A contractor who knows an independent expert is on site drills a very different borehole than one who operates unsupervised. Inflated metre counts, undersize casing, skipped development, misrepresented yield tests — all almost impossible to catch after the fact without specialist equipment on site during the work.
What Contractor Overseeing Covers
- Pre-drill review — verify the proposed drill point and review the quote
- On-site supervision — depth, casing and drilling method verified in real time
- Development monitoring — borehole flushing time verified
- Independent yield test — contractor can't misrepresent flow rate
- Water quality sampling — independent sample sent to certified lab
- Documentation check — WRC certificate, borehole log reviewed
