Water treatment systems are designed to solve different problems, so consumers need to determine their specific treatment needs before shopping for a water treatment system. Some common issues consumers have that require water treatment include: water hardness, chemical and/or virus removal, UV treatment, well water quality and other water contaminants or pollutants.

As important as determining the problem you are trying to solve with a water treatment system is finding a reliable, professional installer. Due diligence on the consumer’s part is the best way to assure the success of any trade person’s installation or product.

Considerations when choosing a water treatment system

Contaminants targeted

Water treatment system companies are used by customers to remove a variety of different contaminants from their water. Note that, while some brands may use the term purify in their marketing materials, it is an inaccurate term to describe water treatment. Pure water is H2O, nothing else, which is a rare substance to encounter in its pure state.

  • Bacteria: Some water treatment companies focus on removing bacteria from water; these companies specialize in UV and other disinfection methods to kill bacteria that infects water and might make drinkers sick.
  • Minerals: There are also companies that target excess minerals in water, which cause the water to be hard. Companies that specialize in removing minerals often use a water softener system that uses an ion-exchange resin.
  • Multi-contaminant removal: Many water treatment systems companies offer services to remove a wide variety of materials from water. Some of the contaminants removed by water treatment systems include heavy metals from construction projects or damaged pipes that cause water to taste metallic, sediment that has gotten into a water supply through construction work and makes water appear muddy and brown and chlorine added by public water companies to disinfect water sources, which gives water a strong chemical taste.

Types of systems

There are multiple systems by which water treatment systems companies can remove contaminants from water.

  • Point of entry systems: Point of entry water treatment systems are able to treat all of the water entering a home or business and are installed after a water meter or storage tank.
  • Point of use systems: Some water treatment systems are used where people directly access the water, like a kitchen sink or a showerhead.
  • Multi-system companies: Multi-system companies perform several different types of water treatment, such as treating hardness with water softeners and removing pollutants. They can also treat by ionic exchange and Granular Active Carbon (GAC).

Source of water treatment

Water treatment systems companies can treat drinking and usable water that comes from a range of different sources.

  • Groundwater: Companies that treat groundwater specialize in technology for treating traditional water from the ground, which is a common type of water used for drinking and bathing in homes and businesses in many parts of the United States.
  • Brackish water: Brackish water is water that is part saltwater and part freshwater, which is often collected in estuaries. Brackish water can be collected and treated by water treatment companies to desalinate (Reverse Osmosis), then be used for things like irrigation and watering gardens and lawns.
  • Surface water: There are water treatment systems companies that specialize in treating surface water, which is collected rainwater or water at the top of a natural body of water. These companies collect the fresh surface water and use treatment to remove algae, bacteria and solids from the water in order to make it safe to drink or bathe with.

Technology utilized

Water treatment system companies use a range of different technologies to treat and condition water for customers.

  • Filtration: Water filtration cleans water by trapping contaminants in a filter, which then absorbing or breaking the contaminants down.
  • Ultraviolet technology: Companies that use UV technology utilize UV rays to disinfect water and kill bacteria in it.
  • Reverse osmosis: There are some water treatment companies that use reverse osmosis, which is a process in which dissolved inorganic solids (such as salts) are removed from a solution (such as water). This is accomplished by household water pressure pushing the tap water through a semipermeable membrane.


In water treatment, eco-friendly means little or no effluent wastewater is required in treating the water. Water softeners are not eco-friendly even if they claim they are. Everything is relative, but all water softeners have wastewater that is hazardous to most anything, (salt).  Water filtration companies differ from one another based on how eco-friendly their filtration practices are.

  • Green filtration companies: There are some water filtration companies that filter water with the environment in mind, and they only use green materials and products.
  • Eco-friendly options: Some water treatment systems companies offer customers eco-friendly products and services, like salt-free treatments, which use significantly less water in order to get pure water than a traditional salt-based purification system.
  • Traditional water treatment systems companies: Many water treatment systems companies use traditional technology and products, and they are not particularly focused on environmental-friendliness.

Customer maintenance requirements

Water treatment systems differ from one another based on how much maintenance a customer must perform on the system. Performing proper maintenance on your water treatment system is a must if you want it to continue working.

  • No maintenance required: Some water treatment companies handle all maintenance for water treatment systems, including installation and regular check-ins and updates.
  • Minimal maintenance: There are some water treatment systems that require minimal maintenance from customers, like checking filters to see if they are clogged or dirty or watching monitors on filters that change color when they are ready to be replaced.
  • Customer maintained: Customers often have to have complete control over the maintenance of their water filtration system, like replacing filters regularly.

Types of water treatment system companies

Commercial water system companies

Some water treatment system companies are completely devoted to treating water for large scale businesses, like hotels and office towers. These companies handle large projects for big facilities.

Residential water treatment companies

Residential water treatment companies specialize in treating water for customers that live in homes. They can set up systems for a whole home, for different faucets or water sources within a home.

Water treatment product companies

There are some water treatment companies that simply sell individual products for water treatment. Consumers can purchase these products, like drinking water filters that can be directly installed onto faucets and add-on showerhead softeners. They can use them as needed to filter and treat water.

Water softening companies

Water softening companies are fully focused on treating hard water, which is water that has a high mineral count, can taste odd and leave scale behind on shower walls, bathtubs and sinks. These companies can install water softeners for both residential and business customers.

People who use a water treatment system

Homeowners with hard water

Homeowners with hard water have water with excess minerals and impurities in it. Water treatment systems help soften water to make it more palatable and better to use.

Homeowners near a compromised water supply

Sometimes a water supply can become compromised because of natural disasters or industrial accents. Water treatment systems companies can help clean potentially compromised water and ensure that it is safe and healthy to drink.

Managers of large commercial properties

Developers or managers have to manage the water supply of large business complexes. Water treatment systems on a commercial scale can help clean water for a large number of people.

Rural customers using well water

Rural customers often don't have access to fresh water lines. Customers who use well water can use water treatment systems companies to ensure their well water is safe and clean to drink.
