Water used to ghusl wash the Kabba

Salaams, with the blessign of Allah I have just returned from Hajj, a magical lifetime experiance! (May Allah accept all our hajj`s and dua`s) While in Hajj I was given some water by a friend who works at the haram grand mosque Makkah, This water I was told was used to bath the Kabba sharif this year during Hajj? I want to know if and how is it best for me to use this water? is there any value and blessing in this water and how can I benifit from these?

Regards
