[PART 3: EXECUTION]{.underline}

3.1 PREPARATION:

A. Clearing: Worksite clearing shall be \[limited to an area 100 by 100
ft.\] \[as designated and staked by the Contracting Officer.\]

B. Site Preparation: Surface disturbance at sites shall be minimized.
However, the Contractor shall be allowed to level construction sites as
necessary for windmill maintenance operations. Construction shall be as
staked by the Contracting Officer. Resultant cut or fill slopes shall
not be steeper than 4:1, unless staked otherwise.

C. Removal of Tower and Mill: Prior to removal of the tower and mill,
the pump shall be disconnected from the \[pipeline\] \[water storage
tank\]. The pump shall be reconnected to the \[pipeline\] \[water
storage tank\] upon completion of the maintenance of the tower and mill.
Lay the existing windmill and tower on the ground without damaging it.

3.2 INSTALLATION:

A. Maintenance of Tower and Mill: The Contractor shall do necessary work
to ensure that the windmill and tower are in proper working condition.
This shall include, but not be limited to: tightening loose nuts and
replacing missing nuts and bolts, repairing or replacing damaged
components, replacing unserviceable, missing, or damaged components,
adjusting components when necessary and lubricating the windmill.

B. Setting of Tower and Mill: After appropriate maintenance has been
accomplished, the windmill and tower shall be erected and assembled
according to the manufacturer\'s instructions (except lubrication of the
mill shall be done after it is in its final position). Each leg of the
mill shall be bolted to anchors set in concrete. If one or more anchor
posts are unserviceable or missing, the Contractor shall set new anchors
in concrete. Repair or replacement anchor posts and associated concrete
shall be of the appropriate size and installed according to
manufacturer\'s recommendations. The tower and mill shall be accurately
centered and plumbed over the well.

C. Alignment of Tower and Mill: Each tower and mill shall be set in a
plumbed vertical line over the centerline of the well casing. The
Contractor shall test the plumbness of the installation by hanging a
plumb bob from the pumprod connection.

D. Pumping Equipment: The Contractor shall \[furnish\] \[and\]
\[install\] replacement drop pipe, pump rod, well cylinder, pump pole,
piston (polished) rod, stuffing box, packing, and sanitary well seal
according to manufacturer\'s instructions. Threaded joints shall be
properly lubricated prior to final installation.

1\. Pump Pole: A pump pole of sufficient length shall be installed
between the windmill and the pump according to the manufacturer\'s
instructions. Threaded joints shall be properly lubricated with
anti‑seize compound prior to final installation.

2\. Drop Pipe: Drop pipe shall be installed to the depth specified. Drop
pipe ends shall be reamed to remove burrs prior to installation. The
well cylinder barrel shall be fitted to the drop pipe prior to insertion
into the well. The drop pipe shall be fitted with a final coupling,
short nipple, tee and another short nipple with all above the well seal.
The uppermost nipple shall be fitted with suitable fittings to receive
the stuffing box. \[A 1/8‑inch diameter hole shall be drilled in the
drop pipe 8 ft below the ground surface to drain that portion of the
drop pipe and prevent damage by freezing.\]

3\. Polished Rod Assembly: The polished rod, brass sleeve and stuffing
box shall be fitted and assembled according to the manufacturer\'s
instructions. The polished rod, pump rod, and plunger assembly shall be
raised a minimum of 6 inches, or at a distance specified by the
Contracting Officer, above its lowest position in the well cylinder and
the guide stop shall be locked in this position. A legible, waterproof
tag shall be attached to the polished rod warning that the rod drive
must be attached to the polished rod when in the down stroke to prevent
damage to the rod and cylinder.

4\. Pump Rod: Pump rod shall be installed to the depth specified. The
pump rod shall be properly fitted to the cylinder plunger and the
polished rod. Rod sections shall be straight and true and in lengths of
20 or 21 ft, except the final top section which will be shortened by
removing a midshaft portion to achieve the proper overall pump rod
length. The midshaft reconnection shall be achieved by threading and
coupling, electric welding, or other approved method. The final overall
length shall be such as to expose approximately 4 inches of the polished
rod brass sleeve, above the stuffing box when in the low rod position.

5\. Well Cylinder Assembly: The well cylinder and check shall be
properly assembled and fitted to the drop pipe according to the
manufacturer\'s instructions.

6\. Sanitary Well Seal: The well seal shall be fitted securely on the
well casing and adjusted to insure a good seal. Special attention shall
be given to the installation of the seal to provide a suitable anchor
for the suspension of the drop pipe.

E. Grouting: The upper \[[ ]{.underline}\] ft of the casing shall be
grouted. Place the grout to prevent surface water and other impurities
from entering the well by filtration along the surface and the casing.
The upper limit of the grout seal shall be the well platform. Force the
grout from the bottom of the grout space toward the ground surface in a
continuous operation, using a tremie pipe. Allow grout to set for 3 days
before doing work that may disturb it or cause it to crack. Protect the
grout from damage and ensure that proper curing occurs during the 3‑day
setting period.

F. Access Port: Install access port on the casing. The port shall
consist of a one‑inch standard steel‑pipe coupling filet welded in the
side of the casing so that the centerline is approximately 30 degrees
from the vertical. The top of the port shall be approximately one ft
above ground level. The coupling shall be equipped with a threaded plug.

G. Concrete Well Platform: Construct a concrete platform around the well
as shown on the drawings, extending 6 inches above finished grade.
Finish concrete with a smooth \"wood float\" or \"broomed\" finish. The
top of the casing shall be cut off to the elevation designated by the
Contracting Officer. Concrete shall be according to Section 03306 ‑
Minor Concrete.

3.3 FIELD QUALITY CONTROL:

A. Testing: When the windmill and well equipment are installed, the
Contractor shall use the windmill to pump a minimum of \[[ ]{.underline}
gal of water.\] \[[ ]{.underline} hr.\] The Contractor shall provide
water storage facilities if none are present at the site. The Contractor
shall determine pumping rates at the wind velocities given by the
Contracting Officer and furnish the test results to the Contracting
Officer. The Contractor shall check to see if the cylinder is
functioning and not bottoming out and that the windmill brake and other
appurtenances are functioning properly. Problems shall be corrected by
the Contractor.

B. Sanitary Protection of Well: The Contractor shall protect the well
during the construction period to prevent tampering or seepage of
contaminated water, petroleum products, or other contaminants into the
well from the ground surface.

C. Correcting Contamination: If the well becomes contaminated, or water
with undesirable physical or chemical characteristics enters the well,
corrective work, including the supplying of seals, sterilizing agents,
or other materials necessary to prevent contamination of the aquifers,
shall be performed at the Contractor\'s expense.

D. Disinfection:

1\. General: After the windmill, tower, and pumping equipment have been
installed, the well shall then be disinfected with a chlorine solution.
CAUTION: When calcium hypochlorite is used as the source of chlorine, it
should be dissolved or suspended in water when introduced into solvent
welded PVC pipe, since the dry chemical can react violently with solvent
welding materials. Other precautions listed on the calcium hypochlorite
container shall be observed.

2\. Chlorine Solution: The chlorine solution used for disinfecting the
well shall be of such volume and strength and shall be so applied that a
concentration of at least 100 ppm of chlorine is obtained in the well.
Prepare and apply chlorine solutions according to the following table
and to the satisfaction of the Contracting Officer. The disinfection
solution shall remain in the well for a period of at least 12 hr.
