## ANSWER

## MINISTER OF STATE (INDEPENDENT CHARGE) SCIENCE AND TECHNOLOGY AND EARTH SCIENCES (DR. JITENDRA SINGH)

- (a)&(b)   CSIR-Central  Mechanical  Engineering  Research  Institute  (CSIRCMERI), Durgapur, a constituent laboratory of Council of Scientific & Industrial Research  (CSIR) has developed  a vehicle  mounted mechanized  sewer  cleaning  machine.  The  technology  is  vehicle mounted mechanized drain cleaning machine which is fully indigenously developed, integral and self-powered in nature, developed with a noble intention to eradicate the manual scavenging process and also to provide one-point solution for all sewer related problems  like,  sewer  chocking,  overflowing  manholes,  damaged sewer  pipelines  etc.  The  advantages  of  the  developed  vehicle mounted mechanized sewer cleaning machine are as under:
-  Utilization of Drain Slurry Water for Chockage cleaning. (Minimising the usage of the freshwater)
-  High-Pressure Jetting System & Inbuilt Disinfectant System
- 
- Equipped with a Closed-loop operator feedback system
- 
- Post-cleaning inspection camera system (self-propelled type)
-  Indigenous and Cost-effective

Further, CSIR-CMERI has recently developed a compact vehicle and integrated  mechanized  septic  tank  cleaning  machine  for  faecal sludge  management.  By  automating  the  cleaning  and  treatment process,  this  technology  significantly  reduces  the  risk  of  human exposure  to  sludge,  improves  cleaning  efficiency,  and  minimizes environmental contamination. Additionally, the compact design of the  system  makes  it  suitable  for  navigate  in  narrow  lanes.  The advantages  of  the  developed  mechanized  septic  tank  cleaning machine are as under:

-  Mechanized cleaning of onsite sanitation system (septic tank)
-  Onsite  dewatering  of  septic  tank  faecal  sludge  and  onsite
- wastewater treatment
-  No electric power requirement to operate the machine
-  Compact  design  of  septic  tank  cleaning  machine  suitable  to navigate in narrow lanes (>8 feet road).
-  The  septic  tank  cleaning  machine  has  been  designed  and manufactured  with  around  80%  indigenous  components  and technologies.
-  Suitable for household septic tank used by up to 10 people
- 
- Range of septic tank users: 5-10 people
-  Household  septic  tank  cleaning:  Designed  as  a  self-powered compact  vehicle  integrated  septic  tank  cleaning  machine  to clean household septic tank unit
- (c)&(d) Yes,  Sir.  The  technology  of  vehicle  mounted  mechanized  drain cleaning machine has been transferred to the following industries
-  M/s Kam Avida Enviro Engineers Pvt.Ltd., Hinjewadi, Tal: Mulshi, Dist.Pune, Maharashtra
- 
- M/s Maniar & Co., Ahmedabad, Gujarat

Further,  the  Technology  of  Mechanized  Septic  Tank  Cleaning

Machine has been transferred to the following industries:

- 
- M/s. Subham Corporation, Ahmedabad, Gujrat
- 
- M/s. Amvica Industries, Ahmedabad, Gujrat
