Drinking water in Joliette
Joliette's water comes from the L'Assomption River, treated at the Pierre « Pit » Laforest plant through chlorination, filtration and ozonation — a facility recognized by Quebec's Drinking Water Excellence Program. The City's 2025 annual report shows no exceedance across 252 microbiological samples and 20 lead samples.
Two realities persist despite that compliance. First, lead: the City samples twenty pre-1975 buildings each year and replaces lead service lines during roadwork — meaning lead connections still exist in older sectors. Second, taste: the ozonation and chlorination required to disinfect surface water leave a signature many residents recognize in their coffee or tea.
Reverse osmosis comes after all of that, right under your sink — a final 0.0001-micron barrier that removes up to 99% of lead per NSF/ANSI 58 testing, along with chlorine and its by-products.
