Earlier this year, Brownline Canada surveyed two horizontal directional drills in Mildred Lake, Alberta. Our client Directional Drilling was tasked with the trenchless relocation of a sanitary sewer line.
The new sewer line was installed under wetlands and a highway. Surface access was very limited, so the job required a guidance system that does not rely on measurements taken from the surface above the bore line. Brownline's Drillguide GST works independently of its surroundings, which made it the ideal system to steer these pilot drills to the exit stake. 🧭
The result? Two highly accurate and efficient crossings, a smooth installation of the sanitary sewer line, and a satisfied client. 🎯
