The 72 in. dia. North Coast Superaqueduct carries water 70 km from Arecibo to San Juan. Just after construction, the aqueduct experienced failure of two pipe segments during a transient pressure event caused by sudden closure of a valve. SGH investigated the cause of failure and assessed the condition of the entire pipeline.
