• Groundwater.

Tap Water

Although PDAM water has gone through a treatment process, its quality can still vary and it faces several challenges:

• Sewage Contamination: The river water that feeds the PDAMs in many of Indonesia's major cities is often polluted by household and small industrial waste. This can affect the quality of water distributed to homes.
• Chlorine Residual: PDAMs use chlorine for disinfection, however excessive chlorine residual can cause unwanted odor and taste in the water.
• Quality Fluctuations: The quality of PDAM water can fluctuate depending on the season and the condition of the water source, which sometimes requires adjustments in treatment at the household level.

Refillable Water

The use of refillable water in gallons has become a trend in Indonesia, but it also comes with its own risks:

• Microplastic Contamination: The refilling process and repeated use of plastic gallons can increase the risk of microplastic contamination of drinking water.
• Varying Quality: Different treatment standards between refill water depots can result in significant variations in water quality.
• Water Quality Varies.
• Risk of Bacterial Contamination: If the treatment and packaging process is not done properly, refill water can be contaminated with bacteria.
• Risk of Bacterial Contamination.

Facing these challenges, many households in Indonesia are starting to consider more comprehensive water treatment systems. One solution that is gaining popularity is the whole house water treatment system. These systems are installed at the point of water entry into the home, from either groundwater or PDAM sources, and can effectively address a wide range of water quality issues.

For groundwater, the treatment system usually involves several steps:

1. Initial filtration to remove coarse particles.
2. Use of specialized media such as Birm or manganese greensand to remove iron and manganese.
3. Water softening using a softener system to address hardness issues.
4. Disinfection using chlorine or ultraviolet (UV) systems to remove bacteria.

For PDAM water, the treatment system may be simpler, focusing on:

1. Filtration using activated carbon to remove chlorine and improve water taste and odor.
2. Water softening if required.
3. Additional disinfection using UV if a higher level of safety is desired.

For households that want very high quality drinking water, the use of a point-of-use reverse osmosis (RO) system such as the Pentair Merlin RO can be an ideal solution. RO systems are capable of removing almost all contaminants, including microplastics, providing premium quality drinking water.
