Code
CONTAMINANT removed by cleaning shall be disposed of in a sanitary manner or as required by law.
Annex
Currently, there are no standardized procedures for removing CONTAMINANTS, particularly those found in biofilms/slime layers, in piping, or AQUATIC FEATURES that spray or dump water. All water features should be well drained and disinfected per manufacturer’s instructions. Development of appropriate guidelines deserves further investigation and data gathering.
