Automating Floodgate Operations and Monitoring

Water Resource Management

1. Automation of Floodgate Operations:

   • The Water Resources Department (WRD) is implementing automation of floodgates in city reservoirs through a SCADA (Supervisory Control and Data Acquisition) based decision support system.
   • Objective: To enable real-time monitoring of storage and inflow to mitigate flooding, especially during the monsoon season.

2. Reservoirs Involved:

   • Key reservoirs: Poondi, Red Hills, Chembarambakkam.
   • Current practice includes manual operations for discharging water to manage flood risks.

3. Operational Enhancements:

   • The automated system will analyze rainfall runoff, assess reservoir fill times, and share real-time data with government agencies, enhancing response times to flood threats.
   • Installation of automated sensors (water level recorders, flow sensors, gate sensors, and bullet cameras) to collect data for decision-making.

4. Infrastructure Preparedness:

   • Most infrastructure for remote monitoring is ready; the system set to be operational during the next monsoon rainspells.
   • Integration of a centralized control room at the Cooum River with onsite controls at the three reservoirs.

5. Economic Investment:

   • Total investment for the project: ₹32 crore.
   • Goals include optimizing water resource management through balanced reservoir levels and city water supply, especially in summer.

6. Environmental Monitoring:

   • Continuous monitoring of river basins, including Kosasthalaiyar, for reservoir levels, inflow velocity, and flood discharge control.
   • The project aims to mitigate flood risks in low-lying areas by managing water discharge efficiently.

7. Data Management Features:

   • The integrated command center will provide graphical displays of inflow, outflow levels, sluice gate positions, and tidal effects in waterways.

By automating processes and introducing a sophisticated monitoring system, the WRD aims to enhance flood management, water conservation, and overall resource allocation within the urban water system framework.
