The Greater Visakhapatnam Municipal Corporation (GVMC) is planning to introduce sensor-based underground drainage (UGD) monitoring system in the area-based development (ABD) part of the city. Ward numbers 17, 18, 19 and 20 come under the ABD area. The project will be taken up under the Vizag smart city project. The sewer lines under the manholes will be fitted with a sensor which will send various flow parameters to corresponding managing stations.
Currently, the existing manual UGD monitoring system takes up a lot of time. Officials cannot monitor the flow of sewage or the overflowing of manholes in real-time. The city’s civic body receives a lot of complaints about UGD leakages and overflowing manholes on a regular basis. Once the new system is introduced, officials will receive an alert when the UGD is about to overflow as the sensors will detect variations in the flow.
A GVMC official said that the civic body is currently preparing an estimated budget for the project. “A sensor-based UGD monitoring system will be introduced at key locations and the junctions of the ABD area. The system will help identify leakages in sewer pipelines and monitor the flow,” he added.
The official further said that the GVMC is also planning to introduce a robotic system for manhole and sewer line cleaning under a separate project. Nearly one year ago, the GVMC had launched works for an UGD project in the ABD area with and estimated budget of Rs 60 crore. The project was aimed at bridging the gaps in the UGD system in the ABD area.
The project will cover 8.8 km in the ABD area and lay a 7.1 km-long UGD network in Jalaripeta. According to GVMC officials, around 70 per cent households in the ABD area are connected to the UGD network. Officials say that the remaining 30 per cent will be connected through the current project. The connected sewage treatment plants will be retrofitted to ensure that the quality of discharges meet the norms laid down by the Central Pollution Control Board (CPCB).
