I cannot comment about other cities, Bengaluru it was a known issues. Primarily big builders who launch their projects dig up multiple borewell and pump out the groundwater. When government realized that ground water levels were getting depleted they did make rainwater harvesting mandatory. Yet it is either shoddily implemented or never implemented.

Most of the apartment complexes water supplies are provided by tankers. Local politicians have stake in these tanker services, so it is in their best interest to make sure local populace is dependent on the these tankers and not on government connections which is heavily backlogged.

Few societies, residents do get together invest their own money to get proper water harvesting, but that is far and few to even make a noticeable difference. Builders most of them flat out refuse to build robust water harvesting systems.

This is really insightful. Thank you. I had no idea so much was dependent on tanker trucks.
