Earthquake-Proof Pipes

Truckee Meadows Water Authority (TMWA), in Reno, NV replaced a 100-year old wooden flume damaged by a 4.7 magnitude earthquake with high-density polyethylene pipe (HDPE).

Just like surgeons doing a coronary bypass operation, engineers and construction crews saved a patient using high-density polyethylene pipe (HDPE) pipe as the replacement pathway. In this case, the patient was a 100-year old wooden flume that was the main source of potable water for the Reno, Nev., community. The catastrophic event was a 4.7-magnitude earthquake that led to the failure of a 200-ft run of the elevated flume that followed along a steep hillside slope located immediately above a residential subdivision.
