Rate Calculations for 2021

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 2021, MWA customers in Macon/Bibb County will pay a base fee of $9.00 for water service, when 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 or 1 unit) is approximately 748 gallons. During 2021, charges for water consumption, or volumetric rates, have increased 5 cents when compared to last year, and are currently billed at $2.63 per CCF.

Those MWA customers receiving sewer services (a typical MWA water & sewer customer) with a 5/8-inch meter will pay a base fee of $9.00, plus consumption charges of $2.86 per CCF, which also includes a 5-cent increase over last year's rate. 

Also during 2021, residential customers without an irrigation meter (or just a standard meter) will pay sewer consumption charges on only 80% of the water metered on their account each month (rounded to the nearest CCF), but for no more than 30 CCF in sewer consumption. And customers with an irrigation meter will not pay sewer consumption charges on that irrigation meter, but they will pay sewer consumption charges based off of the reading on their (standard) residential meter, but for only 95% of that metered water use each month (rounded to the nearest CCF), with no cap on this consumption. 

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 during 2021, 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.
