HDMC works on storm water management plan
Hubballi: The Hubballi-Dharwad Municipal Corporation (HDMC) is crafting a comprehensive storm water management plan, drawing lessons from recent urban flooding. Officials have mapped and categorised water channels, including over 290km of nalas and subnalas across the twin cities.
A detailed GIS survey and aerial mapping were completed. The corporation is now awaiting the Digital Elevation Model (DEM) report, which will provide crucial data for targeted reinforcement works and drainage upgrades.
This model will provide crucial topographical data, helping officials understand the natural water flow patterns and identify critical points that need immediate intervention. The DEM survey will complement the existing GIS aerial survey data, offering a complete picture of the drainage network.
The corporation plans to implement modern engineering solutions to prevent future flooding. This includes widening crucial drainage channels, constructing new stormwater drains, and installing advanced water flow monitoring systems. The officials are also focusing on removing encroachments along the natural water channels to ensure smooth water flow during heavy rainfall.
Additionally, the HDMC is planning to create water retention zones and improve existing drainage infrastructure.
These measures will help manage excess water during the monsoon season and reduce the risk of urban flooding. The corporation is also considering the implementation of sustainable drainage systems that can effectively handle increasing rainfall intensity due to climate change.
Once the DEM report is available, the HDMC will prioritise areas based on their vulnerability to flooding and begin implementing these solutions systematically.
The comprehensive approach aims to create a resilient storm water management system that can protect both residents and infrastructure from future flood-related challenges.
According to HDMC sources, following the recent unprecedented rainfall in Hubballi city that was 400 times higher than normal in a single day, senior HDMC officials are developing strategies to address future flood-like situations caused by downpours.
The officials will draft proposals and present them to elected representatives to secure special funding for implementing these measures on the ground.
Vijay Kumar R, superintending engineer, HDMC, explained that currently they possess information about subnalas from a survey conducted by HDMC officials, which indicates 29km of subnalas with a width exceeding 1.5m. He mentioned they are coordinating with the agency that completed the aerial survey for the DEM report, and once received, it would provide precise details about storm water sources and feeders to the subnalas.

Hubballi faces recurring flood management challenges
Hubballi: The Hubballi-Dharwad Municipal Corporation seems to have disregarded the lessons from the floods of 2019 in Hubballi, which caused extensive damage to roads and both private and public properties. A survey conducted following the 2019 floods in Hubballi, triggered by heavy rainfall, identified several critical issues: encroachment of nalas, lack of open drainage systems in commercial and residential zones, and clogged nalas. These identical problems have resurfaced now, as the city faces another flood-like situation. Meanwhile, HDMC continues to grapple with flood management issues. Despite the severe flooding in 2019, the essential preventive measures were not implemented effectively. The uncleaned nalas remain a persistent problem, causing waterlogging during heavy rainfall. Most of the residential and commercial areas have been particularly affected due to poor drainage systems. Local residents have expressed concerns about the lack of proper stormwater channels and the slow pace of nala retaining wall construction projects. The commercial areas along Koppikar Road, Dajibanpeth, Station Road, and others face similar challenges with inadequate drainage infrastructure. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Free P2,000 GCash eGift UnionBank Credit Card Apply Now Undo The corporation's failure to address encroachments along natural water channels has worsened the situation. Several buildings and temporary structures continue to obstruct the natural flow of water. The absence of proper drainage networks in newly developed areas has added to the problem. The civic body needs to implement a comprehensive flood management plan. This should include regular cleaning of nalas, removal of encroachments, and construction of proper drainage systems. The corporation must also ensure that new developments include adequate drainage infrastructure. Local authorities need to work with urban planners to develop long-term solutions. R Vijay Kumar, Superintending Engineer of HDMC, explained that while the Smart City Mission's green mobility corridor work continues, areas with constructed retaining walls along nalas have remained safe from flooding. However, Old Hubballi regions lacking these protective walls have experienced flooding issues. He noted that they identified the primary flooding causes in Old Hubballi and surrounding areas. Recently, MLA Prasad Abbayya, DC Divya Prabhu, and the HDMC Commissioner advised NHAI officials to remove the low-level bridges at Nekar Nagar, as these structures cause rainwater blockage, leading to flooding in residential and other areas. He further stated that several flood prevention strategies were developed and will be implemented.

Landslide on NH-169, waterlogging in Mangaluru as heavy rains lash coastal Karnataka
Heavy rains across Karnataka disrupted daily life on Sunday, with a landslide near Kettikallu in Belthangady taluk affecting vehicular movement along the busy National Highway-169. The downpour triggered widespread waterlogging and caused damage to infrastructure in several parts of the state, particularly coastal Karnataka. Also Read - Karnataka's Hubballi man caught dancing obscenely in public for Instagram reel gets lesson from police The India Meteorological Department (IMD) recorded intense rainfall in Dakshina Kannada, with Mangaluru receiving 170 mm and the Panambur observatory reporting 210 mm of rain in 24 hours. Neighbouring Udupi district received about 50 mm. An orange alert was issued for Dakshina Kannada, Udupi, Shivamogga, Chikkamagaluru, and Kodagu, warning of thunderstorms and lightning. In Mangaluru city, several low-lying areas such as Pumpwell, Kaikamba, Kankanady, and Bikarnakatte were severely affected by flooding. Residents reported rainwater entering homes, shops, and roadways due to poor drainage systems. The flooding in Pumpwell — a major traffic junction — led to slow-moving traffic, with buses from Bengaluru forced to reroute via Nanthur Circle after a diversion at Padil.

Locals alleged that despite repeated complaints, the Mangaluru City Corporation (MCC) has failed to implement lasting solutions. Emergency teams have now been deployed to clear blocked drains and monitor flood-prone zones. In Belthangady taluk, the landslide near Kettikallu caused a portion of NH-169 to be blocked. While no casualties were reported, clearing operations are underway to restore traffic on the vital route. Meanwhile, the Krishna River in Yadgir district has risen following heavy rainfall in Maharashtra, adding to concerns in the northern part of the state. Citizens and civic groups have urged the government to move beyond temporary fixes and take up long-term flood mitigation measures, including regular desilting of drains and building efficient rainwater channels to cope with recurring monsoon challenges.
