The Greater Hyderabad Municipal Corporation is going to carry out a GIS based survey and mapping of the city’s storm water drains, as a prelude to the proposed storm water master plan.
The geo-mapping of the storm water drains entails digitally mapping the entire storm water drainage network using geographic information system (GIS) technology on a base map created by drone survey.
It involves collecting accurate location, dimension, and connectivity data for all drain lines, culverts, catch pits, and linking them with geospatial coordinates, a statement from GHMC informed.
The main objective of the survey is to analyse model flow patterns, flood risk assessment and mitigation, simulate rainfall impact, enhance infrastructure planning and management, support smart city water management systems, strengthen emergency response during heavy rainfall, and enable real-time monitoring, it said.
Visual maps can be shared with communities to increase awareness of local drainage systems and encourage citizen reporting.
Recently, GHMC has been accorded permission by the government to go ahead with the storm water master plan for the Telangana Core Urban Region, with geo-referenced database of the storm water drainage system, and hydraulic and hydrologic modelling and analysis of the SWD network.
The master plan aims to provide a sustainable and efficient storm water drainage system mitigating urban flooding and ensuring the well being of the citizens, an order from the Metropolitan Area & Urban Development wing said, permitting the corporation to go ahead with the tendering process to select a consultant to carry out the master plan.
The endeavour will help analyse the drainage patterns and potential flood zones, and identify areas needing improved drainage systems. It will also help identify sources of storm water pollution and implement best management practices to reduce pollutants entering waterways and protect aquatic ecosystems. Prioritisation of infrastructural investments, and sustainable development have been cited as the other advantages of the master plan.
