The S.C.A.F pipeline encountered by Isaac Clarke and John Carver following their crash-landing on Tau Volantis was (presumably) one of many constructed by the S.C.A.F on Tau Volantis to supply Facility One. Due to 200 years of exposure to the elements, the pipeline has broken apart in many places and is no longer filled with anything (it is unknown what the pipeline was used to transport, but the design is similar to that of oil pipelines).
