Residual natural gas trapped in the ground after the repair of a distribution-system leak can be a headache for utility employees and customers. The pump truck, a unique approach to removing residual gas, is described in this paper. Natural gas is lighter than air and naturally tends to rise upward and dissipate in the atmosphere. However, pavement, buildings or soil conditions around a leaking pipe often cause gas to be trapped in the ground. In addition to removing trapped gas, the pump truck is used to help pinpoint leaks where the source is difficult to locate because of soil conditions.
