Atmospheric Corrosion
Avista’s Atmospheric Corrosion program monitors metallic pipelines for corrosion through regular inspections of meters that are settled, overgrown, overbuilt, or need protection like barricades.
Cross Bore
Avista’s Cross Bore program reduces risks from cross bores, where a gas line accidentally intersects a sewer or septic line. It uses camera technology before and after construction to check sewer lines for damage.
Isolated Steel
Isolated steel inspections are performed at the meter and service risers in order to identify sections of isolated steel pipeline, including any isolated service risers, within Avista's system.
Leak Survey
Avista’s Leak Survey program detects, classifies, and reports natural gas leaks in pipeline systems. It includes various leak survey methods, classification criteria, investigation steps, and record-keeping requirements.
