However, have you ever experienced a situation where the water coming out of your home's faucet has an unpleasant odor? If yes, you are not alone. Many households in Indonesia face similar issues, and this could be an indication of a problem with the quality of water you use.
Understanding the Household Water Treatment System
Before we dive into the issue of odorous water, it is important to understand how a household water treatment system works. In general, these systems consist of a few key components:
- Water source: Can be well water or water from a municipal water supply system (PDAM).
- Storage tank: To store water before it is further treated.
- Storage tanks.
- Pump: To convey water from the source to the treatment system.
- Pumps.
- Filters: To remove dirt, sediment, and other contaminants.
- Filters.
- Water softener system: To reduce water hardness if required.
- Water softener system.
- Disinfection system: Usually uses chlorine or UV to kill harmful microorganisms.
- Disinfection system.
- Distribution system: Pipes and faucets to deliver water throughout the house.
- Distribution system.
Household water treatment systems can vary depending on the water source used and the desired water quality. For example, a home using well water may require a more complex treatment system compared to a home using PDAM water.
Causes of Odorous Water in Household Water Treatment Systems
Smelling water can be caused by a variety of factors. Here are some common causes:
1. Bacterial Contamination
One of the main causes of smelly water is bacterial contamination. Anaerobic bacteria, which grow in conditions without oxygen, can produce hydrogen sulfide gas that has a rotten egg-like odor. Bacterial contamination can occur due to leaks in the septic system or the introduction of polluted surface water into the well.
2. High Mineral Content
Water with high mineral content, especially iron and manganese, can produce a metallic or rust-like odor. This is often the case with well water that has not been properly treated.
3. Algae and Other Microorganisms
Algae growth in storage tanks or distribution pipes can produce an earthy or musty odor. In addition, some types of cyanobacteria can also produce compounds that cause unpleasant odors, such as geosmin and MIB (2-methylisoborneol).
4. Excess Chlorine
While chlorine is important for disinfection, overuse can cause a swimming pool-like odor in drinking water. Ironically, some people take chlorine odor as a sign of safe water, when a strong odor could signal a problem in the chlorination process.
5. Problems with the Water Heating System
Sometimes, unpleasant odors can come from the water heating system. The reaction between magnesium and aluminum on the anode rod in a water heater can produce hydrogen gas, which has an odor like rotten eggs.
6. Chemical Contamination
In some cases, odors in water can be caused by chemical contamination from industry or agriculture. For example, pesticides or industrial waste contaminating groundwater sources.
The Impact of Odorous Water on Health and Comfort
Aodorous water is not only aesthetically disturbing, but it can also have serious impacts on health and comfort. Here are some of the impacts to consider:
1. Health Risks
While not all odorous water is harmful to health, some contaminants that cause odors can carry health risks. For example, coliform bacteria often associated with septic odors can cause gastrointestinal diseases. In addition, some types of blue-green algae (cyanobacteria) can produce toxins that are harmful to humans and animals.
2. Comfort Disorder
Smelling water can greatly interfere with daily comfort. Unpleasant odors while bathing, washing clothes, or even while drinking water can significantly reduce quality of life. It can also cause discomfort when receiving guests at home.
3. Aesthetic Issues
Smelling water is often accompanied by other aesthetic issues such as abnormal color or turbidity. This can lead to stains on clothing, sanitary equipment, and kitchen utensils.
4. Decrease in Property Value
Homes with persistent odorous water issues may experience a decrease in property value. Potential buyers or tenants may think twice before choosing a property with water quality issues.
5. Increased Cost
To address odorous water issues, homeowners may need to incur additional costs for water treatment systems or regular purchases of bottled water.
Solutions for Dealing with Odorous Water
Facing an odorous water problem is unpleasant, but there are various solutions that can be implemented. Here are some steps you can take:
1. Identify the Odor Source
The first step is to identify the source of the odor. Does the odor appear only with hot or cold water? Is the odor consistent or only present at certain times? The answers to these questions can help determine the cause and appropriate solution.
2. Water Quality Test
Conduct a thorough water quality test. This will help identify specific contaminants that may be causing the odor. You can contact your local water testing lab or use a home water testing kit.
3. Proper Filtration System
Depending on the water testing results, you may need to install a suitable filtration system. Some options include:
- Activated carbon filter: Effective for removing chlorine odors and other organic odors.
- Active carbon filter.
- KDF (Kinetic Degradation Fluxion) filter: Good for removing iron, manganese, and hydrogen sulfide.
- KDF (Kinetic Degradation Fluxion) filter.
- Reverse Osmosis (RO): A highly effective system for removing a variety of contaminants, including those that cause odors.
- Reverse Osmosis (RO).
The Pentair Merlin Reverse Osmosis System is one option that can be considered for drinking water treatment in households.
4. Proper Disinfection
If the odor problem is caused by bacterial contamination, make sure your disinfection system is working properly. This could involve adding the right amount of chlorine or using a UV system.
5. Aeration
For odor problems caused by dissolved gases such as hydrogen sulfide, aeration can be an effective solution. Aeration systems help remove these gases from the water.
6. Water System Routine Maintenance
Perform routine maintenance on your water treatment system. This includes cleaning the storage tank, changing filters regularly, and checking for leaks in the pipes.
7. Septic System Repair
If the odor is caused by a septic system leak, immediate repairs are required to prevent further contamination.
8. Consultation with Experts
If the problem is persistent or you are unsure of the steps to take, consult a water treatment expert. They can provide more specific advice based on the condition of the water and system in your home.
Comprehensive Household Water Treatment System
To address a variety of water quality issues, including odors, a comprehensive household water treatment system may be necessary. Here are the components to consider:
1. Pre-filtration System
This system removes large particles and sediment from the water. A sediment filter or Pentair Pentek filter cartridge can be a good choice for this stage.
2. Water Softener System
If your water has high levels of hardness, a water softening system can help reduce the content of minerals such as calcium and magnesium. This not only improves water quality but also protects household appliances from damage due to hard water.
3. Activated Carbon Filtration System
Activated carbon filters are highly effective in removing odor, taste, and organic contaminants. Coal-based activated carbon from Calgon is one option that can be considered.
4. Reverse Osmosis (RO) System

Questions and Answers
Q1: Is odorous water always hazardous to health?
A1: Not always. Some odors, such as a mild chlorine smell, may be harmless and even indicate water that has been properly disinfected. However, strong or unusual odors can be a sign of harmful contaminants such as bacteria or chemicals. Therefore, if you smell an unusual odor in your water, it's best to have it tested for water quality to ensure its safety.
Q2: How can I tell the difference between an odor caused by the plumbing system and an odor coming from the water source?
A2: To tell the difference, you can do a simple test. Take a sample of water directly from the source (for example, from the main pipe before it enters the home system) and compare it to the water from the faucet inside the house. If the odor is only present in the water from the tap, the problem is probably with the plumbing system or appliances inside the house. If the odor is already present in the sample from the source, then the source water is the problem.
Q3: Are Reverse Osmosis (RO) systems effective for removing all types of odors in water?
A3: RO systems are very effective at removing a wide range of contaminants, including many that cause odors. However, some dissolved gases such as hydrogen sulfide (which causes rotten egg odors) may not be completely removed by RO. In cases like this, a combination of RO with an aeration system or activated carbon filter may be required for optimal results.
