Signature Global Park 1: Power backup and water supply reality check needed

Signature Global Park 1 ki full power backup wali baat toh bas sunne mein achhi lagti hai, pata nahi kitni sach hai. My parents keep saying check everything twice. Actual residents, please batao, is it full flat backup ya sirf common areas? Aur paani ka kya scene hai? Tanker dependency kitni rehti hai? Ab samajh nahi aa raha, first home hai yaar.
