How we calculated this

Read by an AI agent (a large language model) from the utility's official rate schedule, then audited by a second model against the same schedule.

Extracted by: Audit · Claude Opus 5.5 · 10/19/2026

Source:

Quarterly service charge for a 5/8" meter, $25.22 ÷ 3 = $8.41/mo
Usage: 18,000 gal per quarter, the first 10,000 at $5.04/kgal and the next 8,000 at $5.24/kgal = $92.32 ÷ 3 = $30.77/mo
Public fire protection charge, $6.60 per quarter ÷ 3 = $2.20/mo
Total: $41.38/mo
