Method
Residual = external inflows − discharge − consumption − increase in stored water. Internal reuse is reported separately and is not added as a new external source.
Scope and limitations
Use matching boundaries and periods. Zero residual does not prove measurement accuracy. Consumption estimates must not double count reuse or discharge.
