Tap water quality in Funchal, Madeira? Is it safe to drink?

Opening

Funchal, the vibrant capital city of Madeira, Portugal, is renowned for its stunning landscapes and unique subtropical climate. The quality of water in this picturesque city is of great importance, as it directly affects the well-being of its residents and the thousands of tourists who visit each year. Public and environmental health authorities ensure that the water supply meets the necessary safety and quality standards. However, like many places around the world, there are specific challenges that need to be addressed to maintain and enhance water quality in Funchal.

Water Quality Issues

Source: The primary water sources for Funchal are surface water bodies and groundwater reserves. These sources are susceptible to pollution from urban runoff, agricultural activities, and natural occurrences.

Testing: Regular testing is conducted to monitor the water quality in Funchal. Tests are designed to identify any contaminants such as bacteria, heavy metals, and chemical residues that could pose a risk to human health.

Standards: Water quality standards in Funchal are in line with the European Union regulations, which impose strict limits on the levels of various contaminants. Authorities consistently strive to comply with these standards, ensuring that any deviations are promptly addressed.

Water Hardness: The water hardness in Funchal can vary. Hard water, which contains high levels of calcium and magnesium, can lead to scaling in pipes and appliances, potentially reducing their lifespan.

Concerns: Some residents express concerns about the presence of chlorine and other treatment chemicals that could affect taste and smell. Additionally, potential contamination from outdated infrastructure remains a challenge.

Encouragement for Using Water Filters/Softeners

Given these challenges, using water filters or water softeners is highly recommended for households and businesses in Funchal. These devices can effectively reduce the concentration of heavy metals, chlorine, and other undesirable elements in the water supply. Filters improve taste and clarity, while softeners tackle problems related to water hardness. By installing such systems, residents can enjoy cleaner, safer, and more palatable water, enhancing their quality of life and protecting their plumbing systems from mineral buildup.

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.

* 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.
