ABSTRACT
The need for accurate positions of facilities beneath earth’s surface can never be overemphasized. Detail survey which seeks to record the finished or the existing planimetric features in a piece of land has been utilized over the years for several purposes. The purpose of this study is to map sub – surface water pipelines at New Haven, Enugu North Local Government Area, Enugu State using modern survey techniques. This survey was required for the purposes of knowing the précised position (x, y coordinates) of the water facilities existed beneath the surface of the earth within the area study. This study integrated the use of Geographic Information System, Global Positioning System, Autocad software and aerial photograph of 15cm resolution during data acquisition and processing. The final plan production was done at a scale 1:10,000.
