Dowleswaram Barrage set for modernisation

Metro India News | AMARAVATI

In a significant move aimed at strengthening irrigation infrastructure in the Godavari delta region, the Andhra Pradesh government has initiated the long-awaited modernisation of the historic Dhavaleswaram Barrage, popularly known as the Sir Arthur Cotton Barrage. Considered the lifeline of the Godavari delta districts, the iconic structure is set to undergo a comprehensive upgrade nearly 46 years after its last major modernisation.

Built by legendary British engineer Sir Arthur Cotton, the barrage has played a pivotal role in transforming the Godavari region into one of the most fertile agricultural belts in the country. However, decades of continuous operation have resulted in the deterioration of several key components, prompting concerns over the structure’s long-term safety and operational efficiency.

The last major modifications to the barrage were undertaken in 1980. Since then, experts and technical committees have repeatedly highlighted the need for extensive repairs and modernisation, particularly due to the deteriorating condition of the barrage gates. Of the barrage’s 117 gates, many have suffered severe corrosion over the years, raising concerns about their reliability and safety during flood management operations.

Responding to these concerns, the state government moved forward with a large-scale modernisation programme. Initially estimated at around Rs 150 crore, the project attracted bids from several firms. Following the tendering process, engineering company Becam secured the contract with a bid value of Rs 124.34 crore.

As part of the project, all 117 ageing and rusted gates will be removed and replaced with new technologically advanced gates designed to improve operational efficiency, safety and water management capabilities. The upgrade is expected to significantly enhance the barrage’s ability to regulate water storage and discharge, particularly during flood seasons and periods of high river inflows.

Officials have set a target of completing the modernisation works within the next two years. Once completed, the upgraded infrastructure is expected to strengthen irrigation security for lakhs of acres of agricultural land across the East and West Godavari districts. The project is also expected to improve the long-term sustainability of water resources management in the region, benefiting farmers and supporting agricultural productivity.

The Dhavaleswaram Barrage remains one of the most important irrigation structures in Andhra Pradesh, and its modernisation is being viewed as a crucial investment in the state’s agricultural future. Field-level works are expected to commence shortly after the completion of all remaining administrative and technical formalities.
