Household Water Filters

Basic Water Needs (BWN) is widely recognized for its impact in developing, producing and distributing water purification and conservation products; creating access to safe drinking water for everyone.

Over the last 15 years, BWN has supplied our innovative Dutch-designed Tulip water filters to more than 3,000,000 people worldwide, offering safe and durable drinking water products that are simple to use and last for thousands of liters. 

Submersible Solar Pumps

Situated at the heart of the water-food-energy nexus, the solar water pump plays a critical role in improving the incomes and resilience of rural households while unlocking environmental benefits.

Approximately 95% of farmland in Sub-Saharan Africa, 60% in South Asia and 65% in Central America is rainfed, reliant on unpredictable weather patterns. Solar water pumps—a clean, modern irrigation solution—have the potential to increase yields by two to three- fold, depending on crop and climate.

Our contribution to a sustainable environment

Notably, both our solar pumps and water filters contribute to the reduction of CO2 emissions, aligning with environmental sustainability goals. These eco-friendly solutions are actively integrated into programs that incentivize carbon credits, supporting global efforts to combat climate change.

Through the Solarimpulse Foundation it has been calculated that 1 water filter avoids the emission of about 0,4 tCO2 – 1,7 tCO2 per filter per year, while emissions caused by manufacturing and transport of the filters is negligible. Emissions are avoided as no non-renewable biomass is needed to boil water, the mainstream alternative. A conservative estimate therefore is that through the usage of the water filters alone 1,200,000 + tons of CO2 have been diverted.

This is one of the reasons why the Tulip Table Top has been awarded the Solar Impulse Efficient Solution Label for two consecutive periods.
