Delhi Government commissioned Indian Institute of Technology, Delhi to draw up a Master Plan for the city's drainage system but it has not provided them all the information. The project, lead by Prof A K Gosain of the Department of Civil Engineering at IIT-Delhi, involves photographing drains and waterlogged areas.
Gohain, along with six faculty members, will be looking at the volume of water that has to be drained and if the drains are of adequate size and design. "The locals will know best which segments of the system are not functional — where there is stagnant water, etc," says Gohain.
Experts working on the project will need complete data that can be used for "simulation" to mathematically prove what can happen. However, the information provided by the Delhi Government doesn't include all the details. For instance, there isn't a full count of the bellmouths for storm drains or manholes for the sewage system, nor is there data on the grades, slopes and actual layout of the drains. The team will need the assistance of about 4,000 volunteers to gather, maintain and analyze the data. About 70 visitors, most of them students, had registered at IIT-D's I2Tech Open House held in April. But Gosain says that his team will need about 4,000 volunteers to cover each locality of about 4 sq km.
The photos of choked drains and similar problem spots will have to be sent to the team or uploaded directly for plotting on a map. "We have a detailed map of Delhi with geo-references. Every point on that map has coordinates. Information will be communicated to and stored in the server at GIS laboratory of IIT-D's civil engineering department. If photographs are taken with a 3G smartphone, the phone will automatically record the coordinates at which the photograph was taken. But the team is also experimenting with other ways of mapping data.
