What is strong waste?
Strong waste is a term applied to the relative strength of a commercial or industrial liquid waste that is discharged into the County’s sewer system. If the discharge exceeds 250 mg/l BOD or 250 mg/l TSS it is considered to be a strong waste. By definition, if any commercial or industrial customer exceeds these threshold values the customer is defined as a “strong waste customer.” Customers that discharge strong waste to the County sewer system will have a sewer surcharge added to their sewer bill based on these criteria.
