the treatment plant https://dev.oieau.fr/uwwtd_it/agglomeration/it198901303/2014 in graphical network summary should have a colour (red or green but not black, check with rules but I guess red because secondary equipement is not provided, even if performance is at pass and required is secondary)
In this case, the required treatement is secondary and non require treatment in place (chlrorination) is fail, but it should be not disqualifying on compliance. Need check https://dev.oieau.fr/uwwtd_it/treatment-plant/it19sr00g0013de002/2014
