Partner Organization: Centre for Technology Alternatives for Rural Areas (CTARA), IIT Bombay

Project Leader : Prof. Bakul  Rao, CTARA, IIT Bombay


  • Design a model WATSAN (water supply, sanitation/drainage, stormwater management and solid waste management) system for a town of 20,000 population based on available data and onground conditions. 
  • Convert this experience/process into an a state of the art IT-enabled design tool for wider application to other locations.

With WIN Support, CTARA selected Vadgaon Maval and Faizpur towns in Maharashtra for the project. The work encompassed:

  • Comprehensive survey of water supply using pipeline mapping, measurement of flow and pressure, and water quality, civil survey with elevations, using remote sensing/satellite data and mapping with open source GIS system. 
  • Social survey of 100% households including water connections, toilet positions with soak pits and septic tanks, willingness of household to join the sanitation programme and perception of residents towards current water supply. 
  • Using above inputs, the team then designed (i) a comprehensive WATSAN system including an appropriate water supply network,  sewerage network, sanitation scheme, stormwater drainage network and solid waste management plan, using tools like hydraulic modeling, GIS etc., (ii) state of the art process and design tool set for wider application to other towns, (iii) training and other support modules to guide implementing agencies.
