Use Case #1: Water Quality Monitoring and Management for the Guwahati Water Distribution Network
Current Situation in Guwahati Metropolitan area:
- Water supply facilities cater to less than 30% of the population, for about 1-2 hours per day,
- Most of the plants and pipelines have outlived their designed life period,
- Individual homes construct local storage tanks to achieve 24/7 water supply, but water may be stored there for a month making it undrinkable,
- 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 hr per day to 12 hr per day for Guwahati residents,
- 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 for intermittent water supply conditions 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.
