WFI point of use tank elimination

I work for downstream at a vaccine manufacturing plant. We use a WFI tank to fill with WFI from the WFI loop to connect to either the AKTA or the uniflux to clean the equipment. Recently, we have been getting a lot of bioburden hits and I was wondering if there was any alternative or suggestions to eliminate the use of a WFI point of use tank and to connect WFI loop directly to the equipment. Thank you in advance.
