A study conducted by the Centre for Water Resources Development and Management (CWRDM) has cited unplanned and rapid construction and encroachment of waterbodies as a major reason for urban flooding in Kozhikode.
The study, conducted as part of the Water 4 Change (W4C) project jointly funded by the Department of Science Technology (Government of India) and the Dutch Research Council (NWO), is being conducted in three cities. It aims to develop an integrative, fit-for-purpose, and situated water-sensitive urban design framework for fast-growing, livable cities. Bhuj in Gujarat and Bhopal in Madhya Pradesh are the other two cities included in the project.
The study has pointed out that the loss of traditional knowledge, such as locally made temporary dams and practices like designated groves and ponds linked to hydrological processes and ecosystems, was affecting the maintenance of the water system. It also added that the shift from groundwater to external piped water as the primary source of drinking water had reduced the need to maintain and protect groundwater, leading to its contamination and making it unsuitable for consumption.
The report condemns the discharge of untreated wastewater from households and establishments directly into local waterbodies and highlights the inadequacy of the existing urban stormwater drainage system.
The report also proposed solutions to the major water-related issues identified. It advised the Kozhikode Corporation to invest in expanding and upgrading stormwater drainage systems to manage higher water volumes and to identify critical sections prone to flooding and disruption. It also suggested preserving or implementing green infrastructure solutions, such as traditional and communal practices, green roofs, permeable pavements, and rain gardens. Besides, it recommended recovering existing waterbodies and reviewing water management policies.
