Loch Lomond facility supplies east/north/south and part of west; South Bay wells supply about one-third of west-side demand, with the balance from Loch Lomond. Spruce Lake / Ludgate Lake reservoirs now supply industrial raw water (and remain a long-term backup), not residential potable water.

Saint John Water serves roughly 17,000 customer accounts. Loch Lomond facility supplies east/north/south and part of west; South Bay wells supply about one-third of west-side demand, with the balance from Loch Lomond. Spruce Lake / Ludgate Lake reservoirs now supply industrial raw water (and remain a long-term backup), not residential potable water.
Safe Clean Drinking Water Project (~$225M) replaced frequent boil-water history by splitting potable supply between Loch Lomond surface water and South Bay groundwater, while dedicating Spruce Lake to industry.
