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
- Monthly. Richardson's online account displays billing and payment history and up to 13 months of consumption history; automatic bank drafts are taken on the due date or the preceding workday when the due date falls on a weekend or holiday.
- Rate structure
- Current rates effective November 1, 2025 and used in the FY2025-26 schedule are tiered conservation rates with a flat $8.00 monthly minimum per meter. Water volume is $7.77 per 1,000 gallons for 0-11,000 gallons, $8.41 for 11,001-20,000, $8.77 for 20,001-40,000, $10.20 for 40,001-60,000, and $10.66 above 60,000. Irrigation meters use the water schedule. Sewer has an $8.00 minimum and $5.53 per 1,000 gallons through 11,000, then $10.96 above 11,000. A flat $6.25 residential drainage fee and solid-waste charge are billed separately.
- Residential cost reference
- At the published Richardson residential schedule, 5,000 gallons is approximately $46.85 water ($8 + 5×$7.77), $35.65 sewer ($8 + 5×$5.53), and $6.25 drainage, or $88.75 for water/sewer/drainage. Adding regular residential refuse of $25.59 before tax produces about $114.34 before tax. At 7,000 gallons, the comparable total is $62.39 water + $46.71 sewer + $6.25 drainage + $25.59 refuse, about $140.94 before tax. Actual sewer volume is controlled by the winter-average ceiling and may be lower than current-month water use.
- Wastewater and sewer calculation
- Residential sewer is based on 98% of average winter water consumption when there is no separate irrigation meter. Richardson averages November-through-February billings across the last three years to establish a ceiling for sewer charges in the next year; when actual water consumption is lower than the ceiling, the lower amount is billed. Separate irrigation meters prevent outdoor irrigation from inflating the sewer basis. Sewer charges are $5.53 per 1,000 gallons through 11,000 gallons and $10.96 above 11,000, with an $8 minimum under the current schedule.
- Meter reading
- Richardson's water conservation materials identify Neptune T-10 meters with automated meter reading technology. The City replaced meters through a program completed around 2024 and provides online consumption history and graphs covering up to 13 months. The public materials do not specify the AMR transmission interval or whether customers receive hourly data; the customer-facing system is described as automated meter reading rather than AMI. The City also uses three-year November-February consumption history for residential winter-average sewer calculations.
- New-account deposit
- Richardson requires deposits on all water accounts. A residential house meter requires $75, and a separate irrigation meter requires an additional $75. The deposit is paid at application, held until service terminates, applied to the final bill, and earns interest credited to the customer account annually. Letters of credit are not accepted in lieu of the deposit. Commercial deposits vary by meter type and size, from $300 for 5/8- or 3/4-inch meters to $6,000 for a 10-inch meter under the current fee schedule.
- Activation or transfer fee
- Residential and commercial transfers are requested online, by phone at (972) 744-4120, or by email to customer.service@cor.gov. The current public transfer page does not publish a separate transfer fee. The adopted fee schedule lists a $15 regular-time and $25 overtime water service charge, while new-account deposits are $75 per residential house or irrigation meter. New residential applications require government identification and deposit payment; cash or check applicants must apply in person at the Temporary City Hall Annex.
