Medications – Normal use of over the
counter medications will not affect the performance
of onsite systems; however, do not flush expired
medicines/antibiotics into an onsite treatment system.
Some prescription medications are known to cause
biological disruption. Diseases or conditions which
can affect septic system function include bulimia,
severe infections (including AIDS), chronic diarrhea,
intestinal/colon by-pass, or other gastrointestinal
conditions and cancer. Oral or intravenous chemotherapy
is known to severely disruption to the treatment
process and require more frequent pump-out intervals
or the use of biologically based additives.
