In some cases, lab waste may be excluded from hazardous waste regulations when properly discharged to a sewer system and mixed with domestic sewage that will be treated in a publically owned treatment works (POWT).
In other cases pouring lab waste down the drain is considered impermissible dilution. Also, some wastes are prohibited from being introduced into a POTW.
