Eta II monsoon reality check: Don't trust the brochures

My two years in this Eta II society have been a complete reality check about monsoon issues. I work in real estate, but honestly, even I didn't anticipate the waterlogging after heavy baarish here. Basement parking pura bhar jaata hai, aur roads pe toh boats chalani padti hain. Society RWA bhi kuch khaas nahi kar rahi drainage ke liye, bas maintenance charge badha dete hain. Builders marketing mein sab smooth dikhate hain, but ground reality alag hai. Anyone else in Eta II facing this same issue? Kya solutions nikale aap logon ne?
