UV Water Treatment Systems in Portland, ME

Chemical-Free Pathogen Protection for Portland Homes & Businesses

Ultraviolet disinfection systems destroy bacteria, viruses, and other pathogens by exposing water to UV light at 254 nanometers, the wavelength that disrupts microbial DNA and prevents reproduction. No chemicals enter the water, taste and odor are unchanged, and nothing is added to your water chemistry. At FONTUS Water Treatment, we install UV water treatment systems for homes and businesses throughout Portland, Maine, and the surrounding southern Maine area, starting with a free water test so the system we recommend matches what’s actually in your water.

Portland’s municipal supply draws from Sebago Lake, one of the cleanest source waters in the country. But water traveling through aging distribution infrastructure can pick up sediment, minerals, and microbial risk before it reaches your tap. For well-water users in the area, there’s no municipal treatment as a backstop at all, making UV disinfection a direct answer to bacterial contamination risk.

Ready to know what’s in your water? We offer free consultations and immediate-response water testing at no upfront cost. Call us at (207) 865-8165 to get started.

What UV Disinfection Targets

Standard sediment and carbon filters don’t address microbial threats. UV disinfection fills that gap, targeting E. coli, coliform bacteria, giardia, cryptosporidium, and viruses by rendering them unable to reproduce. Because it’s a physical process rather than a chemical one, nothing is added to your water, and no byproducts are created.

Portland Water District applies UV treatment at its Sebago Lake Water Treatment Facility, but distribution through aging pipes means a point-of-entry UV system adds a meaningful second line of defense at the home or business. One important condition: turbid water or high iron levels reduce UV light transmittance, and when those conditions exist, pre-filtration upstream of the UV unit is required for the system to perform at rated effectiveness.

VIQUA UV Systems: What We Stock & Install

We stock and install the VIQUA family of point-of-entry UV systems. The VIQUA HOME family covers residential and light commercial applications, with flow rates up to 18 GPM and configurations that add sensor technology, integral pre-filtration, or both.

Sensor technology configurations monitor UV lamp output continuously and alert you when performance drops, so you know the system is working at full strength. Integral pre-filtration configurations address sediment before water reaches the UV stage, protecting transmittance and extending lamp life. We select the right configuration for each property based on water test results, flow rate, and any co-occurring contaminants.

UV Treatment as Part of a Layered System

UV disinfection handles pathogens. It doesn’t address hardness, radon, iron, or manganese. In Portland, Maine, those contaminants frequently appear alongside bacterial risk, particularly in well-water properties where contamination can involve bacteria, minerals, and radon at the same time. A single-stage UV system won’t solve that combination.

We design every system around what a water test actually finds. Depending on results, we pair UV with pre-filtration, carbon filtration, absorption media systems, or Stenner Solution Feed systems to build a complete point-of-entry solution. We test for iron, manganese, hardness, total dissolved solids, pH, alkalinity, salinity, and copper, the contaminants that most often affect UV performance and overall water quality in this region.

Why Portland Homeowners Choose FONTUS Water Treatment

FONTUS Water Treatment was founded by Thomas Marcisso, a licensed Merchant Marine engineer who spent his career managing potable water systems on oil platforms and commercial vessels, including serving as Chief Engineer on the F/V Wizard, known from Deadliest Catch. Keeping water safe for a crew hundreds of miles from the nearest port is a different order of responsibility than quoting a product and scheduling a drop-in installation. That engineering background shapes how we approach every UV water treatment system we put in a home or business.

We’re a Water Quality Association member, and our service covers the full arc from initial testing through installation, client education, and ongoing maintenance. We don’t consider the job done at installation.

Our UV system service includes:

• Free water testing: We identify what’s in your water before recommending anything
• System selection: We match the VIQUA configuration to your flow rate, contaminant profile, and any upstream treatment needs
• Professional installation: Every system is installed by our team, not subcontracted out
• Client education: We can walk you through how the system works and what to watch for at handoff
• Ongoing maintenance: Scheduled inspections, UV lamp replacement, and prompt service keep the system performing reliably
