Wastewater Treatment Coatings and Linings

Coatings and linings for wastewater treatment facilities

WHAT are WASTEWater Treatment Plant Coatings and Linings?

Wastewater environments go hand in hand with the presence of sulfuric acid, chlorine, ammonium, sodium, sulfates and other chemicals, which can cause significant problems for facility managers. Storage containers, tanks, pipes, intake structures, basins, clarifiers, vessels and other steel or concrete infrastructure in industrial and municipal wastewater treatment facilities are subject to a range of constant abuse from chemical exposure, abrasions, impacts and more. Without adequate protection, these assets can be damaged, resulting in everything from cracks, corrosion and leakage to costly replacement, extensive maintenance or other far-reaching issues. 

Sherwin-Williams wastewater treatment lining and coating solutions offer superior chemical resistance and long-lasting protection to concrete and steel structures. Whether the substrate is exposed to environmental hazards, corrosive elements, chemical attacks or atmospheric damage, Sherwin-Williams coatings and linings prevent corrosion and ensure the long-term service life of the wastewater treatment structure.

  • Extends the total service life of treatment facilities and equipment
  • Protects against chemical degradation
  • Reduces out-of-service time for critical assets
  • Protects against leaks
  • Protects against contamination
  • Protects concrete, steel and ductile iron

Anti-Corrosive & Chemical Resistant Wastewater Treatment Linings and Coatings

Storage containers, tanks, pipes, intake structures, basins, clarifiers, vessels and other steel or concrete infrastructure in industrial and municipal wastewater treatment facilities are subject to a range of constant abuse from chemical exposure, abrasions, impacts and more. These elements can corrode, erode, crack and otherwise damage the concrete or steel, leading to leakage, reduced lifespan, costly maintenance and other wide-reaching consequences—unless they are adequately protected.

Sherwin-Williams protective wastewater treatment linings and coatings offer:

  • Superior resistance to hydrogen sulfide, gas and microbiologically-induced corrosion
  • Versatile application processes to address jobsite access
  • Compatibility with all concrete rehabilitation construction materials

Wastewater Treatment Linings and Coatings for a Long-Lasting, Durable Finish 

Sherwin-Williams wastewater treatment coating and lining solutions are extremely durable as well as resistant to wear and tear, impacts and abrasions. They fully adhere to the concrete or steel substrate, serve as a functional protective barrier and are made to withstand the harsh conditions of wastewater environments. Sherwin-Williams epoxy and polyurethane coatings and linings meet the demanding needs of wastewater treatment facilities and offer long-term protection.

Our municipal and industrial coatings for wastewater treatment and collection systems as well as our pipe, tank and container linings create a barrier between the stored or transported liquid and the substrate surface. Thanks to the significant protection, durability, anti-corrosive and chemical resistant properties of Sherwin-Williams coating and lining products, maintenance requirements are significantly reduced. After installation, you can increase the lifespan of the infrastructure in your wastewater treatment facility and enjoy the benefits for years to come.
