Brazil’s Innovative Approach: Xypex Protects Pinheiros Sewage Pumping Station

The Estação Elevatória de Esgoto Pinheiros, a vital wastewater pumping station in São Paulo, Brazil, faced a significant challenge: advanced concrete deterioration due to microbial induced corrosion (MIC). This is a common problem in sewage environments, where bacteria produce sulfuric acid that attacks concrete. To address this, an innovative solution was implemented, showcasing Brazil's leadership in sanitation engineering.

The Menace of MIC

Microbial induced corrosion (MIC) is a serious threat to the longevity of concrete structures in wastewater facilities. Bacteria thrive in these environments, producing corrosive substances that degrade the concrete, leading to costly repairs and reduced service life.

Xypex Bio-San C500: A Dual-Action Solution

To combat MIC and ensure the long-term integrity of the Pinheiros Sewage Pumping Station, Xypex Bio-San C500 was chosen. This unique product offers a dual-action approach:

  • Antimicrobial Protection: Xypex Bio-San C500 contains bioactive mineral solids that inhibit the growth of acid-causing bacteria, such as Thiobacillus, preventing MIC.
  • Crystalline Waterproofing: Xypex’s crystalline technology creates a permanent, waterproof barrier within the concrete. This not only protects against water infiltration but also enhances the concrete’s resistance to sulfates and sulfuric acid attack.

A First in Brazil

The Pinheiros project marked a significant milestone as the first in Brazil to proactively combat the biogenic attack of concrete. The Xypex-treated concrete was cast in segmental ring sections to restore the concrete cover and surface while the station remained in operation, minimizing disruption.  

Lasting Impact

The successful application of Xypex Bio-San C500 at the Pinheiros Sewage Pumping Station has not only protected this critical infrastructure but has also set a new standard for sanitation projects in Brazil. This project demonstrates the effectiveness of proactive measures and advanced technologies in ensuring the durability and longevity of wastewater treatment facilities. The revitalization of Estação Elevatória de Esgoto Pinheiros water treatment plant showcases how innovation and engineering proficiency can overcome challenges. The combination of Xypex technology with strategic repair methodologies saved the station from further deterioration, significantly extending its useful service life
