HDMC works on storm water management plan
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.

Punjab minister reviews arrangements to deal with potential floods
Chandigarh, Jul 29 (PTI) Punjab Water Resources Minister Barinder Kumar Goyal on Tuesday reviewed the arrangements made by his department to deal with any potential floods. He said the government has completed the cleaning of the state's drainage systems and strengthened embankments to tackle any flood-like situation. Many parts of Punjab have received moderate to heavy rain in recent days. Goyal said the state government has completed 1,220 projects worth Rs 276 crore to tackle any potential flood situation. These include river revetment work, installation of studs, strengthening operations and desilting of drains. Additionally, 600 check dams have been constructed and 1,104 more are under construction. Besides, 3,905 soak pits are being created, over 53,400 bamboo saplings have been planted and 226 kilometres of vetiver grass has been cultivated. Vetiver grass is used for erosion control. Goyal said that out of the 850 drains, 601 required cleaning this year, which has been completed. So far, 4,766 kilometres of drains have been cleaned. Goyal said the Water Resources Department has implemented several strategic measures to handle emergencies, including the procurement of 8.76 lakh sandbags. Of these, 3.24 lakh sandbags have been filled and kept ready. For rapid response during emergencies, locations of sandbags have been uploaded onto the Geographic Information System (GIS), he said. For the first time, the minister said, the department has purchased 10,300 jumbo bags to enable quick breach filling. Goyal said water levels in all major dams in the state are within the safe limit and there is no cause for concern. The Bhakra dam currently stands at 1,618.38 feet, which corresponds to the average requirement of the past 20 years. The dam has a maximum capacity of 1,680 feet and is currently 47 feet below the 2023 flood level, he said. The Pong dam, which has a maximum capacity of 1,390 feet, stands at 1,346.15 feet — 30.78 feet lower than the 2023 flood level. The Ranjit Sagar dam, with a maximum capacity of 1,731.55 feet, currently stands at 1,664.72 feet — 5.49 feet below the 20-year average and 54 feet below the 2023 flood year level.
