Process Description
Konica-Minolta
Geo-thermal Test Well
Konica Minolta located in Whitsett, North Carolina is submitting well registration
documentation for one Type SQW well. This well will be located on their property at the
site designated "Test Well #1" on drawing PR--798--800-PS, Rev.13.
This well will be used to cool approximately 20 gallons per minute (gpm) of jacket cooling
water before the jacket cooling water is transported to the fire water tank. This is a test
well for evaluation purposes only. See drawing number 1006-007-Pl, Process &
Instrumentation Diagram.
Exis'ling Process
Both city water and well water from on site water wells are used throughout the Konica
facility. Initially, this water is pumped to the firewater tank. Once in the rirewater tank
it is designated "Process industrial water". Water from this tank is pump into a closed loop
to cool jacketed process tank. Jacket cooling water then gravity drained into the Jacket
water reclaim tank. Water from this tank is then pump back into the Firewater tank by a
Goulds MXT Model: 3196 pump. The transporting pipe from the Jacket water reclaim
tank to the Firewater tank is a 3" Galvanized Steel screwed pipe.
Modific ations to the Fxisting S ystem-Geo Thermal Test Well
The pipe system between the Gould's pump and the Firewater tank will be modified as
follows: 1 each 3 way control valve will be installed in this line. It will control flow and
direct water downward approximately 25 feet through Galvanized steel pipe. A bimetal
connector will connect the Galvanized steel pipe to a 1 ½" ffigh Density Polyethylene
(HDPE) pipe 300 foot down into the Geo-thermal test well. The HDPE pipe is a Unicoil. It
will have a "u" bend at the bottom. Water will then proceed 300' back up to the ground
surface where it will go through another Bimetal connector. It will then go upward 25' in a
3" Galvanized steel pipe into a tee and onward to the Firewater tank. There will be a check
valve between the three way control valve and the tee to prevent backflow conditions.
There will also be one isolation valve on each pipe vertical leg between the pipe rack and
the test well. Only water will be in this line there are no chemical contaminants.

permeability shall be determined by using an experimental set-up as outlined in
ASTM D 5084-90, and shall have a maximum nominal permeability rate of lx 10-
5 cm/sec.
E. Grout Mixing : The grout shall be mixed by using a continuous mixer -batch
mixing of grout shall not be allowed. The maximum water content of the grout
shall not exceed 17% by dry weight of the grout mix. The grout shall be mixed
with the Enlink Continuous Grout Mixer or approved equal, having an on-board
rotometer to precisely control the amount of water added. The grout shall contain
a suitable admixture to achieve a slump of 6 to 11 inches at 17% water content,
and shall exhibit an ASTM unconfined 28 day compressive strength greater than
3,000 psi. The mixed grout shall have a minimum specific gravity of 2.18 or
density of 18.1 lbs/gallon.

beginning work.
2.05 U-BEND/PIPE ASSEMBLY
A The u-bend fitting shall be injection molded from PE 3408 resin having a cell
classification of 345444 with a UV stabilizer of C. U-bends constructed by fusing
two 90 degree bends together shall not be allowed. The u-bends shall be factory
butt fused to continuous lengths of SOR 11 pipe which has been extruded from
resin identical to the u-bend. The u-bend/pipe assembly shall have pipe lengths
long enough to reach to final grade from the bottom of the bore so that no field
fusion welds are required below the header pit elevation. All u-bend assemblies
shall be factory pressure tested to 100 psi for a minimum of 5 minutes. On
completion of successful testing, the pipe ends shall be immediately plugged to
prevent foreign objects from entering the pipe.
PART 3 EXECUTION
3.01 EXAMINATION
A Section 01300 -Administrative Requirements: Coordination and project
conditions.
B. Examine areas and conditions under which ground heat exchanger systems are to
be installed. Do not proceed with work until unsatisfactory conditions have been
corrected in a manner acceptable to manufacturer's recommendations.
3.02 INSTALLATION
A Loop Insertion and Grouting
1. Drill borehole in accordance with local, State or Federal requirements. Follow
all requirements for borehole drilling as prescribed by the State of North
Carolina. The contractor will be responsible for receiving permission in
writing from the State of North Carolina prior to proceeding and shall be
responsible for maintaining any drilling logs that may be required.
2. A copy of the soil analysis made from the soil removed from a test well bored
at the site can be found at the end of this specification (Figure 1 ).
