Sloping sites and changing grades

Where a street or a lot slopes steeply, underground lines have to deal with elevation changes. Gravity sewers and storm pipes need a continuous fall, which on a steep site may mean deep cuts at one end and shallow ones at the other, or structures that drop the flow in steps. Water lines can follow the slope but may need valves at high and low points as the owner's specification requires.

Work on sloping sites asks for some extra care:

• trenches are supported or benched for their depth, and equipment is positioned safely on the grade;
• spoil and runoff are managed so that they do not wash downhill into the street or onto neighbors;
• existing lines are confirmed with hydro excavation, especially where several utilities share a narrow corridor;
• directional drilling may carry a line beneath a steep bank, steps or a retaining wall;
• restoration includes stabilizing the disturbed slope.

On flatter sites, the work follows the familiar pattern of locating, excavating or drilling, installing and restoring.

In Duluth, we work for homeowners, businesses, industrial owners and public owners.
