See, All India Institute of Medical Sciences or AIIMS are centrally funded institutes and are provided with all the modern amenities and the students there spend a lavish time with all the best infrastructure of the country. So, as a result, the water quality of AIIMS Bhatinda is of top notch quality and is regularly checked and monitored and you don't need to take any tension about it as it's perfectly safe.

Hope I have answered your question. All the best!
