The Kochi Corporation is set to begin Geographic Information System (GIS)-based mapping of its stormwater drainage network under the Centre’s Atal Mission for Rejuvenation and Urban Transformation (AMRUT) scheme, to improve urban flood management and drainage planning across the city.
The civic body has invited bids for the project. This involves mapping existing drains, identifying missing links in the network and preparing a detailed drainage database for future infrastructure planning.
The initiative comes at a time when Kochi continues to face recurring waterlogging during heavy rainfall spells associated with the monsoon and tidal influences.

Kochi GIS Mapping for Drainage Audit and Flood Management
According to officials, the GIS-based survey will digitally map canals, drains, culverts and connected stormwater infrastructure across the corporation’s limits. The project is expected to help authorities identify choke points, encroachments and weak drainage stretches that contribute to urban flooding.
The work will be carried out under the AMRUT scheme, which focuses on urban infrastructure upgrades, including water supply, sewerage and stormwater drainage systems in Indian cities.
The selected agency will conduct field surveys and prepare spatial data layers for integration into the city’s planning systems. Officials said the data would support future drainage expansion projects and maintenance planning.
Urban planners have increasingly pushed for GIS-driven infrastructure monitoring to improve resilience and disaster preparedness.

Digital Urban Infrastructure Gains Momentum
The Kochi project signals a broader push by Indian urban local bodies to use geospatial technologies for infrastructure management and climate adaptation planning. GIS-based mapping is increasingly being adopted for utilities, sanitation networks and mobility systems under Smart Cities and AMRUT-linked projects.
Experts say digitised drainage mapping can improve response time during extreme weather events and support data-backed urban planning decisions. It also enables authorities to monitor illegal construction, blocked waterways and gaps in drainage connectivity more efficiently.
The move comes at a time when several Indian cities are strengthening flood mitigation strategies amid rising concerns around climate-linked urban flooding, rapid construction and inadequate drainage infrastructure. With India pushing for digital governance and sustainable development, precision GIS mapping of commons is likely to become a policy priority.
