Billing and account research from public material
Provider-specific research notes are displayed separately from fields that contain only an unavailable-information marker. Read qualifiers in each note and verify current account terms with the provider.
- Billing frequency
- Bi-monthly. Water usage and sanitation are billed for two-month periods: November-December billed in January, January-February in March, March-April in May, May-June in July, July-August in September, and September-October in November; payment is due early the following month.
- Rate structure
- Uniform volumetric rate above a meter-size minimum. Effective January 1, 2026 with no increase, a 5/8- or 3/4-inch meter has a $17.21 minimum every two months including the first 500 cubic feet, then $4.82 per 100 cubic feet. Affordable-rate customers who qualify through CEDA or a City benefits card receive reduced usage rates.
- Residential cost reference
- For a 3/4-inch account using 6,000 gallons each month, the two-month bill covers about 1,604 cubic feet: water is approximately $17.21 plus 1,104 cubic feet over the included 500 at $4.82/100, or $70.42; sewer is $13.30 plus the same excess at $2.66/100, or $42.66. Combined water and sewer are about $113.08 per two-month bill, or approximately $56.54/month before sanitation charges.
- Wastewater and sewer calculation
- Sewer is billed every two months using the same metered water consumption unit. The minimum sewer charge is $13.30 and includes the first 500 cubic feet; additional consumption is $2.66 per 100 cubic feet. Tax-exempt properties pay $4.53 per 100 cubic feet above 10,000 cubic feet in a billing cycle. The City also publishes affordable sewer usage at $1.94 per 100 cubic feet for qualifying customers.
- Meter reading
- Evanston operates an AMI system for approximately 14,500 accounts. A Meter Information Unit attached to each meter reads hourly and stores a full day's readings; it broadcasts once daily to six Data Collector Units, which send data to the water-treatment-plant network and billing system. The system generates hourly usage data, leak alerts, and bi-monthly bills, and customers can monitor usage through WaterSmart.
