    The statement “Water is produced to WHO guidelines” is a tough claim to make. WHO drinking water guidelines are MANY and this treatment system has surely not been tested for meeting every drinking water guideline for every parameter (which would also depend on influent water quality). I think what they meant by this is that the treated water meets microbiological guidelines of <1 CFU/100 mL.

    I would suggest moving or modifying this comment/claim.
