Surface Water Treatment for Noncommunity Public Water Systems
A noncommunity public water system provides water to the public in places other than their homes—where people work, gather and play. There are around 6,000 noncommunity systems in Minnesota. Of those, around 60 use surface water sources such as lakes and rivers. Public water systems using surface water sources must provide filtration and disinfection treatment and regularly monitor their treated water quality.