3. The borehole shall be clean and of sufficient diameter to facilitate the
installation of the u-bend assembly and a tremmie pipe, with a maximum
borehole diameter as indicated on the drawings. Care shall be taken so as
not to stretch, crush, cut, or kink the pipe during installation.
4. Immediately prior to being placed in the borehole, the u-bend assembly shall
be flow tested to ensure that there are no kinks, bends or pinches. The test
shall consist of forcing clean water into one end of the assembly, and visually
inspecting the discharge. If damage or an obstruction exists, that loop shall not
be used.
5. If the driller has drilled deeper than shown on the drawings, special
precautions shall be taken so that the sealed pipe ends do not "drop" into the
open borehole below graded surface.
6. If a buoyant condition exists, the u-bend shall be staked and .tied at the surface
to prevent the assembly from "floating" out of the bore prior to the "setting" of
the cementitious-based grout.
7. Prior to grouting, the u-bend assembly shall be pressurized with water to
achieve a minimum internal pressure of 50 psi, and the ends shall be
temporarily plugged to maintain this pressure. To prevent the collapse of the
pipe resulting from the external force created by the grout's hydrostatic
pressure, the pressure in the u-bend assembly shall be maintained until the
grout has set.
8. Since some settling may occur after initial placement of the grout material, the
installer shall monitor each borehole and continue adding grout as required to
bring the grout level up to the trench grade.
9. Borehole locations shall be individually surveyed after drilling is complete.
The survey shall locate all boreholes accurately from one or more known local
survey benchmarks. The contractor shall furnish the Engineer/Owner a
drawing indicating the borehole locations.
3.03 TESTING
All circuits of closed-loop ground heat exchanger system shall be water filled
and pressure tested to at least 100 psi for a minimum of 1 hour prior to
backfill. Every weld shall be visually and physically examined. If any leaks
are detected at a fusion joint, it shall be cut out and replaced, at which time
that section shall be re-tested according to this section. At the expense of the
contractor a thermal conductivity test on a borehole selected at random by the
Owner/Engineer shall be run to ensure that the borehole thermal performance
is consistent with the Engineer's design assumptions and the contractor's
installation practices. The TC test data must be provided to the
Owner/Engineer within 3 days of completion of the test. The TC test must be
for run a minimum of 40 hours. In the event that the analysis of the returning
water temperatures indicates a higher borehole thermal resistance value (i.e.
lower grout thermal conductivity) than the minimum design value, additional
boreholes will be drilled to compensate for this deficiency at the contractor's
expense.
3.04 FIELD QUALITY CONTROL
A. Before backfilling all sub grade piping shall be flushed and purged of air and flow
tested to ensure all portions of the closed-loop ground heat exchanger are properly
flowing. A portable temporary purging unit shall be utilized and shall consist of
the following:
1. Purge pump -high volume and high head.
2. Open reservoir.
3. Filter assembly with by-pass.
4. Flow meter.
5. Pressure gage.
6. Connecting piping.
7. Connecting hoses.
B. Using the purging unit described above, flush and purge each section free of air,
dirt and debris. A minimum velocity of 2 feet second in each piping section must
be maintained for a minimum of fifteen minutes to remove all air. A change of
more than 1 inch in the level of fluid in the purge pump tank during pressurization
indicates air still trapped in the system. The flushing and purging operation shall
be conducted with the supply and return lines to the building capped and sealed at
the flange termination connection within the building. Supply and return lines to
the building shall be filled as full as possible with water. Building mechanical
contractor will be responsible for flushing and purging the interior portion of the
system and a final purging of the entire system.
C. Utilizing the purging unit, conduct a pressure and flow test on the ground heat
exchanger to ensure the system is free of blockage. If the flow test indicates
blockage, locate blockage using manufacturer's recommendation, remove
blockage, then re-purge and conduct the pressure and flow test again until all
portions of the system are flowing properly. The flow test must be observed and
approved by the Owner/Engineer or his designate before the system is to be
considered completed.
3.05 FINISH GRADE PREPARATION
A. Perform all finish grading necessary to bring site to required finished elevations.
Finish grading shall consist of preparing topsoil ready for lawn work. Use topsoil
stockpiled on the site during earthwork operations and provide any additional
topsoil required. Do not start work until underground utilities are completely
installed and heavy hauling finished.
B. After completion and approval of finish grading, remove any excess topsoil from
site, unless otherwise directed in writing by the owner, leave finish graded areas
clean and well raked, ready for lawn work.
