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.
Nearest wastewater treatment works: Newcastle WwTW (1.3 mi → Dundrum Bay Outer) · Maghera Down WwTW (1.8 mi → Carrigs River).
