Water Treatment System For Houston Homeowners
Water treatment systems are a relatively recent addition in the homes of many people. The amount of publicity about levels of contaminants in household water systems has increased, particularly in the last decade. Now, homeowners and renters alike are choosing to ensure that the water they use to drink, cook and bathe in is free from contamination.
This video covers different methods for treating water using filters, purifiers or chemicals and how they apply to backpacking.
Drinking water supplies in the United States are among the safest in the world. However, even in the U.S., drinking water sources can become contaminated, causing sickness and disease from waterborne germs, such as Cryptosporidium, E. coli, Hepatitis A, Giardia intestinalis, and other pathogens.
Drinking water sources are subject to contamination and require appropriate treatment to remove disease-causing agents. Public drinking water systems use various methods of water treatment to provide safe drinking water for their communities. Today, the most common steps in water treatment used by community water systems (mainly surface water treatment) include:
Coagulation and Flocculation
Coagulation and flocculation are often the first steps in water treatment. Chemicals with a positive charge are added to the water. The positive charge of these chemicals neutralizes the negative charge of dirt and other dissolved particles in the water. When this occurs, the particles bind with the chemicals and form larger particles, called floc.
During sedimentation, floc settles to the bottom of the water supply, due to its weight. This settling process is called sedimentation.
Once the floc has settled to the bottom of the water supply, the clear water on top will pass through filters of varying compositions (sand, gravel, and charcoal) and pore sizes, in order to remove dissolved particles, such as dust, parasites, bacteria, viruses, and chemicals.
After the water has been filtered, a disinfectant (for example, chlorine, chloramine) may be added in order to kill any remaining parasites, bacteria, and viruses, and to protect the water from germs when it is piped to homes and businesses.
Water may be treated differently in different communities depending on the quality of the water that enters the treatment plant. Typically, surface water requires more treatment and filtration than ground water because lakes, rivers, and streams contain more sediment and pollutants and are more likely to be contaminated than ground water.
Some water supplies may also contain disinfections by-products, inorganic chemicals, organic chemicals, and radionuclides. Specialized methods for controlling formation or removing them can also be part of water treatment. To learn more about the different treatments for drinking water, see the National Drinking Water Clearinghouse’s Fact Sheet Series on Drinking Water Treatments.
To learn more about the steps that are taken to make our water safe to drink, visit the United States Environmental Protection Agency’s (EPA) Public Drinking Water Systems webpage. To learn more about the 90+ contaminants EPA regulates and why, visit EPA’s Drinking Water Contaminants page.
Community water fluoridation prevents tooth decay safely and effectively. Water fluoridation has been named one of 10 great public health achievements of the 20th century 1. For more information on the fluoridation process and to find details on your water system’s fluoridation, visit CDC’s Community Water Fluoridation page.
Consumer Confidence Reports
Every community water supplier must provide an annual report, sometimes called a Consumer Confidence Report, or “CCR,” to its customers. The report provides information on your local drinking water quality, including the water’s source, contaminants found in the water, and how consumers can get involved in protecting drinking water.

Household Water Treatment
Even though EPA regulates and sets standards for public drinking water, many Americans use a home water treatment unit to:
Remove specific contaminants
Take extra precautions because a household member has a compromised immune system
Improve the taste of drinking water
Household water treatment systems are composed of two categories: point-of-use and point-of-entry (NSF). Point-of-entry systems are typically installed after the water meter and treat most of the water entering a residence. Point-of-use systems are systems that treat water in batches and deliver water to a tap, such as a kitchen or a bathroom sink or an auxiliary faucet mounted next to a tap.
The most common types of household water treatment systems consist of:
Filtration SystemsA water filter is a device which removes impurities from water by means of a physical barrier, chemical, and/or biological process.
Water SoftenersA water softener is a device that reduces the hardness of the water. A water softener typically uses sodium or potassium ions to replace calcium and magnesium ions, the ions that create “hardness.”
Distillation SystemsDistillation is a process in which impure water is boiled and the steam is collected and condensed in a separate container, leaving many of the solid contaminants behind.
DisinfectionDisinfection is a physical or chemical process in which pathogenic microorganisms are deactivated or killed. Examples of chemical disinfectants are chlorine, chlorine dioxide, and ozone. Examples of physical disinfectants include ultraviolet light, electronic radiation, and heat.
Water Treatment Importance
Treatment of water is so important that we can avoid many possible water-borne diseases like cholera, typhoid, jaundice and so on. It’s true that water-borne infections are responsible for more than 80% of the diseases in all over the world.Whenever there is contamination of drinking water sources and water logging after rain there is in an outbreak of infection.
