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. The district’s official bill calculator and sample bill describe a 30-day billing period and monthly water commodity and service charges.
- Rate structure
- Increasing block water-usage tiers billed in hundred cubic feet, plus a meter-size service charge. The official sample bill shows 9.33 HCF in Tier 1 at $4.96 per HCF, 5.67 HCF in Tier 2 at $5.93 per HCF, and a 3/4-inch service charge of $44.95; the operative rate schedule can change by adopted county resolution.
- Wastewater and sewer calculation
- The official Moorpark sample bill includes a separate $30.50 sewer charge for the monthly statement, while water usage is metered in HCF. The reviewed public material does not expose a complete current sewer formula, winter average, or usage-tier calculation.
- Meter reading
- The sample bill provides prior and current meter reads and a 28-day usage period, but the reviewed official pages do not identify whether the local residential meters use AMR, AMI, or manual reading.
