Directional Drilling
Directional Drilling is the most accurate method used to control underground installations. We use a specially designed drilling machine, along with environmentally safe drilling fluids in all our operations. By making a single drill hole in the ground, and using sophisticated locating equipment, the progress of the drill head can be monitored from above the ground. The drill head is in constant communication with the drill rig and provides us with the ability to adjust the direction of the drill head as it moves along the proposed path. The initial drill hole, for example, can be located outside of a wetland border and electronically guided so that the only disturbance to the wetlands would be by the operator of the hand held locator equipment following the progress of the drill head while walking through the wetlands. We have installed pipelines using this technology to cross under a river, under wetland areas, under roads and highways, and many other applications. In the Fall of 1998, we successfully used our directional drilling equipment to install 600' of sewer line under the Shawsheen River from the Tewksbury Townhouse Condo's to the Arlington Street sewer main.
The photo below shows an example of a typical installation of a pipeline under a busy street. Without this technology the street would have to be torn up, traffic interrupted and a police officer hired for safety. The use of this technology is so clean and "green" that traffic and the surface of the street were never disturbed. And, we left no bump in the road like the "patch" that would have been left after digging traditional open trench. Dust, blowing dirt and noise were kept to a minimum and we were only on-site for a matter of hours instead of days.
Here are a few pictures of a new laundromat that hired us to install about 220 feet of 2 inch copper fresh water pipe from the city water main to the water meter in their utility room.
We had all the existing utilities marked by "Dig Safe" and marked our drill head locations along the proposed path of the new water line.
We entered the ground from across the street so that we could drill down and pass a few inches over the city water main enroute to the laundromat. As you can see in the picture there was no large trench and no dirty mess to clean up.
If you look closely you can see our chalk mark on the floor indicating to the sensor exactly where the drill head should be. There was no other indication that any underground work was going on.
This is the hole that we dug in the little utility room where we expected the drill head to emerge. We were right on target again! At this point the drill head was removed and the copper pipe was attached and pulled back across the street to the water main by our drill rig.
We opened the road for about 4 hours to connect the new line to the water main. Traffic was only minimally interrupted for a short time rather than for two or three days using the open trench method.
