Advanced Residential Training Programme on Decentralised Wastewater Management and Local Reuse

School of Water and Waste (SWW) successfully completed an Advanced Training on Decentralized Wastewater Management and Local Reuse at AAETI from 21-23 December, 2021. This training was the second in series and held in collaboration with National Mission for Clean Ganga (NMCG).

The participants arrived at CSE head office a day before on 20th December and explored green features incl. 8 KLD DWWT system and RWH system implemented at CSE campus. After that we have departed from Delhi to AAETI for the further sessions.

The day 1 of the training started with AAETI campus tour where participants were taken to the various wastewater treatment systems (DWWTs, SBT, Improved Septic Tank) at AAETI to showcase the example of wastewater treatment and local reuse at small scale. Later on the the classroom training formally started with a room mapping session followed by a context setting session by Dr. Suresh Rohilla, Sr & Academic Director at CSE. The day was majorly focused on the contextualization of DWWTs in WSUDP Approach, institutional and regulatory frameworks, difference b/w centralise and decentralise approach, technological options, criteria for planning and designing a DWWT system. Apart from the sessions, participants performed a debatable exercise on how decentralise approach is better than centralise approach and what could be the advantages and disadvantages of the same. A self paced cultural night programme was organised by AAETI management.

On second day we have invited 3 guest speakers from reputed organisations like IARI, CDD Society and ESTPL (Subsidiary org. of NEERI). The first half of the day 2 of the training programme covered a session on economics and lifecycle resource recovery of DWWTs by Ms. Sandhya Haribal (Senior Project Manager, CDD Society) followed by a short session on operation and maintenance. Further, sessions on Jalopchar and Phytorid technology were taken by Dr. Ravinder Kaur (Principal Scientist, IARI) and Mr. Vivek Jangde (Dy. General Manager, ESTPL) respectively. The participants were exposed to CSE's EML/FSM laboratory to get idea of sample analysis and various apparatus/equipments used for the same. The second half od the day 2 covered a hands-on 'DIY' exercise on planning and designing a DWWT system for institutional and residential township. As an outcome of the final exercise, participants presented their planning and detailed calculation. We have also given prizes to the best group of the final exercise as well as few prizes in different categories to encourage the participants. Apart from all these, early morning participants were taken to a short Trek on aravali hills.

On day 3 early morning we have departed from AAETI to Delhi for the field visit at Ayanagar to see the small scale community level sanitation system including a 100 KLD Reedbed system. After the field visit participants were taken to the CSE office for cerificate distribution and a short feedback interaction with the training director.

We have received 360 degree good response from participants in terms of content, methodology, organization of the training, time management, field visit and co-curricular activities.
