Tap water quality in Saitama, Saitama-ken? Is it safe to drink?
The tap water in Saitama, Saitama-ken, Japan is considered safe for consumption and adheres to national water quality regulations. The local water authorities are committed to maintaining high standards for public health.
Water Quality Issues in Saitama:
- Source: The water in Saitama is primarily sourced from surface water bodies such as rivers and reservoirs, which are closely monitored for quality.
- Testing: Regular testing ensures compliance with standards set by the Japanese Ministry of Health, Labor, and Welfare, addressing both chemical and biological contaminants.
- Hardness: Saitama's water is generally soft, but mineral content can vary depending on the source, occasionally leading to minor scaling in appliances.
- Concerns: While the water is deemed safe, residents sometimes report a chlorine-like taste, making water filters a popular option to enhance flavor and remove any residual impurities.
Overall, while Saitama's water quality is reliable, residents are encouraged to use water filters and softeners. These devices can improve water taste and address any potential hardness issues, ensuring better water quality for household use and consumption.

What do we do? How do we help?
We have developed the TDSBot, an inexpensive IOT device that monitors, in real time, the Incoming and Outgoing TDS levels, temperature, flow rate and cumulative volume of water filtered. Easy to install, it works with all water purifiers including, sediment, GAC, Carbon, Micro, Ultra, Nano and Reverse Osmosis water filters. Key benefits:
- Know the incoming and filtered water quality in real time.
- Know the volume of water filtered by day, week, month and total.
- Know in advance when to change filter cartridges. Too often we tend to realize that they need changing after the water purifier has stopped working or worse, when the water smells bad.
- Change filters only when needed. Sometimes filters perform longer than their standard life due to better incoming water or lower usage. Reduce waste and save money.
- Quality data collected is aggregated to show real time water quality data to all the community.
TDSBot can be installed on water purifiers from Pentair, Culligan, 3M, Brita, BWT, iSpring, and most other brands. Supports sediment, GAC, Micro, Ultra, Nano and Reverse osmosis filters. It can remotely monitor filters attached to Coffee machines, Ice makers, soda fountains, water dispensers, ovens, laundry & dish washing, car wash found at Cafes, convenient stores, healthcare facilities, hotels, offices, restaurants, colleges, schools, hydroponic systems, and many more.

Learn About Water Quality
* A definition specific to a few codes is that “Safe drinking water” means water that meets all primary and secondary drinking water standards. Drinking water standards are set based on potential health impacts and also take into account the cost to meet the drinking water standard. Also, the U.S. Environmental Protection Agency (EPA) defines drinking water as safe when humans can drink it with low risk of immediate or long-term harm to your health. Although there may be health risks associated with certain contaminants found in drinking water not all contaminants are necessarily harmful.
