A standardized economic asset representing gallons/day, m³/day, pollutant-load treated of measurable water treatment infrastructure capability under defined operating conditions.
gallons/day, m³/day, pollutant-load treated define the canonical capacity units.
Treated volume, pollutant load, compliance, throughput, uptime, energy use, and permit performance establish the operational record.
Scarcity, utility, durability, demand, transferability, and revenue potential determine institutional relevance.
