Step 1: Recognise this as a statutory hygiene requirement.
Mine safety regulations lay down minimum separation distances between drinking water points and sanitation facilities purely to prevent contamination of the water supply.
Step 2: Recall the specific rule.
Under the Mines Rules, 1955, Rule 31 which governs the provision of drinking water at mines, the stipulated minimum separation from any washing place, urinal, or latrine is fixed at a clear distance so that no seepage or splash can reach the drinking water source.
Step 3: Pin down the exact figure.
That minimum distance specified in the rule is six metres, unless the Chief Inspector approves a shorter distance in writing for a specific site.
Step 4: Conclude.
So the drinking water point must be kept at least 6 metres away from urinals, latrines, and washing places.
\[ \boxed{6\text{m}} \]
