Sector 129: Good investment, but water is the real issue.

I work in real estate, and even I'm confused about Sector 129. Investment-wise, seems decent ROI in 3-5 years, especially near Advant Navis Business Park. But off the record, water supply is a big worry. Heard Reliance Humsafar residents are mostly tanker-dependent. Is it true? Should I buy here knowing I'll be paying extra for water every month? Has anyone else faced this? Any tips?
