A condition assessment helps to understand the state of the prestressing wire which provides the pipe’s strength. PCCP manufactured during the 1970s is prone to low ductility in the wire and susceptibility to hydrogen embrittlement, both of which increase the risk of failure. Worn PCCP can rupture with no warning, potentially shutting down the entire facility.

During an inspection, it became clear that one major culvert – 140 feet long, 15 feet tall and running under heavily traveled Route 30 – had outlived its expected life. The 10-guage corrugated steel structure was deteriorated and needed to be repaired – with as little disruption to Route 30 traffic patterns as possible.

Tasked with transferring water from settling ponds to a frac pond for project in mid-Western U.S., a specialist water provider to oil and gas drilling companies needed a pump capable of handling a complex operation through a seven-mile-long steel pipeline.

The estimated flow through this regulator was 85 MGD, with a combined plant capacity of 170 MGD. Local environmental regulations restricted the use of diesel engines to 175 HP or less, and all engine driven equipment was required to be sound attenuated to 50 decibels at 30 feet.

Xylem built a coal ash disposal solution that met regulatory requirements while controlling labor and fuel costs.
