Presented are results of investigations of multispark electric discharge in water excited along multielectrode metal-dielectric systems with gas supply into the inter-electrode gaps. The intensity distribution of discharge radiation in the region covering the biologically active soft UV (190 <=l <= 430 nm) has been determined and the absolute number of quanta in this wavelength interval has been measured. The potentiality of the slipping surface discharge in water for its disinfection is ana-lyzed. The energy expenditure for water cleansing is estimated to be as low as ~10^-4 kW·h/l.
