I determined the most suitable drilling point by carrying out a feasibility study according to the topography and geology of the region to be measured. • I created a stratigraphic map of the underground with a geological instrument that measures the groundwater level with geological and geophysical data.• I cooperated with subcontractor drilling companies to drill at the point I determined.• I decided on the drilling type (rotary or compressor) suitable for the rock structure of the region and followed the drilling activities.• I collected groundwater samples and sent them to the laboratory to examine whether the groundwater obtained was suitable for use.• According to the results from the laboratory, I determined the well design, the type and power of the pump to be used so that the well could be used in accordance with the regulations.• If customers wanted to store groundwater on the surface, I provided consultancy on the design of the storage and the appropriate materials to prevent water leakage.• I provided the groundwater certificate to the customers by reporting the field work, drilling work, laboratory results and costs carried out by my company.
