An ultraviolet (UV) unit consists of three main components: a treatment chamber, the UV lamp, and the power/control box.  The treatment chamber is a stainless steel, pressurized vessel containing an inner sleeve made up of high purity quartz.  The UV lamp is located within the water-tight quartz sleeve, where it remains separated from the water.  Water passes through the enclosed chamber, where it is exposed to the UV energy.  This dose of UV energy is lethal to bacteria, viruses, and molds, as the genetic structure (or DNA) is destroyed when exposed to the UV wavelengths emitted from the lamp.  Once the DNA is destroyed, the organisms can no longer multiply, which renders them harmless to humans and the environment.  The germicidal effectiveness peaks at around 265 nm (nanometers), one of the most effective wavelengths for eliminating bacteria and other microbes.  

The Viqua UVMax Integrated Home System includes a high flow 10″ “big blue” filter to remove sediment and a 20″ “big blue” carbon filter to remove taste and odor.  The cartridges need to be replaced about every six months and the UV lamp needs to be replaced annually.

An Ultra-Violet (UV) Light Unit is a whole-house system used to eliminate 99.99% of bacteria and viruses, including chlorine resistant cysts such as Cryptosporidium and Giardia from the water.

UV technology is used to destroy harmful micro-organisms by attacking their genetic code (DNA). The water is purified by running it through a water tight chamber which contains the UV lamp. A quarter sleeve houses the UV lamp where it remains separated from the water. As the water passes by the UV light, the microorganisms are exposed the the UV energy which destroys their DNA and causes them to lose their ability to reproduce and they simply die. This is a highly effective, environmentally-friendly, and chemical-free way to treat water and safeguard against bacterial and viral contamination of the water.

The most common application is for use in houses with shallow wells, which are prone to contamination. The UV unit provides the safest and most effective long-term solution.

Problem: Bacteria

Coliform Bacteria
It is not uncommon for a water test to detect the presence of coliform bacteria. In fact, most homeowners do not suspect or are not even aware of the presence of coliform bacteria until it is detected during a routine home inspection conducted for a real estate transaction. Bacteria are not seen, smelled, or tasted in water, so the only way to know if they are present is to have the water tested at a state certified laboratory. Coliform bacteria are:

  • common in the environment
  • generally not harmful
  • possibly indicative of a problem with the well, treatment system, or water distribution system

Symptom: Health Issues


Health issues may arise from using and consuming water containing bacteria. Fecal Coliform and Escherichia coli are bacteria whose presence indicates that the water may be contaminated with human or animal wastes. Microbes in these wastes can cause short-term effects, such as diarrhea, cramps, nausea, headaches, or other symptoms.
