The water needed for a proposed data centre in west Saint John wouldn’t be a significant drain on the city’s Spruce Lake industrial supply, according to the registration document filed as part of the environmental impact assessment process.

But the centre, which would have a natural-gas power-generation plant for some of its needs, would require a significant amount of power at 390 megawatts.

it would also produce enough greenhouse gases to make it one of the top emitters in the province, according to the environmental impact assessment, or EIA, documents registered last week.
