Chemicals and Detergents
The following information is for Grey Water Interface Units which have washing machines, kitchen sinks, showers etc. connected to the vacuum
pipelines.
Chemical detergents, when used excessively, may result in foaming in discharges.
Chlorine content in detergents may also have a negative effect on the process in any connected sewage treatment plant, as chlorine will kill the
bacteria required in the process.

must ventilate the tank to counteract the oxygen deficient environment prior to
service being carried out. Under no circumstances should a person service the
tank without a second person standing by that can render aid if needed. If
extended periods of time are required for tank inspections/repairs, appropriate
respiratory equipment (PPE) should be utilized.

Disease Hazards: Effluent is a common mode of transmission for parasitic
organisms. Some of these may be pathogenic, meaning that they may
have the capability of causing serious communicable disease. Good
personal hygiene, use of disinfectant soap and avoidance of hand to
mouth transfer are necessary for all working in contact with the
equipment. Skin abrasions, punctures or wounds of any other nature
require immediate and proper medical attention.
