The NDA government has completed the Polavaram Left Canal in record time. This strategic infrastructure will now deliver Godavari floodwaters to millions of acres of farmland and quench the thirst of lakhs of residents in North Andhra.

  • Polavaram Left Canal completed within a 26-month timeframe.
  • Water will be delivered to Anakapalli district and North Andhra regions.
  • Complex engineering involving aqueducts and siphons across 4 rivers.
  • Benefiting 5.23 lakh people with drinking water and stabilizing lakhs of acres of irrigation.

In a significant boost to the agricultural and domestic water security of Andhra Pradesh, the NDA government has successfully completed the construction of the Polavaram Left Canal. This massive undertaking ensures that the floodwaters of the Godavari river are diverted to the arid regions of North Andhra, marking a turning point for the local economy.

The project spans 213 kilometers from the main Polavaram dam area at Nelakota. The construction was not a simple excavation; it required cutting through the rugged terrain of the Eastern Ghats. Engineers had to carve through hills reaching heights of 107 meters, reducing them to 28 meters to ensure a gravity-based flow of water.

Overcoming Engineering Hurdles

The canal's path required crossing four major rivers: Aleru, Pampa, Tandava, and Varaha. At the Pampa river, a sophisticated aqueduct was built using 312 Z-sheet piles driven 100 meters deep into the riverbed to prevent seepage. The Tandava river crossing features a 447-meter-long aqueduct with a capacity of 10,634 cusecs.

To manage the Aleru river, a siphon was constructed, allowing the main canal to pass beneath the riverbed while the Aleru river continues its natural course above. Furthermore, legal disputes regarding the Varaha river crossing were resolved swiftly, with critical pillars and slabs completed in just 45 days under new contractors.

Why This Matters

BozokMedia analysis shows that the completion of the Polavaram Left Canal is more than just an irrigation project; it is a strategic socio-economic intervention. By stabilizing water supply for over 2 lakh acres of land and providing drinking water to 143 villages, the government is effectively mitigating rural distress and enhancing food security in the region.

The integration of multi-river aqueducts and the piercing of the Eastern Ghats makes this one of the most challenging irrigation feats in Southern India.

The impact will be immediate. Chief Minister Chandrababu Naidu is set to release 5,000 cusecs of water. This will fill 110 tanks under the Pushkara lift irrigation scheme and stabilize irrigation for 1.48 lakh acres, 80,700 acres under Aleru, and 12,000 acres under Pampa.

Did You Know?: The canal intersects the Kolkata-Chennai National Highway at 9 different points, requiring the construction of massive bridges and traffic diversions to maintain connectivity.
