Residents of Mannur Vadakkumpad in Kadalundi, Kozhikode, are grappling with severe seawater intrusion due to the failure of the Attumkunnatthu regulator. High tides push saline water into homes and wells, creating stagnant cesspools and acute freshwater shortages.
The Attumkunnatthu regulator, locally called Chirppu, was built just a year ago to direct monsoon rainwater into the Vadakkumpad River while blocking seawater during summer. Authorities have not closed its bund despite available planks nearby, allowing strong tidal inflows to spill into residential compounds. This oversight has worsened the crisis, with saline water now spreading to nearby Mecheri Padanna and Kodappuram canal regulators, threatening more communities.
Whenever high tides hit the Vadakkumpad River, seawater floods low-lying coastal areas, turning homes into waterlogged zones. Contaminated wells have left families without potable water, forcing reliance on distant sources amid summer heat. Locals report repeated warnings to panchayat officials went unheeded, leading to this preventable hardship.
Kozhikode’s coastal regions have long battled saline intrusion, especially in summer when groundwater depletes and sea levels rise with tides. Similar issues plague areas like Vadakara and Payyoli, where river and canal salinity contaminates wells, echoing Kadalundi’s plight. Studies highlight the Kadalundi River Basin’s vulnerability to such groundwater threats due to over-extraction and poor recharge.
These structures act as barriers, channeling fresh water in monsoons and sealing against saline advances in dry seasons. Failures, like at Attumkunnatthu, mirror statewide problems dilapidated regulators in places like Vembanad Lake allow tides to overwhelm farmlands and homes. In Kozhikode, past saline creeps into rivers like Kuttiady have disrupted drinking supplies, underscoring the need for proactive maintenance. Residents demand immediate bund closure using on-site planks and long-term upgrades to prevent recurrence. Panchayat and irrigation departments must prioritize inspections and repairs, as delays amplify health risks from contaminated water. Community-led monitoring could bridge gaps until officials act, ensuring Kadalundi’s coasts stay livable.
