Goa's Sal Barrage Nears Completion, Set to Transform Water Infrastructure
In a significant development for Goa's water management, the Sal barrage project is now 70% complete and is projected to become fully operational by May this year. This announcement was made by Dnyaneshwar Salelkar, the chief engineer of the state's water resources department (WRD), highlighting a major milestone in the region's infrastructure.
Enhanced Water Supply for Bardez Taluka
Once operational, the barrage will deliver an additional 250 million liters per day (MLD) of raw water to the state. This substantial increase is expected to primarily benefit Bardez taluka, addressing long-standing water scarcity issues. The additional water will be channeled to water treatment plants, thereby boosting the drinking water supply for the sub-district.
Project Details and Construction Timeline
The Sal barrage is being constructed on the Chapora river in Sal village, located within Bicholim taluka. With an estimated cost of around Rs 300 crore, the project has been under construction for nearly three years. This initiative marks a significant upgrade from the previous minor bandhara that existed over the Chapora at Bicholim, which was insufficient to meet the growing water demands.
Flood Prevention and Historical Context
A key benefit of the barrage is its role in flood mitigation. During the monsoon season, the Chapora river has historically breached its banks, leading to severe flooding. Notably, in July 2021, Sal village experienced its worst floods due to water release from the Tillari reservoir following heavy rainfall. The new barrage is designed to prevent such recurrences, ensuring better control over water levels and protecting local communities from flood-related damages.
Addressing Seasonal Water Shortages
The Sal project will also play a crucial role in meeting drinking water requirements, especially during the winter months. This period coincides with the annual maintenance of the Tillari reservoir canals, during which raw water supply to Goa is temporarily halted. The barrage will provide a reliable alternative source, mitigating shortages that have previously affected areas like Calangute and Guirim.
Additional Benefits and Infrastructure Impact
Beyond drinking water, the project will support irrigation along its route, covering more than 20 kilometers to the relevant water treatment plants. For most of the year, the Assonora treatment plant relies on water from the Tillari reservoir. The new barrage will supplement this supply, enhancing overall water security and reducing dependency on a single source.
In summary, the Sal barrage represents a transformative step for Goa's water infrastructure, promising improved supply, flood control, and resilience against seasonal shortages. Its completion by May is eagerly anticipated by residents and authorities alike.
