Sector 156 Noida: Thinking of buying, need real talk

Sector 156 mein soch raha hu property lene ka. I work in real estate but buying for myself is different. How's the water situation, specifically? Heard mixed reviews. Also, what about the commute? Metro connectivity sahi hai kya? Investment potential bhi dekhna hai, 3-5 saal mein ROI kya rahega?
