How these are counted
“Modelled” is NI Water's hydraulic-model prediction of spills per year. “Measured” is from NI Water's event duration monitors, counted with the industry 12/24 method (discharges within the same 12- or 24-hour block count as one spill); the bathing-season figure (1 Jun–15 Sep) is our count from NI Water's published discharge log. An overflow with no monitor isn't known to be dry. Classification is NI Water's own.
