We are living in water-stressed times. Approximately four billion people experience severe water scarcity at least one month per year. It is estimated that by 2030, 700 million people worldwide could be displaced due to intense water scarcity. The growing demand for water comes at a time when the potential for augmenting supply is limited, water tables are falling and water quality issues have increasingly come to the forefront. The current water paradigm, primary focuses on the supply side management and providing hardware solutions is unsustainable and non-feasible. This further aggravates the problem of inadequate municipal supply, ground water depletion and water pollution. A proposed alternative to the growing water crisis that is increasingly being considered is use of wastewater as a resource. At present, 80% of wastewater worldwide is released untreated in the environment and in developing countries such as in India only 22% of sewage generated is treated. Research findings have explored the huge potential of wastewater and reusing and recycling of treated wastewater to augment freshwater sources and mitigate water stress. Moreover, policy frameworks all over the world also emphasize on the reuse and recycling of treated wastewater for local purpose. This calls for a paradigm shift from the current centralized approach to one which is sustainable in nature and emphasizes on the reuse and recycle of treated wastewater. One such sustainable approach is decentralized wastewater treatment as it addresses the problem of water pollution and scarcity. The approach is based on the important principle – devolving level of the application so that wastewater can be treated at affordable costs, cutting the cost of pumping long distances and promoting local reuse of treated wastewater. It provides an added advantage to meet the huge demand of non-potable water which does not require tertiary level of treatment, thus reducing the stress on water sources.

To build awareness about issues and potential of decentralized wastewater treatment including successfully implemented case studies of local reuse of treated wastewater.   

Learning Objective:

  • To understand the existing problems in wastewater management.
  • Understanding of the definition, concept and approach of decentralized wastewater treatment vis a vis centralized wastewater treatment and its intervention in urban areas.
  • Acquaintance to web based portal MOUNT – case studies showing different technologies and cost effectiveness. 
  • Understanding about the enabling frameworks and regulations applicable to decentralized wastewater treatment including reuse. 

Understanding about the enabling frameworks and regulations applicable to decentralized wastewater treatment including reuse.  

Programme Design
The programme comprises of self-study, technological learning tools such as presentations, videos featuring case studies from various countries and other audio material. It will facilitate interaction amongst participants through online forums and discussions. It will be interactive course with periodic assessment through group discussions, exercises and quizzes. Participants will also get a chance to interact and learn from experts at CSE and abroad through online interactions and a webinar.

Participants are expected to will complete the course in a period of about four weeks with a workload of 24 hours. Participant is expected to spend about 6 hours per week on reading, discussion, interaction and assignments. At the end of the week and module, participants are expected to submit an assignment based on their learning. These assignments may have multiple choice questions, short answer type questions, quiz or essay type of question. Assessment will be done on the following criteria –

  1. Comprehensiveness of observations and problems identified
  2. Extent of critical engagement with course learning
  3. Depth and nuance in suggested interventions
  4. Ability to critique self-developed strategy 

At the end of the course, the participants would also get bonus points for being attentive, creative and responsive during the training programme. 

Target Audience:

  • Working professionals and decision makers from government and non-government institutions
  • PMU assisting Govt. in mainstreaming water-wastewater measures
  • Urban Planners, Architects, Engineers and Consultants

I wanted to thank the team of CSE for organizing such an awesome training. We are not only taking back with us the learnings from the training but also wonderful friends for life which have made our 10 days long training very smooth and memorable. The experience gained because of the friendly and helpful trainers with expertise in their sector was a rarity. We will be now in close contact with the team for seeking help and informing about implementation of the learnings. Thank you once again to all for the active participation!’
