Heavy Water Board, a constituent unit of the Department of Atomic Energy has set up a Sewage Treatment Plant (STP) at Sneh Rashmi Botanical Garden, Bhesan Road, Ugat, Surat to demonstrate the “hybrid granular Sequencing Batch Reactor (hgSBR)” technology developed by Bhabha Atomic Research Centre (BARC) (https://www.barc.gov.in/technologies/sbr/index.html). The STP unit with daily sewage treatment capacity of 150 KL has been operating since 01.08.2023 meeting the norms of Gujarat Pollution Control Board and successfully demonstrating the technology.

On August 22, 2024, Dr. A. K. Mohanty, Chairman, Atomic Energy Commission & Secretary, Department of Atomic Energy, Government of India along with Shri Vivek Bhasin, Director, Bhabha Atomic Research Centre, Shri S. Satyakumar, Chairman and Chief Executive, Heavy Water Board and Shri K. V. Tale, Associate Director (O), HWB handed over the STP to Surat Municipal Corporation (SMC). Smt. Shalini Agarwal, Municipal Commissioner, SMC along with Senior Officials of SMC took over the plant from SMC side. The ceremony was conducted at KRIBHCO Auditorium followed by the site visit at Sneh Rashmi Botanical Garden, Ugat. Senior officials from DAE, BARC, HWB, SMC and KRIBHCO were present during the function.
On the occasion, Dr. Mohanty said that R&D units of DAE are developing various technologies for societal benefit under AtmaNirbhar Bharat Abhiyan. Under this scheme, BARC has developed this hgSBR technology which is a compact biological treatment method for effective removal of contaminants from domestic and industrial wastewaters. DAE envisages  to expand the application of this technology at larger scale. 
Shri Vivek Bhasin, Director, BARC mentioned that BARC is working on various nuclear reactor technologies, fuel reprocessing and waste management, isotope applications, radiation technologies and their application to health, agriculture and environment. The hgSBR is one of such technologies which will be beneficial for larger public. BARC has transferred this technology to more than 20 private parties, who are building STPs using this technology. 
A brief presentation was made by Dr. T.V. Krishna Mohan, Head, WSCD, BARC on technological aspect of the hgSBR and emphasized on advantage s of this technology over conventional one. He also presented the operational performance data of the STP for one year. This technology enables building compact effluent and sewage treatment plants with smaller land footprint and lower costs as compared to other methods. The value of the resources recovered from wastewater treatment plants i.e. treated wastewater and fertilizer-supplement, can partly recover the operational cost.
Shri S. Satyakumar, Chairman and Chief Executive, HWB delivered the key  note address. He stated that HWB, an industrial unit of DAE, supports Indian Nuclear Power Programme through production of heavy water and specialty materials. HWB is also actively involved in Nation building activities & projects associated for societal benefit such as production of Oxygen-18 water, Deuterated compounds, Deuterium Depleted Water (DDW) for medical use, Hydrogen, Cobalt from industrial scrap, Gallium, and many more. This hgSBR STP project was taken up to demonstrate indigenously developed technology for public use. He thanked SMC for cooperation. HWB looks forward  for deployment of  this technology at larger scale. 
This technology  will attract more agencies such as municipal corporations and private players to adopt the same at larger scale. This can also be used for retrofitting the existing plants for enhancing treatment capacity with better treatment performance. It can also be used for designing packaged STPs in residential societies, hospitals, school and colleges.
