Maintenance of a GS Tanks in Africa - Galvanized Sectional Panels Tanks

Maximizing the Lifespan of Sectional Steel Water Tanks:

A Comprehensive Guide to Maintenance


Sectional steel water tanks are essential components of water storage systems, providing a reliable and efficient solution for various applications. To ensure the longevity and optimal performance of these tanks, proper maintenance is crucial. This article explores a comprehensive set of maintenance tips aimed at prolonging the lifespan of sectional steel water tanks.

Regular Inspection:

Regular inspections form the cornerstone of effective tank maintenance. Visual assessments should be conducted at least twice a year to identify potential issues such as corrosion, leaks, or structural damage. Pay particular attention to vulnerable areas like seams, joints, and coating integrity. Early detection allows for prompt intervention, preventing minor problems from escalating into major concerns.

Savanna Tanks, as an industry leader for more than 35 years have found African conditions to be specifically difficult. To counter this we have tried to out design certain common maintenance issues.

Corrosion Prevention:

Corrosion is a primary threat to sectional steel water tanks, compromising structural integrity and water quality. Implementing corrosion prevention measures is imperative. Apply a high-quality, corrosion-resistant coating during the tank's construction, and reapply it as needed based on the manufacturer's recommendations. Additionally, inspect the tank's surroundings for potential corrosive elements, such as chemicals, fertilizers, or industrial pollutants, and mitigate their impact promptly.

This is again another overlooked factor - A water analysis of the stored water is so important. It's important to appericate the bracing system of a steel tank is internal. You might want to have a look at the following video to get a better understanding

Cleaning and Sanitization:

Regular cleaning and sanitization are vital for maintaining water quality and preventing the growth of algae, bacteria, and other contaminants. Remove sediment and debris from the tank's floor, ensuring that the water remains clear and free from impurities. Cleaning should be done annually or as per local health regulations, utilizing safe and approved methods to avoid damage to the tank's interior.

The above is naturally some of the obvious factors , but we need to mindful of other issues like overgrown tank bases are excellent places for Snakes / Birds / Rodents.

Currently, in Savanna Tanks we are considering now introducing bird deflectors to deter the tank roofs to be landing stations.

Adequate Ventilation:

Proper ventilation is crucial for preventing the buildup of moisture within the tank. Inadequate ventilation can lead to the formation of condensation, promoting corrosion and compromising water quality. Ensure that ventilation systems are functioning correctly, and address any issues promptly to maintain optimal conditions inside the tank.

  1. Structural Integrity Checks:

Regularly assess the structural integrity of the tank, focusing on elements such as bolts, nuts, and panels. Tighten loose bolts and nuts to prevent water leakage and potential structural failure. Conduct periodic load tests to evaluate the tank's capacity and verify that it meets the required safety standards. Address any identified issues promptly to ensure the tank's continued reliability.

Proper pre-vetted design issues with the Tank Supplier can avoid in-Designed maintenance long term issues. Like the below - These issues are avoidable

Monitoring Water Levels:

Maintaining appropriate water levels is essential for the tank's structural stability. Excessive or inadequate water levels can lead to uneven pressure distribution, potentially causing deformation or damage. Install reliable water level monitoring systems and regularly check for proper functionality. Adjust water levels as needed to ensure consistent pressure and prevent unnecessary stress on the tank structure.

Emergency Preparedness:

Develop and regularly update an emergency response plan to address unforeseen circumstances. This plan should include procedures for addressing leaks, overflows, or other critical situations. Ensure that all relevant personnel are familiar with the plan and conduct periodic drills to assess its effectiveness. Having a well-defined response strategy can significantly minimize potential damage and enhance the tank's lifespan.

Professional Inspections:

While regular visual inspections are essential, engaging professionals for in-depth inspections is equally crucial. Schedule professional inspections at least every three to five years, or as recommended by the tank manufacturer. These experts can identify underlying issues that may not be apparent during routine inspections, providing a more comprehensive assessment of the tank's condition.


In conclusion, the lifespan of sectional steel water tanks can be significantly extended through proactive and diligent maintenance. Regular inspections, corrosion prevention, cleaning, ventilation, and structural integrity checks form the foundation of a robust maintenance routine. Monitoring water levels, preparing for emergencies, and engaging professionals for periodic inspections further enhance the tank's longevity. By implementing these comprehensive maintenance tips, individuals and organizations can ensure the sustained performance and reliability of their sectional steel water tanks, ultimately contributing to a reliable and efficient water storage system.

Tank Selection to combat the specific water conditions and external environment is a obvious first start, this where Savanna Tanks with our 35 years Experience can assist, considering we are the only Tank manufacture in Africa offering alternative options
