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 or quarterly depending on customer and service territory. Indiana American Water states residential customers are billed on regular meter readings, monthly or quarterly; West Lafayette tariff details must be confirmed from the account.
- Rate structure
- IURC-regulated meter-size and usage rates. Indiana American Water’s 2024 rate case created an affordability design in which a 5/8-inch residential customer using up to 1,500 gallons per month pays approximately $20 with no additional volumetric charge; usage above 1,500 gallons is billed under the applicable local tariff.
- Wastewater and sewer calculation
- Wastewater rates vary by community and may be based on water usage or local sewer flows. The reviewed Indiana American public pages do not expose the West Lafayette-specific wastewater formula.
- Meter reading
- Regular meter readings support monthly or quarterly billing depending on service territory. The reviewed public pages do not identify the local West Lafayette AMR/AMI technology.
