Wilo Brazil supplies pumps for raw water intake from the Guarani Aquifer

São Jose do Rio Preto. The reliable supply of drinking water is one of the fundamental pillars for a functioning society. Ever scarcer resources, increasing water requirements and fluctuating groundwater levels are the challenges here. For water extraction, system solutions are required that enable optimum adaptation to the operating conditions. Wilo offers high-quality, future-oriented solutions for this area of application that actively support our customers in the fundamental task of a cost and energy-efficient water supply.

The city of São José do Rio Preto has about 465,000 inhabitants and is in the Guarani Aquifer reservoir region, which is considered one of the largest freshwater underground reservoirs on the planet. According to Trata Brazil, in 2020 the city ranked 4th among the municipalities with the best sanitation and the lowest rate in the state of São Paulo. SeMAE currently produces 55 million m3 / year of water, of which the Guaraní aquifer, with eight wells, produces 13.5 million m3 / year.
