During the 2026 monsoon, Karnataka recorded a sharp drop in rainfall, intensifying pressure on rural drinking‑water supplies. The Rural Drinking Water and Sanitation Department has classified 1,119 villages as vulnerable, including 22 problematic zones within Bengaluru Urban.

Contingency Plan Overview

To guarantee uninterrupted supply through September, the department crafted a village‑wise contingency strategy that mobilises 978 private borewells, 254 private tankers, and an additional 35 departmental tankers. Private borewells alone are projected to serve 838 villages, because where reliable groundwater exists, borewells provide a more sustainable and cost‑effective solution than tanker transport.

District‑wise Vulnerability Mapping

Using detailed mapping of villages and gram panchayats, the agency determined the required number of government tankers. Bidar emerges as the most at‑risk district, with 93 villages across 65 gram panchayats flagged. Bengaluru South and Shivamogga follow, while Vijayapura, Kodagu and Gadag show the least vulnerability, albeit with a few gram panchayats earmarked for intervention.

Financial Commitment and Rates

In Bidar, seven private tankers and eight private borewells will service nine vulnerable villages. The state has already sanctioned ₹117 crore for scarcity mitigation. Hiring rates for private borewells—set by district administrations based on water yield—generally range between ₹10,000 and ₹15,000 per month.

Outlook and Monsoon Forecast

The current monsoon deficit, at 28 % below normal, is largely attributed to a delayed southwest monsoon triggered by a strong El Niño. Between June 1‑8, the state recorded only 191 mm of rain against the expected 266 mm. Although July showed a modest rebound, officials have extended the contingency plan through September, anticipating improved water availability as the monsoon progresses.
