Wastewater and sewer calculation

Katy’s sewer code bases sanitary-sewer charges on building use and water consumption under the City’s rate schedule. The published rate sheet lists single-family sewer rates of $5.98 for 0–3,000 gallons, $1.23 per thousand for 3,001–8,000, $1.17 for 8,001–12,000, $1.11 for 12,001–15,000, and $1.04 above 15,000. The public schedule does not describe a winter-average calculation; sewer-only customers may be billed from estimated consumption plus the applicable administrative charge.

Meter and infrastructure notes

Katy reads all meters electronically on the 15th of each month. The public materials do not identify the manufacturer or guarantee hourly AMI data, but the City’s online account provides consumption history and payment history. Monthly readings are used to calculate the tiered water and sewer charges; customers can request emailed bills and monitor consumption through the online account.
