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. South Pasadena’s current rate notification publishes bi-monthly tier allocations and fixed charges; the bill period and due date on the MuniBilling invoice control.
- Rate structure
- Bi-monthly increasing-block water rate with fixed meter service charge and efficiency fee. The City’s published 2023 schedule lists Tier 1 at $3.75, Tier 2 at $4.72, Tier 3 at $5.53, and a $0.14 efficiency fee, with tier allocations based on meter size. Current 2026 charges should be confirmed in the adopted rate schedule.
- Residential cost reference
- Using the City’s published schedule as a directional estimate, a 3/4-inch account using 5,000–7,000 gallons per month is approximately $120–$150/month water-only equivalent because the fixed bi-monthly meter service charge is $94.28 and the first 15 HCF per bi-monthly period are in Tier 1; actual 2026 rates, usage allocation, and billing period control.
- Wastewater and sewer calculation
- South Pasadena publishes a sewer charge separately from water: the 2023 schedule lists a $30.45 single-family fixed charge per EDU per bi-monthly bill and a $2.01/HCF commercial flow charge. The reviewed materials do not state a residential winter-average formula; the fixed residential EDU charge is the documented ordinary residential structure.
- Meter reading
- The reviewed South Pasadena pages do not identify an AMI vendor or exact route schedule. The system is metered and billed bi-monthly; customers should use MuniBilling’s account records and contact the Water Division for individual meter or reading questions.
- Activation or transfer fee
- The City’s fee schedule includes a Water New/Change Account charge; the retrieved 2024 schedule text identifies $118 in the referenced table. Confirm the current 2026 charge with City Finance at (626) 403-7250 before activation or transfer.
