Current situation in Guwahati Metropolitan area:

  • Water supply facilities cater to less than 30% of the population, for only about 1-2 hours per day,
  • Most of the plants and pipelines have outlived their designed life period and are prone to leakages leading to the infiltration of contamination,
  • Consumption of groundwater with heavy metal can lead to life-threatening diseases.

Key aims for improving water supply in the Guwahati Metropolitan area:

  • To increase water supply from 2 hours per day to 12 hour per day for Guwahati residents in the South Central Area,
  • To enable tap water to be consumed without further local treatment,
  • To reduce operational cost by 10 % and Non-Revenue Water (NRW) by 10 %,
  • To optimise chemical dosage by 10% with the help of optimal control algorithms and real-time sensing of residual chlorination levels.

How LOTUS will improve water supply in the Guwahati Metropolitan area:

  • The Guwahati Water Board is planning a major upgrade of the network with the long-term goal to provide 24/7 water supply,
  • The placements of LOTUS sensors will be optimised to allow the aims to be achieved at minimal cost,
  • The distribution network design and design standardization for intermittent water supply networks will be addressed.

Outcomes of Use Case 1:

  • Provision of a safe drinking water supply, without local treatment, free from water-based diseases.
