Sector 138 Noida: The water tanker reality nobody talks about

Just moved into my new flat in Sector 138, possession was in March. Things nobody told me: the water situation is messed up! Municipal water supply is completely unreliable. We're almost entirely dependent on water tankers. Builder promised 24x7 water, but it's a lie. They charge extra for the tanker, which is a total loot. It's costing me an extra ₹3000-4000 per month, on top of the maintenance charges! Matlab, what's the point of paying so much for maintenance if basic water isn't guaranteed? Anyone else facing this same issue? What did you guys do? Socha tha Noida mein life sahi hogi, but this is a headache.
