Underground utilities out of GIS-based digital map March 22, 2010Posted by Bahadir Sahin in English, Haber (News).

The city’s century-old water network will not be mapped, with the Brihanmumbai Municipal Corporation (BMC) deciding to leave out underground utilities as it prepares to undertake a project for a GIS-based digital map of the city’s properties.
The absence of a complex underground utility network had often resulted in workers damaging pipelines while digging roads. The city has had 51 pipe ruptures in the last four years, six of them in the last two weeks, resulting in the wastage of millions of litres of water.
The BMC is in the process of preparing a GIS-based digital map for future development projects, marking each surface civic structure from a manhole to a building. But a high price quoted for the mapping of the city’s 40 lakh properties has resulted in the BMC dropping underground mapping.
“If we are to map over and underground amenities as earlier planned, the price will be not less than Rs 240 crore and we have a budget of only Rs 32 crore,” said a civic official. “We will conduct the underground survey of pipelines in later stages.”
Deputy municipal commissioner (water supply) Dineshchandra Gondaliya said although there is an old water pipeline map, it excludes newly developed areas. “Having the utilities mapped is important not just for the BMC but also for other agencies when we give permission for digging roads,” he said.
An area-wise map of underground utilities would have helped the BMC undertake excavation for development projects or carry out repair work without fear of damaging the mains.
