First time in India, a study was aimed to establish a base-line data for electron beam radiation dose level needed to disinfect and also improve the water quality of sewage water for possible reuse in irrigation, industries as well as a few domestic purposes. Raw and secondary treated sewage water samples, which were rich with microorganisms from Navi Mumbai municipal sewage plant were irradiated with electron beam accelerator at doses of 0.45, 0.75, 1.5, 3.0, 4.5, 6.0, 7.5, 9.0 and 10.5 kGy.

Electron Beam (EB) dose of 1.5 kGy was sufficient for complete elimination of total coli forms whereas Cryptococcus laurentii, Aspergillus fumigatus and Absidia sp. were killed by10.0 kGy and no larvae of helminthes (Ascaris lumbricoides) were recovered at the dose ≥ 1.5 kGy. The experimental findings obtained highlighted the potential of this technology for disinfection of wastewater.
