Understanding Water Treatment Systems:

There are two main types of Water Filtration Systems available for home use:

Whole House Water Treatment Systems are also referred to as "Point-Of-Entry" (POE) systems.  These systems typically treat the water entering a residence. They are usually installed after the water meter if connected to a municipal water source, or after the pressurized storage tank if connected to a well.

"Point-Of-Use" (POU) systems treat water at the point of consumption, including the kitchen sink and refrigerator door drinking water and ice makers.   These types of systems are perfect for people who rent homes, apartments, condos and/or townhouses and young adults living in college dormitories.  They are also great for people who have Akaline water system in their homes as our Counter Top and Under Counter systems help to increase the output of these types of systems.   


The Hanish Water WaterCrest Whole House Physical Water Treatment Systems are specially designed to treat the specific challenges of consumers connected to a municipal source of water.  Many of the issues related to municipal water  can be elevated chlorine levels, boil water alerts due to aging infrastructure including water main breaks, and contamination from deteriorating delivery systems.  

We also offer technologies to treat well water, community well systems, and rain water systems.  Because of the unique nature of these types of systems, please contact one of our Hanish Water Water Technology Experts to discuss your specific needs.


Our Whole House Point-Of-Entry and Point-Of-Use water treatment systems use no electricity because they have no moving parts, require no chemicals or salt, do not backwashing hundreds of gallons of contaminated water back into the environment, and are more reliable than traditional water treatment or softening technology, making the Hanish Water Systems a good choice for rural water treatment applications.  Our water treatment systems treat for taste, odor, color, bacteria, cyst, virus, particulates, and even DNA and Pharmaceuticals which are slowly and increasingly entering our water systems.

Types of Water Contamination
Municipal Water


The sources of city water (both tap and bottled water) include rivers, lakes, streams, ponds, reservoirs, springs and wells. As water travels over the surface of the land or through the ground, it dissolves naturally-occurring minerals and can pick up substances resulting from the presence of animals or from human activity.

Contaminants that may be present in source water include:

Microbial contaminants, such as viruses and bacteria, which may come from sewage treatment plants, septic systems, agricultural livestock operations, and wildlife. 

Inorganic contaminants, such as salts and metals, which can be naturally-occurring or result from urban storm water runoff, industrial or domestic wastewater discharges, oil and gas production, mining or farming. 

Pesticides and herbicides, which may come from a variety of sources such as agriculture, urban storm water runoff, and residential uses. 

Organic chemical contaminants, including synthetic and volatile organic chemicals, which are by-products or industrial processes and petroleum production, and can also come from gas stations, urban storm water runoff, and septic systems. 

To ensure tap water is safe to drink the EPA prescribes regulations which limit the amount of certain contaminates in water provided by public water systems. FDA regulations establish limits for contaminants in bottled water which must provide the same protection for public health. All drinking water, including bottled water, may reasonably be expected to contain at least small amounts of some contaminants. The presence of contaminants does not necessarily indicate that the water poses a health risk. 

Infants and young children are typically more vulnerable to lead in drinking water than the general population. It is possible that lead levels at your home may be higher than at other homes in the community because of materials used in your home's plumbing. If you are concerned about elevated lead levels in your home's water, you may wish to have your water tested. 

Some people may be more vulnerable to contaminants in drinking water than the general population. Immuno-compromised persons such as those with cancer undergoing chemotherapy, persons who have undergone organ transplants, people with HIV/AIDS or other immune system disorders, some elderly, and infants can be particularly at risk from infections. These people should seek advice about drinking water from their health care providers.

Well Water

Well water should be tested every year. Drinking contaminated water is a health risk. Some contaminants cannot be seen, smelled or tasted. The most common of these in well water is bacteria. 

Private well users are responsible for testing their own water. If you don’t own your home but you use a private well, talk with your landlord about having your water tested. You can always take a water sample yourself and have it tested. Simply contact us and we will help you. 

You should also test your water when: 

You notice a change in your water, such as taste, color or smell. 

Your well has been flooded. 

You replace any part of your well system. 

Someone in your household is pregnant, nursing or has an unexplained illness and you suspect your water may be at risk. 

You hear that a neighbor’s water is contaminated. 

You live near industrial or agricultural activities. 

If you have had previous contamination problems or are concerned about specific contaminants, you may want to test your well water more often. 

When in doubt, contact Hanish Water. 

Another option is to install a Hanish Water system designed to remove contaminants from your water.

Coliform tests usually come back as SATISFACTORY or UNSATISFACTORY. If you receive an UNSATISFACTORY report, it may be contaminated. Do not drink the water until it tests SATISFACTORY. Find a different and safe drinking water supply. The immediate action would be either use bottled water, or boil your water for drinking and food preparation. This also includes water used for making ice or coffee, brushing teeth and washing fruits and vegetables you eat raw.
