Based on the chart, residential sewer charges are reduced by 10% to account for non-sewer water usage like watering lawns. Homes with a dedicated meter for outdoor watering won't receive this discount on their primary meter usage. Each home or apartment is capped at a monthly sewer charge for up to 12,000 gallons of water use unless the minimum charge for the meter size is higher. In such cases, the charge matches the minimum for the meter size. There are no residential sewer credits for exceeding this cap. Industries with high BOD and solid concentrations pay extra charges and those deemed significant users must pay an annual $500 permit fee.
