City Sewer Line Replacement
This was a 200' run of a 4" SCH20 sewer line that had very little pitch and was crushed in three spots causing a major sewer back up in a small apartment building. To fix the problem we were able to hook up further down the line to gain the 2% pitch that we needed to make everything work as it should. The pipe was replaced with a 4" SDR 35.

Leach Field H2O Loading Pump Installation
This job was a major undertaking due to the septic tank bottom being 20 feet below the surface. This forced us to use double stacked trench boxes and various steel plates to keep the working area safe. We maintained an accident free work zone and kept the building in service for the entire length of the installations.
Lake Road Webster, NH
Full Sewer System Replacement
This property was a seasonal camp that we installed a complete new sewer system to make it usable on a year round basis. The system included a 1250/500 combo tank with a pump station in the 500 gallon side which pumped up to a large raised stone and pipe leach field. We chose to complete this project in the winter time due to the lake level being low at that time but unfortunately the ground water was still a major hurdle. Whole tree chips were used for the finish product as to keep as much of the original look as possible.

• Gould Road Warner, NH – November 2014
“Clean up was very good! They put up the clothes line, moved logs… in the pouring rain. We especially appreciated your extraordinary attention to detail and the respectful way you answered our questions and concerns. Your handling of a difficult job and the way you managed the situation with our neighbors was outstanding. Thank you so much. One of the things that Nate did that I will always appreciate was when I asked him about the “Out Take” pipe under the living room window you said it was not part of the job but when I voiced my concern you answered, “Then let’s do it!” I have told that story to many people who were wondering what the heck was going on at our house. Great attitude on your part Nate, and good business approach. Thanks again for a job well done. “
• Old Henniker Road Hopkinton, NH – 2014
"These two (Nate & Bruce) answered every question. Not only that, they were always in good moods no matter what the weather and difficult the work. They consulted us with move. They were never put out with us. We are extremely satisfied! These guys started work early, never took any breaks, and worked late to make sure everything was done . We have already told family and friends how pleased we are. They left our yard as beautiful as before. Our driveway is great! They did such a good job I feel I am able to call them with questions even now that the job is finished. They did a wonderful job hiding the vent pipes! It was obvious these guys are professionals. They were both so good at using the equipment they didn’t break anything. It was amazing to watch them maneuver the machinery. It was very reassuring to have the cell phone numbers. That was a very nice, professional touch. They not only worked hard, they worked safely… These men earned their pay!”
