Prior to drilling, digging, trenching, and excavating, it is essential to know where underground utility lines are located. It’s particularly important for gas stations. Unlike residential house and office building properties, gas stations usually contain extra underground utilities including those for gasoline/diesel tanks and pumping systems. Besides the usual utilities including electrical power, communication, sewer, water and natural gas lines, there are other important lines such as fuel/product lines, ventilation lines and electrical conduits for the gasoline/diesel fueling system. There could also be other lines related to car shop and car wash facilities which are often found in gas stations. These underground utility lines can be either metallic or PVC. Ground penetrating radar (GPR) is a great tool Enviroprobe employs to locate both types of underground utility lines.
nviroprobe geophysicists and geophysical technicians have been tasked with locating underground utilities at hundreds of gas stations, often as part of Phase II Environmental Site Assessments. Besides precision locating equipments and GPRs, metal detectors or magnetic locators are also often used for undocumented underground storage tanks (USTs) which are not uncommon in gas stations.
