What is SDW?

Safe Drinking Water For All

Hello, we are the Safe Drinking Water For All - SDW, a socio-environmental impact startup that emerged on the need to reduce the problems caused by waterborne diseases through innovative and sustainable solutions for water treatment. Our focus is on people who have difficulty accessing drinking water in regions such as the Northeastern of Bahia, but in addition, the proposal extends to the development of products for different publics that have water demand and whose current solutions can not adequately supply their Needs.


Provide more health to people with sustainable and innovative solutions for water tratment.


The problem

Scarcity of drinking water on the planet

Currently, almost 700 million people still do not have access to drinking water. The United Nations estimates that by 2025 up to 1.8 billion people will live in countries or regions with extreme water shortages. About two-thirds of the world's population will be affected by the consequences of our global water scarcity. About 3 million people will die every year as a result of water-related diseases - that is, around 10,000 people every day - mostly children under five.

We have the solution!

An innovative and sustainable product




Solar water disinfection device

Pathogenic microorganisms are vulnerable to two effects of sunlight: radiation in the spectrum of UV-A light (wavelength 320-400nm) and heat (water temperature rise).

That is why SDW is developing Aqualuz: a social technology for water purification (for human consumption) using solar energy and sisal fiber filter. The Aqualuz is an easily adaptable solar water filtration and disinfection device composed of an inlet filter filled with flexible sisal fibers (or other material), a reservoir made of polyethylene and an electrical monitoring system that can be adapted to many water sources that have microbiological contamination, and is ideal for rainwater harvesting cisterns.
