Annual Walking and Mobile Gas Leak Survey In Progress
This week, the City of Palo Alto Utilities (CPAU) will begin its annual mobile and walking gas leak detection survey of the City. This annual, routine safety check is conducted every year as required by Department of Transportation Pipeline Safety Regulations, and is carried out to ensure the safety of all who live and work in Palo Alto. Approximately one-half of the City is covered every year so that the entire City gas service system can be reviewed in a two year period. The 2016 survey began on April 25 and should be finished by September.
City contractor, Manesco Corporation, will walk residential areas to check for gas leaks along pipes, gas meters and covers. See map of walking survey area below. The business districts will be surveyed with a moving vehicle canvassing natural gas service points, mains and meters. The mobile survey includes atmospheric tests near gas mains, in utility manholes, at pavement and sidewalk cracks, and other locations in which it is possible to identify gas leaks.
In the end, over 200 miles of gas main pipeline will be checked through this thorough review! If any gas leaks are found, they are documented and repaired according to CPAU’s policies.
If a customer’s meter is inaccessible, the surveyor will leave a door hanger asking them to contact CPAU to schedule a time for Manesco to return and complete the survey. Customers are asked to call our Gas Utility Operations for non-emergencies at (650) 496-6940 Monday through Thursday, 6:30 a.m. to 4 p.m., or (650) 496-6982 on Fridays, from 6:30 a.m. to 3 p.m. As a reminder, all City contractors and surveyors carry CPAU identification cards.
