The two research studies have to be carried out under the CCBP. These are as under:
- Case studies on urban rainwater harvesting from different agro-climatic regions
This report has reviewed 12 case studies out of total over 80 RWH projects identified from across India. After detailed analysis of successfully implemented RWH projects from different agroclimatic settings two case studies have been selected – one each from low (scanty) and very high rainfall area.
First, is the case study of a residential complex in Umaid Heritage – Birkha Bawari located in Jodhpur, Rajasthan known for low and scanty rainfall. Second, case study is of Goa University campus located in very high rainfall region. In other words, people have implemented RWH, with the excesses of water, and its scarcity.
The sustainable water management requires understanding the value of rain, and to make optimum use of rainwater at the place where it falls.
- Case Studies on Decentralised Wastewater Treatment (DWWT) and Reuse
This report has reviewed 11 case studies out of total 19 projects of DWWT identified from across India. After detailed analysis three case studies of implementation on different scale have been selected – one each at community, institutional and individual household building. All three case studies use natural technologies with minimal or no electricity requirement for treating wastewater and also locally reuse treated water. First, is the case study of Naval Civilian Housing Colony located in Kanjurmarg, Mumbai known for neighbourhood/community scale wastewater treatment using – Soil Biotechnology (SBT). Second, case study is of the National Environmental Engineering Research Institute (NEERI), Worli, Mumbai treating wastewater using – Phytorid Technology. Third, case study is of individual household building DWWT system located in Sangli City, Maharashtra. The wastewater is treated using – Fixed Film BiofilterTechnology (FFBT).
The sustainable water management requires understanding the potential of local reuse.
