Veligonda Project Phase I Inauguration and Krishna Water Release
Source:etvbharat ↗
Why It Matters
The Poola Subbaiah Veligonda Project is a crucial irrigation and drinking water lifeline for Southern Andhra Pradesh. Understanding its water source, engineering design (gravity-based tunnel system), and the specific drought-prone districts it benefits is vital for APPSC Group 1 Prelims questions on regional geography and infrastructure.
Summary
Andhra Pradesh Chief Minister N. Chandrababu Naidu inaugurated Phase-I of the Poola Subbaiah Veligonda Irrigation Project. The project is designed to draw Krishna River water from the Srisailam reservoir via gravity-driven tunnels into the Nallamala Sagar reservoir, bringing vital drinking and irrigation water to the drought-prone and fluoride-affected districts of Prakasam, Nellore, and Kadapa.
Key Points
- Andhra Pradesh Chief Minister N. Chandrababu Naidu inaugurated Phase-I of the long-awaited Poola Subbaiah Veligonda Irrigation Project, releasing 10.70 TMC of Krishna River water into the Nallamala Sagar reservoir.
- The gravity-based irrigation project draws water from the Srisailam reservoir on the Krishna River through giant tunnels to store it in the Nallamala Sagar reservoir.
- Phase-I aims to irrigate 1.19 lakh acres and supply drinking water to nearly 4 lakh people, while the fully completed project targets 4.47 lakh acres across 30 mandals in Prakasam, Nellore, and Kadapa districts.
- The project provides a critical solution to long-standing drought issues, groundwater depletion, and hazardous fluoride contamination in the Prakasam and surrounding regions.
Important Terms
Poola Subbaiah Veligonda Irrigation Project
A major gravity-fed water diversion project in Andhra Pradesh, channeling Krishna River water from Srisailam Reservoir into Nallamala Sagar to supply drought-prone and fluoride-affected districts.

Prelims Trap
The Veligonda Project is a major lift-irrigation scheme designed to pump water from the Srisailam reservoir.
It is a gravity-based water-conveyance system utilizing twin underground tunnels, completely avoiding the energy-intensive pumps typical of lift-irrigation schemes.
Static Concepts Connected
What are the key ecological features of the Nagarjunasagar-Srisailam Tiger Reserve (NSTR)?
- Geographical Area: Spans across five districts in Andhra Pradesh and Telangana, making it India's largest tiger reserve.
- River System: The Krishna River cuts through its basin, carving deep gorges such as the Srisailam gorge.
- Forest Type: Dominated by Nallamala Hills, featuring southern dry deciduous and dry evergreen scrub forests.
What is the cause and regional distribution of groundwater fluorosis in Andhra Pradesh?
- Geological Origin: Weathering of fluorine-bearing minerals (granites, gneisses) under arid/semi-arid conditions.
- Affected Belts: Prakasam, Guntur, and parts of Nellore are highly endemic, causing skeletal and dental fluorosis.
- Mitigation Strategy: Shifting from contaminated aquifers to gravity-fed surface water systems (like Krishna or Godavari).
Cross-Topic Patterns
Infrastructure vs. Tiger Conservation
Balancing mega-irrigation projects with wildlife protection, where advanced tunneling (TBMs) is used under protected areas like NSTR to bypass traditional surface environmental disruptions.
Fluoride Mitigation & Public Health
Linking water-resource engineering directly to rural health outcomes in Prakasam, substituting fluoride-contaminated groundwater with treated gravity-fed surface water.
APPSC will likely test Veligonda's unique features—its gravity-run design, Srisailam source, and passage under the NSTR tiger reserve.
