The highly corrosive environments found in the municipal wastewater market make it a core industry for Sauereisen and our corrosion-resistant materials. We have decades of experience in delivering quality products and services that provide dependable solutions for these aggressive environments while helping to preserve municipal assets.

Whether its restoration or new construction, Sauereisen’s wastewater products are utilized in both collections systems and treatment plants. We also address the environmental and economic challenges posed by water inflow and infiltration. Typical structures include manholes, lift stations, headworks, grit chambers, clarifiers, digesters, sludge tanks/houses, chlorine contact cells and ozonation chambers.

The environmental conditions of wastewater collection systems and treatment plants are similar, yet different. Both areas deal with the threat of corrosion due to microbiological conditions. In either case, the presence of sulfuric acid and abrasion requires protection.

The application conditions are likely to be quite different, however. The deterioration and dimensions of the average manhole or lift station likely dictates a greater degree of substrate repair or a different installation method. Likewise, treatment plants are more likely to seek materials with either a greater flexibility or gloss.

Sauereisen's SewerGard polymer lining is available in several variations. Diversity of reinforcement, thickness, and application method positions Sauereisen to recommend the ideal formulation for specific service conditions.

Sauereisen recognizes the need to incorporate an “engineered systems” approach to specifications. Substrate repair materials and protective linings go hand-in-hand, but few companies possess the solutions, much less the understanding, to offer both.

A deteriorated municipal structure may be plagued with water infiltration issues, exposed aggregate, open mortar joints, or all of the above. The same structure isn't going to realize a significantly prolonged service life from a simple “patch job”. Sauereisen specializes in restoring structural integrity and enabling chemical resistance through protective linings of low permeability.
