According to Hindu religious lord Varun is the god of water. We receive water by his liberality. You might see that digging tubewell sometimes water doesn’t come through it in very small quantity. This is the reason why tubewell is rooted out and re-established. Sometimes ponds do not have water or water might be bitter, thus it is not suitable for drinking purposes.

So, astrology provides muhurta for digging tubewell to avoid this situation. Digging Tubewell is the most important thing considered in the Vastu Shastra, it should be done in the most auspicious muhrat. These all listed below criteria should be checked for doing this: -

Nakshatra: - Uttaraphalguni, Uttaraashada, Uttarabhadrapada, Rohini, Adomukhi Nakshatra- Moola, Ashlesha, Vishakha, Krittika, Poorva Phalguni, Poorvaashadha, Poorvabhadrapada, Bharani and Magha Nakshatras are the most favorable nakshtras. All these nakshatras are descending looking and favorable for digging up for water.

Strong Ascendant: - The most important starting point is ascendant. This is a good muhurat for a job like a tubewell. This is very important to ensure that there are no issues.
