Rate Calculations

The typical residential water bill is based on service from a 5/8" customer meter. Rates vary slightly according to meter size, with base fees increasing with the size of the respective customer meter.

In 2012, MWA customers in Macon/Bibb County continue to pay a base fee of $7.50 for water service, using a typical 5/8-inch residential meter. Consumption, or the volume of water that flows through that meter each month, is measured in 100 cubic feet; whereas, 100 cubic feet of water (1 CCF) is approximately 748 gallons. Charges for consumption are billed at $1.72 per CCF for the first three (3) CCF; and each additional CCF over that initial (3) CCF amount is billed at $1.82.

MWA sewer customers pay a base fee of $6.25, plus consumption charges of $1.86 per CCF for the first 3 CCF, and then $1.96 per CCF thereafter, up to 30 CCF, which is the new cap placed on sewer consumption charges by the MWA Board to benefit residential sewer customers.  In addition, residential customers without an irrigation meter will pay only 80% of the water metered on their account each month, while  customers with an irrigation meter will pay consumption charges on only 95% of their water volume each month.

The typical family of four uses approximately 12,000 gallons, or 16 CCF, of water per month.  The following document shows how the monthly water and sewer bill is calculated for this residential customer account, including how charges are reduced for sewer service for those customers with and without an irrigation meter.  Check out the following link for the specifics about how a hypothetical customer's water and sewer bill is calculated.

Commercial and industrial customers are billed according to their actual consumption or use of water and/or sewer services, which will be applied to each bill unless they indicate they have a flow meter.
