Cowan Group Engineering (CGE) performed multiple surveys for AECOM on Oklahoma City’s 60-inch water pipeline from Atoka Reservoir to Lake Stanley Draper. The initial survey included boundary and easement retracement along with topographical survey at each one of the major surge tank sites along the 100-mile long pipeline corridor stretching from Lake Stanley Draper to the Atoka Reservoir.

The second survey included boundary and easement retracement along with topographical survey at each one of the pump stations and minor surge tank sites along the same pipeline corridor.
