Underground Pipe Location - Geophysics Or Surveying

Surveys for the detection of underground pipes are a statutory requirement in the United<br>Kingdom (UK) in the construction and water supply industries. The volume of surveys<br>undertaken suggests that this is a multi-million dollar operation with surveys being<br>undertaken by surveyors rather than geophysicists. The reasons for this approach are<br>examined and the problems associated with the detection of underground pipes with<br>geophysical methods are discussed.
