Shiv Krishna Valley: Post-possession snag list reality?

Are snag lists after possession in Noida projects actually taken seriously by builders? Kids toh ab nikal gaye, so I'm thinking of selling our big house and moving to a smaller, manageable flat, maybe in Shiv Krishna Valley. Visited a few places, brochure mein sab accha lagta hai. But I'm worried about the real construction quality once you move in. Friends have told me about seepage issues, fittings breaking within months. Also, water supply ka kya scene hai? Don't want to depend on tankers daily, especially with health issues. Is full-time, reliable water supply standard ya it's a constant struggle? Any experiences with builders actually fixing post-possession issues promptly? Ya fir sab bas promises hi hain?
