The distribution design and style ought to include things like the placement of sampling valves during the storage tank and at other destinations, for example within the return line in the recirculating drinking water program. Wherever feasible, the main sampling web sites for drinking water really should be the valves that supply h2o to the points of use. Direct connections to processes or auxiliary machines should be meant to stop reverse flow to the controlled drinking water process.
Bioburden is Usually outlined as the number of bacteria residing on a area that has not been sterilized.[1]
