Jaypee Krescent Homes: Power backup and water reality?

Noida mein property dekh raha hoon, especially Jaypee Krescent Homes. Builders toh bohot kuch promise karte hain, but I'm really worried about daily utilities. Parents bolte hain power backup aur paani ka issue bohot common hai societies mein. Builder toh full flat backup bol raha hai, but real-life mein kitna sach hai? Yaar, common areas tak hi milta hai kya mostly? Aur water supply, tank capacity kitni hoti hai? Subah-subah pressure sahi aata hai ya tanker mangwana padta hai? Pehla ghar hai, toh choti choti cheezein bhi tension de rahi hain. Experienced log batao, ye sab check kaise karein site visit pe? Jaypee Krescent Homes mein actual experience kaisa hai in terms of daily utility services? Kya trust kar sakte hain promises pe?
