SANITARY SEWER SPECIFICATIONS
I.
Standard specifications of the Clay Waste District and Indiana Department of Highways
CONC. ENCASEMENT
shall apply for all work and materials. Pipe shall be installed in accordance with Section
CONCRETE BENCH WALL
715.
2.
Sanitary sewer pipe shall be PVC in accordance with AS'I'M D -3034 (S.D.R. 35) and
BASE SHALL BE POURED
AS'I'M 2321. PVC pipe shall have grooved bell and gasket. The pipe shall be made of
IN PLACE OR PRECAST BOTH
PVC plastic having a cell classification of 1245413.
.11
PVC sewer fillings shall conform to the requirements of AS'I'M D- 3034 -89 specifications.
12" O.C. EACH WAY
Fittings in sizes through 8" slrall be molded in one piece with elastomeric joints and
Q
minimum socket depths as specified in sections 6.2 and 7.3.2. Fittings 10" and larger
shall be molded or fabricated in accordance with section 7.11 with manufacturers
standard pipe bells and gaskets. Wall thickness of fittings shall be SDR 26 as defined
in section 7.4.1 of the specifications. Gaskets for elastomeric joints shall be molded with
a minimum cross - sectional area of 0.20 square inches and conform to ASTM F -477
specification. Fittings shall be manufactured by Harco or equal.
4.
All sanitary manholes shall be "precast concrete" manholes in accordance with AS'I'M
C -478 and Section 720. O -Rings shall conform to C -443. Kent Seal or equivalent shall
co
also be applied to all joints and between riser rings and castings. Manhole step spacing
V
W
shall be no more than Winches.
5.
13ulyl rubber coating shall be applied around each manhole joint from 6- inches above to
I
6 inclies below each joint. The appropriate primer shall be applied prior to applying the
Z
rubber coating. Inside joints to be filled with precoal plug mate) ial.
6.
The casting elevations are set by plan. However, the castings are to be adjusted in the
Do
field by the Engineer's representative, should a discrepancy occur between plan grade
W
and existing grade. New manhole ring and cover shall be installed to establish grade.
Maximum height of adjusting rings shall be 12- inches.
7.
Backfrll around all structures and all cuts under paved areas with granular material.
Z
'Trenches opening within 5 -feet of pave roadways shall be backfilled with granular
material in accordance with Secticn 211. Backfill under sidewalks shall be granular,
In
unless lire walks are constructed a ninimum of 6 months after backfill has been in- place.
8.
The Contractor shall be responsible for verifying that all state highways, city and county
v,
permits have been obtained by the developer prior to start of cunstrucdon.
9.
'the Contractor shall be required to furnish the developer's Engineer with a set of prints,
Z
0
marked in red pencil, showing actual sewer location and invert, to include lateral
Z
a
location, depth and length. Such "as- built" prints must be received by the Engineer
before the final contract payment can be authorized. The sanitary sewer laterals and
stubs termination shall be indicated on the surface with a metal fence post set
immediately above said termination point.
10.
All sanitary sewer lines upon completion will be required to pass an infiltration weir lest
and a low pressure air test, unless otherwise directed by the Engineer. Said lest shall be
conducted according to NCPI Standard Method, and shall be witnessed by an Engineer
and representative of the Clay Waste District.
11.
Deflection tests shall be performed on all flexible* pipe after the final backfill has been
in -place at least 30 days. No pipe shall exceed a vertical deflection of 5 percent
deflection test results. ( *The following are considered non- flexible pipes: concrete pipe,
ductile iron pipe and cast iron pipe.) The deflection test shall be performed with a nine -
point mandrel. Proving rings shall be available.
12.
All mandrel testing shall be observed by a Professional Engineer for certification and a
representative of the Clay Waste District.
13.
'Flee ends of laterals are to be plugged light with a braced plastic disc or cap capable of
withstanding a low pressure air lest without leakage.
14.
Bedding for flexible pipe shall be No. 8 crushed stone from 6- inches below the pipe to
12- inches above the pipe. Bedding for rigid pipe shall be No. 8 crushed stone from 6-
inches below the pipe to the spring line of the pipe and from this point to 12- inches
above shall be fill sand or equivalent. Manholes shall be placed on no less than 6- inches
of No. 8 crushed stone bedding.
15.
Water and sewer line crossings and separations shall be in accordance with Ten States'
Standards.
16.
'french shall be opened sufficiently ahead of pipe laying to reveal obstructions, and shall
he property protected and /or barricaded when left unattended.
17.
No Water shall be permitted to flow into the sanitary sewer system during construction.
Contractor shall utilize a pump to keep the water level below the pipe. Pump discharge
shall be directed to a storm outlet. Any pipe entering existing sewers shall be plugged
with mechanical screw type, braced plugged until such time as all tests on the sewers
have been completed and the lines have passed all punch lists.
18.
All sewer laterals installed by file mainline Contractor shall be bedded the same as the
main line sewer.
19.
Forty -eight (48) hours notice shall be given to the Clay Regional Waste District prior to
the start of sewer construction. Also, 48 -hours notice shall be given prior to any testing
done on the sewer.
20.
Manhole castings shall be stamped "SANI'T'ARY SEWER" (Neenah Casting R 1642 or
equal) and he self - sealing type. Waterproof castings shall be Neenah R- 1916 -F1 and
stamped "Sanitary Sewer ".

'1•he Contractor shall provide measurements of the slope of the sewer for each manhole
_,
section as construction progresses. Such measurements shall be certified by a Registered
Land Surveyor or Engineer and be available on -sile for observation by the District's
