unless:
B63
(1) The sanitary sewer• line to which the connection is to be made
has sufficient surplus capacity under maximum service conditions to accommo-
date the discharge rate from the subsurface drainage facilities; and
(2) All of the subsurface drainage discharge into the sanitary sewer
line through the proposed connection passes through an approved pumping system
in which the rate of discharge is controlled at the rate which has been ap-
proved by the Director of the Water Department or his authorized representa-
tive.
The owner or occupant of any building being served by any such
subsurface drainage connection to the sanitary sewage system shall pay
monthly charges to the City of Fort Worth for such connection determined upon
the following basis: One and 25/100 Dollars ($1 .25) for each five gallons
per minute or fraction thereof pump discharge rate to the sanitary sewer

shall be provided. After the cushion has been graded, the pipe shall be
laid from the main to the building drain with the bells of the pipe pointed
upstream. Pipe shall be laid and joints made in accordance with the manu-
facturer's instructions and with the specifications herein contained. After
the laying of the pipe has been completed, the trench shall be left open
with pipe and cushion exposed until after the work has been inspected, tested.
and approved by the Plumbing Inspector.
After approval by the Plumbing Inspector, the pipe shall be blinded with
"sandy gravel material'' as herein specified to a level at least six inches
above the top of the barrel of the installed pipe. The blinding material
shall be worked or shovel tamped around the barrel of the pipe in such man-
ner that the entire pipe is enclosed and supported.
In the construction of building sewers of cast iron or soil pipe, the
trench shall be excavated to a depth below the bottom of the barrel of the
pipe sufficient to permit the bells of pipe to rest on the bottom of the
trench, except where the bottom of the trench is in rock. Where the bottom
of the trench is in rock, such rock shall be removed to a depth of at least
3 inches below the bottoia of the barrel of the pipe and a uniform cushion
composed of not less than 3 inches of ''sandy gravel material'' as herein
specified shall be provided. After the trench has been appropriately pre-
pared, pipe shall be laid and joints made in accordance with the manu-
facturer's instructions and with the specifications herein contained. After
the laying of the pipe and cushion, if any, the wort: shall be left exposed

RULES FOR SIZING THE WATER SUPPLY SYSTEM
The following is the required order of procedure for sizing the water
supply system.
A3.1 Decide what is the desirable minimum pressure that should be
maintained at the highest fixture in the supply system. If the highest
group of fixtures contains flush valves, the pressure for the group shall
not be less than fifteen (15) psi . For flush-tank supplies, the available
pressure shall be not less than eight (8) psi .
A4.3 Chart A-5 shall be used for ferrous pipe with only the most
favorable water supply as regards corrosion and caking. If the water is
hard or corrosive, Charts A-6 or A-7 shall be applicable. For extremely
hard water, additional allowances for the reduction of capacity of hot water
lines in service shall be made.
A5.1 The required size of branches and risers shall be obtained in the
same manner as the building supply by obtaining the demand load on each
branch or riser and using the permissible friction loss computed in Section
A3
A5.2 Fixture branches to the building supply, if they are sized for the
same permissible friction loss per one hundred (100) feet of pipe as the
branches and risers to the highest level in the building, may lead to in-
adequate water supply to the upper floor of a building. This shall be con-
trolled by: (1) Selecting the sizes of pipe for the different branches so
that the total friction loss in each lower branch is approximately equal to
the total loss in the riser, including both friction loss and loss in static
pressure; (2) by throttling each such branch by means of a valve until the
preceding balance is obtained; (3) by increasing the size of the building
supply and risers above the minimum required to meet the maximum permissible
friction loss.
A6.1 A velocity greater than fifteen (15) feet per second in the main
risers, or principal branches shall not be employed, as objectionable line
noise is likely to result
A6.2 If a pressure reducing valve is used in the building supply, the
developed length of supply piping and the permissible friction loss shall be
computed from the building side of the valve.

BUILDING 12/21/70 G-1675 Recommended Plumbing Code 2 of 2
On September 29, 1968, the City Council appointed a Plumbing Code Review Com-
mittee to review the national model plumbing codes and to recommend one as
the model code for the City of Fort Worth. After studying the existing model
codes, the Committee agreed to recommend the Uniform Plumbing Code, promul-
gated by the International Conference of Building Officials, as the model for
the City of Fort Worth Plumbing Code.
The proposed Plumbing Code represents the work of thirty meetings conducted
by the Plumbing Code Review Committee for periods lasting from several hours
to all day in deliberation of various aspects of the Code. In addition, many
informal meetings and discussions were held.
Nature of Proposed Code
The proposed new Ordinance, which is the first major overhaul of the Plumbing
Code since 1952, is essentially the 1970 Uniform Plumbing Code. Only those
changes and modifications necessary to relate the code more appropriately to
local conditions are recommended.
Certain of the changes, typified by the Venting Provisions, permit a much
simpler and more economical procedure than that required by the Uniform plumb-
ing Code.
The bulk of the proposed Code provisions are already in current local practice,
so that the change in regulatory effect will be minimal. However, the body of
the Code will be completely revised, reorganized and made far simpler to use
and interpret. The proposed Ordinance will require plans to be submitted on
all projects where more than forty plumbing fixtures are involved and that
plans with more than one hundred fifty fixtures have the Seal of a Registered
Professional Engineer.
The proposed Ordinance acknowledges and accepts new materials and methods
and separates from the Plumbing'Code those requirements which will now come
under the jurisdiction of the proposed Mechanical Code.
While some increased construction costs can be expected in some areas, such
expense will be more than offset by changes in material and construction re-
quirements made possible by the proposed Ordinance. Under the proposed Ordi-
nance, the $.75 per fixture permit fee will be increased to $1.00 per fixture.
The proposed Ordinance requires the Plumbing Code Board .to review the annual
amendments to the Uniform Plumbing Code adopted by the International Confer-
ence of Building Officials, as well as other suggested amendments. Subsegoently,
the Board will submit to the City Council yearly its recommendations for re-
visions to the Plumbing Code of the City of Fort Worth.
