NW Natural System Integrity Program
We hold ourselves to the highest standards of design, construction, inspection, maintenance and repair, and developed a System Integrity Program in support of this commitment. Here's what we've accomplished:
- Replaced all cast iron and bare steel pipes with modern coated steel and polyethylene to improve pipeline reliability and reduce corrosion.
- Exceeded federal inspection regulations.
- Reduced damages caused by dig-ins through a prevention program.
- Increased effectiveness of our quality assurance program.
- Invested in technology that tracks changes in the system for early detection.
