Mohali investors: Investor Avenue utility reliability - what's the ground reality?

Did a site visit to Investor Avenue Luxury Floor 3 on Saturday and honestly, I'm a bit confused about something. They're promising full power backup but I've heard stories about other Mohali projects only giving backup for common areas. For an investment property, uninterrupted power and reliable water supply are huge for tenants, right? Kya kisi ko actual experience hai? Tanker dependency kitni rehti hai? I don't want future tenants complaining. Does this affect resale value much? Not sure agar yeh chhote details baad mein bade issues ban jaate hain.
