These descriptions are useful planning benchmarks; actual charges can change with meter size, usage, sewer averaging, local taxes, drought stages, or account-specific fees.
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 and infrastructure notes
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.
