The Bhandara Municipal Council (BMC) planned a project under Maharashtra Suvarna Jayanti Nagrotthan Mahabhiyan to bring significant improvement in service delivery and improve public health. The project aims at collection of the domestic sewage by laying lateral and trunk mains in the town; transportation of the collected sewage to the sewerage pump house and finally to the sewage treatment plant in the town; and treatment to the sewage at sewage treatment plant (STP).

For this, ADCC Infocad, a GIS and engineering solutions provider was roped in for modeling the sewer network using international-standard sewer modeling software. This software was to be used for preparation of land-base as well as database linking and analysis of the survey data, population density and preparation of the maps in the presentation format.

The proposed scheme mandated that the existing open drainages will be used for the storm water. But, since the municipal council did not possess any data of these drains, it was necessary to map them. However, the project duration of six months included the monsoon season. Traditional mapping, using paper maps, would delay the initiation of the project. Another challenge was the topography of the town.

Mobile mapping to the rescue
To overcome these challenges, ADCC used a mobile mapping application called ESRI Collector app for this. This app can be used on smartphone and tablet to collect information in the field, whether connected or disconnected. Apart from data, it can also capture position, pictures and spatial data. App features enable direct integration of the data by syncing with central facility at Nagpur through the GPRS network which considerably reduced the time and efforts required for the integration.

For the preparation of the estimates for excavation of conduits and manholes road surface is required. The municipality also lacked with the updated data of road type. To overcome this problem, ADCC added one more feature in the app wherein a user could attach the road surface type to the road centerline, enabling easy calculation.

Today, over 70% of the project is already complete. The mapping activity along with the integration part has also been successfully carried out. The sewer modeling part of the project has also been done. The process of estimate and DPR preparation is underway, which will be followed by the approval from government.
