Protecting Municipal Water Tanks With Surface Coating: A Guide

Water is crucial for the existence of life, but it can turn into a source of destruction if it’s not managed properly. If your municipal tank doesn’t have a water tank surface coating, it is likely to deteriorate, corrode, and nitrify.

Not only does this lead to water leakage, but these hazardous components also impact the safety and quality of water stored inside the tank and reduce the tank’s life expectancy.

Municipal Water Tank Designs and Their Risks

Municipal water tanks are designed to combat external influences that may deteriorate water quality and safety, such as changes in pH levels, mineral accumulation, algae, and bacterial growth.

Therefore, water tanks surface coatings are imperative for fiberglass municipal water tanks.

Fiberglass Surface Coating for Added Protection

Fiberglass surface coating.

Surface coatings protect the interior of the water storage tanks from mineral accumulation, corrosion, oxidization, and deterioration. The surface coating serves as a protective layer between the fiberglass walls of the tank and the water. While some fiberglass surface coatings also offer chemical resistance, it’s best to pick the type of coating according to the tank’s design, material, and the guidelines provided by the American Water Works Association.

Fiberglass reinforced plastic tanks, especially those installed above the ground, may require surface coatings on the interior walls, as well as the exterior walls for added protection against ultraviolet rays and excessive heat absorption. Without UV protection, the fiberglass tank’s exterior will begin to degrade, reducing the life expectancy of your tank.

Fiberglass surface coatings must be applied to municipal water tanks before they are installed for protection against:

  • Leaks
  • Sunlight
  • Cracks
  • Spalls
  • Abrasives in water
  • Tensile stresses
  • Freezing weather
  • Organic and inorganic deposits
  • Sunlight and ultraviolet rays
  • Chlorine losses in the water
  • Scale
  • High acidity or low pH levels in the stored water
