1. GENERAL - Longitudinal water and sanitary sewer pipelines shall
be placed on uniform alignment three (3) to ten (10) feet from the
right of way line. The minimum depth of cover shall be twenty-four
(24) inches for non-plastic lines and thirty (30) inches for plastic
lines. If a nonmetallic line is installed, a durable metal wire or
other device shall be concurrently installed for detection purposes.
Each line may be installed with enough vertical flexibility to prevent
excessive stresses, however, horizontal "snaking" of the line is
prohibited.
The utility agency shall place identification markers at the right of
way line in sufficient number for longitudinal installations and at
each highway crossing.
All paved side streets crossed by a longitudinal line within TxDOT
right of way must be installed as outlined in item #2 below.
2. CROSSINGS - Highway crossings are to be installed at or near right
angles to highway and must be installed with an' encasement pipe.
Encasement pipe is also to be installed under normal center medians
and is to'extend from the top of backslope for cut sections and five
(5) feet beyond the toe of slope for fill sections, unless an
additional length is required as outlined in the "TRENCH EXCAVATION
AND PIT LOCATION" specification.
All crossings under existing pavement must be installed as outlined
in the "CONSTRUCTION OF HIGHWAY CROSSINGS BY BORE" Specification.
The depth of cover for crossings shall be twenty-four (24) inches for
non-plastic pipe and thirty (30) inches for plastic pipe under
ditches. The encasement pipe must be a minimum of eighteen (18)
inches or 1/2 the diameter of the pipe, whichever is greater, below
the bottom of the pavement structure.
The encasement shall consist of a steel pipe around and outside the
carrier pipe and support the load of the ground above the pipe, the
highway, and the superimposed loads thereon, including construction
equipment. The strength of the enca~ement pipe shall equal or exceed
the structural requirements for highway drainage culverts covered
under ASTM specifications.

barricades and warning devices to protect the traveling public.
Topsoil shall be kept separate from other excavation material, and be
replaced in accordance with "SPECIFICATIONS FOR BACKFILL."
All pits and trenches shall be kept free from standing water. If
trenches and/or bore pits are left open for extended periods of time
without a continuous progression of work, the utility will be required
to backfill the trench and/or bore pits. Any 'other pit will not be
left open for more than a forty-eight (48) hour period.
In all excavations where sloughing is likely to occur, shoring will

utility agency or contractor shall be responsible for maintaining
trench excavation protection as required by provisions of Part 1926,
Subpart P - Excavations, Trenching and Shoring of OSHA Standards.
2. TRENCHING - Longitudinal installations must be placed as near a

machine or backhoe may be used. A backhoe will be required if a
uniform alignment can't be maintained by use of a trenching machine.
3. SAFETY CLEAR ZONE DISTANCES - Minimum clear zone distances required
for trench excavations and bore pit locations are as follows.

BACKFILLING ---,, "
1. GENERAL - As soon as practical, all portions of the excavation
shall be backfilled. Trenches and pits shall be backfilled with the
material obtained from the excavation or from other sources. BaCkfill
material will be free from stones of such size as to interfere with
compaction; free from large lumps which will not break down readily
under compaction; and free from frozen lumps, wood or other extraneous
material. The TxDOT Inspector may reject any material containing more
than twenty (20) percent by weight of material retained on a three (3)
inch sieve.
The portion of top soil removed from the original excavation shall be
replaced, as nearly as feasible, in its original position.
2. DEPTH OF LIFTS - That portion of backfill below the top of pipe
shall be placed in uniform layers not to exceed eight (8) inches in
depth (loose measurement).
Backfill above the top of pipe shall be placed layers not to exceed
ten (10) inches in depth (loose measurement). If the backfill is to
support a portion of roadway or embankment, then the material will be
placed in uniform layers not to exceed eight (8) inches in depth
(loose measurement).
3. PROCEDURE FOR COMPACTION - Each layer of backfill material, if
dry, shall be wetted uniformly .to the moisture content required to
obtain a density comparable with the adjacent undisturbed soil and
shall be compacted to that density by means of mechanical tampers or
rammers. The use of rolling equipment of the type generally used in
compacting embankments will be permitted on portions which are
accessible to such equipment. Water jetting or ponding will not 'be
permitted.
Special care shall be taken to ensure thorough compaction of material
placed under the haunches of the pipe.
Cohesionless materials, such as sand, may be used for general
backfilling purposes. Compaction of cohesionleSs materials shall be
done with vibratory equipment.
4. RESTORATION OF RIGHT OF WAY - Prompt replacement of sod, removal
of debris, and any other restoration necessary to restore the right
of way to a condition equal to that which existed prior to the utility
installation will be required. In areas of erosion, the use of
stabilized backfill may be required. Should settlement or erosion
occur within six(6) months of the utility installation, the utility
agency will be required to reshape, reseed, and/or resod the area.
