Tap water quality in Cotia, São Paulo? Is it safe to drink?

Located in the São Paulo Metropolitan Region, Cotia is a municipality that places a significant emphasis on public health and environmental quality. Water quality in Cotia is a critical subject as it directly impacts the daily lives of its residents and the local ecosystem.

Water Quality Issues

Cotia, like many urban areas, faces various water quality challenges stemming from diverse sources. Source: The primary sources of water in Cotia include local rivers and reservoirs. These sources are vulnerable to pollution from industrial waste, agricultural runoff, and untreated sewage which can introduce contaminants like heavy metals, pesticides, and bacteria.

Testing: Regular testing is conducted by local authorities to monitor the levels of contaminants in the water supply. These tests ensure that any deviations from accepted safety standards are promptly addressed. However, there are occasional reports of pollutants exceeding recommended thresholds.

Standards: The water quality standards in Cotia are aligned with both national and international guidelines to ensure safety for consumption. Regulations are in place to control permissible levels of substances such as chlorine, lead, and other additives, providing a baseline for safe drinking water.

Water Hardness: Another issue encountered in this region is water hardness, primarily due to the presence of calcium and magnesium in the water supply. Hard water can cause scaling in pipes and appliances, affecting their efficiency and longevity.

Concerns: Apart from hardness, there are concerns about episodic surges in microbiological contamination especially during rainy seasons when water sources are more likely to be contaminated by surface runoff.

Encouragement for Using Water Filters and Softeners

Considering these challenges, it is prudent for residents to utilize water filters and softeners in their households. Employing water filters can significantly reduce the presence of harmful contaminants and ensure that drinking water is safe and clean. Additionally, using water softeners can mitigate the effects of hard water, protecting household plumbing and appliances from damage.

  1. Health: Filters effectively remove bacteria, heavy metals, and other toxins.
  2. Appliance Longevity: Softeners enhance the efficiency and lifespan of household devices exposed to water.
  3. Cost Savings: Prevention of scale buildup reduces repair and energy costs over time.

By adopting these practices, the residents of Cotia can enjoy not only better-tasting water but also improved overall water-related infrastructure maintenance.

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.

Sustainability Impact Insights

TDSBot can generate a variety of sustainability data, including water usage metrics, identify areas of reducing water waste, leak detection and prevention, extend filter and equipment lifespan, predictive maintenance alerts to extend equipment life and reduce environmental impact.
Sustainability data can be easily showcased on your corporate website or publicly shared on your social media

* 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.
