It is easy to lay a pipe in the ground. But that pipe, when covered with dirt and hidden from view, must last for a century. Achieving that result requires advanced technology, like laser projectors that plot elevation lines on distance markers, and nuclear gauges that measure soil moisture and density.

Every year, Crestline’s underground crews lay miles of pipe-ranging from one inch to 108 inches in diameter for water lines, sanitary sewers and storm sewers. Related structures such as intakes, detention systems, box culverts and pump stations are routinely installed as well.
