Drilling under Lot #7 Parking Area. Pipe will be 7 feet under the concrete area.

E/One pump packages with concrete ballast applied ready for installation on individual lots.

South side of I-86, 10" pipe being draw approx 900 feet under the highway. This pipe will act as the casing for the 6 or 8 inch pipe that will be carrying the sewage.

Pipe Draw operation under I-86.

Draw speed is about 1.5 feet per minute or about 10 hours to draw the approx 900 feet.

Pipe Draw Oberation under I-86.

Assembly of "Y" connections for connecting "Laterals" into the Main.

"Laterals" are the lines that will run from the pumps to the Mains.

The drill is underground running from the driver toward the camera. The truck provides the drilling "mud".

Small diameter coiled pipe for "Laterals".

Unloading more pipe, getting ready for the day.

Fully Restrained, Fused Joints

PolyPipe^{® HDPE pipe is joined by the butt fusion method conforming to ASTM D2657 and PolyPipe® recommendations. This process provides for a precision heat weld as strong as the pipe wall. A properly fused pipe eliminates root penetration, infiltration and exfiltration of the joint. The fusion bond also creates a fully restrained joint. The strength of the joint enhances the flexibility and resiliency of the whole line, permitting bending and flexing.}

The pipe prep/joiner is shown left of center. Pipe entering is on the right, the string leaving is on the left looped and headed for the hole. The hole is off to the lower left of the picture.

The pipe is laid and ready for drawing back through the drilled hole. The hole is in the distance next to where the men are standing.

This is the drilling head projecting from the drilled hole.

The drilling head is being removed for installation of the reamer used to enlarge the hole for pipe installation.

This shows the angled spade on the drill head which is the means for steering the drill rod. The "clock" of the head is controlled by the operator based on feed back from the locator.

The particular pipe being drawn bac through is 8"D. The reamer provides a hole large enough for the pipe.

Estimeate time to draw the 520 feet of pipe is 3 hours.

Since the pipe is plastic a wire is strung through the drilled hole along with the pipe to provide as a target for a locator device in the future.

Wire and pipe are shown at the entry hole.

10' long rods showing the tapered thread for joining the stems.

The "drilling fields" - On the right-hand side of 446 heading West just before reaching the WWT plant. The pipe prep station is in the foreground, the drilling operation is far in the background and to the left.

Pipe inventory, generator and pipe cutter and joint prep and joiner machine.

Business end of the pipe joiner showing the tail-end of the long pipe loop laid out on the field.

The "locator" monitors the progress of the head of the drill rod or "stem". He keeps the drill on line and at proper depth by advising the "operator" what angle or "clocking" to target the drill-head. Target depth here is to be below 5 feet. At the time of this picture the drill head was at 5 feet 6 inches deep. The engineer is monitoring progress.

The drilling unit in use. The rods or stems are driven into the earth using drilling "mud" as a cooling and lubrication medium. The mud is the pool of tan colored material around the drill stem.

The power driver and directional device.
