The flow factor is the percentage of metered water use returned to the sewer system as wastewater. Residential users may be eligible for a reduced flow factor if they are using large amounts of water to irrigate a lawn or garden and believe their annualized irrigation consumption is greater than 10%. Customers may request that their flow factor be reviewed by filing an appeal for a reduction of their sewer service charge. For more information contact (415) 551-4780 or visit Flow Factor.
