Wastewater Collection & Treatment Projects

Xypex products play a key role in the prevention and treatment of problems common to the sanitary sewer collection system and the wastewater treatment plant.

Project Detail
  • Michigan Avenue Harrison Road Sewer Improvement

    East Lansing, Michigan, USA

    With increasing demands on its aging sewage infrastructure, the City of East Lansing, Michigan, undertook the rehabilitation of the Michigan Avenue and Harrison Road Sewer. 

    Project engineer Tetra Tech, Inc. specified that all precast concrete in the sanitary or combined sewage system incorporates Xypex Bio-San antimicrobial and crystalline waterproofing admixture, dosed at 1% of cementitious content. In addition, Xypex Admix C-500 crystalline waterproofing was specified for all areas in the sewer system not at risk of Microbial Induced Corrosion (MIC).

    Xypex Bio-San is a uniquely designed admixture for integral, long-term protection of concrete in harsh sewage conditions with levels of H2S that cause microbial induced corrosion (MIC). Bio-San combines potent antimicrobial protection along with the unique crystalline technology of the Xypex Admix C-Series.

    Bio-San contains bio-active mineral solids that become permanently fixed within the concrete matrix, impairing bio-film formation thus inhibiting the growth of acid-causing sewer bacteria such as Thiobacillus due to concentrations of H2S.

    The unique Xypex Crystalline Technology creates a permanent crystalline structure throughout the pores and capillary tracts of the concrete, providing waterproofing and enhanced chemical protection, including acid and sulphate resistance. Bio-San prevents microbial induced corrosion, stops infiltration/exfiltration of water, and provides acid and sulphate resistance, significantly extending the service life of concrete sewage collection systems and wastewater infrastructure.

    Xypex Admix C-500 is a chemical treatment for the waterproofing, protection and improvement of concrete. Added to the concrete mix at the time of batching, Xypex Admix simplifies the pre-casting and construction process.  

    Using crystalline admixture ensures waterproofing permanent protection and increased service life for the rehabilitated infrastructure.
