Median monthly bill at 4488 gallons: **$61**. 90th percentile: **$121**.

Each bill is computed from the fixed charge, the volumetric tiers and the unit of measure the system itself
filed in section 8a of its electronic Annual Report, evaluated at 4488 gallons. It is not the Board's
own figure: the Board publishes two undocumented charge fields, and reconstructing them from the filed
structure establishes what they are for systems billing monthly in hundred cubic feet and refutes it for
bi-monthly ones. These are reporting year 2025 filings and not necessarily the rate in force today.
