Sector 117 folks, water situation kya hai aapke yahan?

Just moved into Sector 117, and honestly, the water supply is a mess. Municipal water aata hi nahi regularly. We're totally dependent on borewell water, which isn't ideal, right? Builder promised 24x7 supply, but it's a lie. Anyone else facing this? Thinking of complaining to the RWA, but not sure if it'll help. Should I invest in a water purifier system? Koi idea hai, what to do?
