Including filter system and high-performance HPC Bacteria filter.
HPC bacteria are a wide-ranging group of naturally occurring microbes that can live in water and inside household plumbing. You may also see this described as heterotrophic plate count, which refers to a lab method used to estimate overall bacterial presence rather than a single organism. Elevated HPC results often point to conditions that let bacteria grow, and Lake Lorraine homeowners sometimes notice signs like musty smells, slippery buildup, or faster biofilm formation on faucets and showerheads.
Levels of heterotrophic plate count can climb when water sits in pipes, when sediment or organic material is present, or when plumbing surfaces support biofilm growth. These general bacterial changes can accompany shifts in taste or odor, even though many heterotrophic bacteria are not classified as disease-causing. For Lake Lorraine residences, taking a whole-house view helps treat the water entering your home and reduces the conditions that allow regrowth further downstream in your plumbing.
The most effective single, whole-house filter-style option for reducing HPC bacteria is a ultraviolet (UV) disinfection system. UV systems inactivate microorganisms as water flows through a stainless steel chamber and is exposed to a UV lamp, treating water in real time without adding chemicals or altering taste. Installed where water enters a Lake Lorraine home, a properly sized UV unit protects every tap, shower and appliance from heterotrophic plate count concerns.
For UV to perform reliably it needs clear water so light can reach microbes; heavy sediment, iron, or cloudiness can shield organisms from the lamp. That’s why many whole-house setups pair UV with prefiltration, while the UV stage remains the primary technology targeting HPC bacteria. Correct sizing for your household flow and regular lamp and sleeve maintenance keep the system working well—Mr. Pure Water can help Lake Lorraine homeowners select and install the right whole-house UV system for consistent heterotrophic plate count control.
