How regular maintenance would have prevented water tank failures


The storage tank is a critical piece of static equipment in the oil and gas industry for storing fluids. Even though various codes and standards require storage tanks to be designed to avoid failure, there have been numerous incidents of storage tank failure. Thus, storage tank failure is not a novel occurrence. In this article, we will look at the causes of such tank failures as well as preventative measures.

Common Water Tank Problems and How to Fix Them:


    • 1. Accumulation of sand and sediments

This is one of the most common problems with all types of rainwater tanks. A layer of stockpiled solids forms at the bottom and walls of the tank and must be removed on a regular basis…

    • 2. Algae growth

This occurs when the tank’s material does not block the sunlight or when the lid has been lost or removed from the unit. The most reliable way to prevent algae formation is to limit your supply’s exposure to sunlight…

    • 3. Bent or broken pipes

Leaks around tank fittings are as common as bent or broken pipes connecting to the fill or discharge ports. It occurs when piping at the polyester water tank is not connected with a suitable flexible connector…

    • 4. Tank tipping

Take care to direct any water runoff from rains or tank overflow away from the tank base area so that erosion does not undermine the unit’s foundation…

Pro Tip: It is far less expensive to inspect your water tank on a regular basis for potential problems than it is to clean up the mess when it suddenly fails. So, never put off even seemingly minor repairs to a damaged water storage tank.

Other Common Causes of Storage Tank Failures:

    • Corrosion: Most Common cause of storage tank failures
    • Improper Construction
    • Poor Maintenance

Types of Storage Tank Failures:

  • Failures based on Pumping,
  • Based on the Material,
  • Based on service,
  • Mechanical, civil, or electric failure, etc.

You will get many references for storage tank failures over the net caused by corrosion, improper construction, poor maintenance, etc. We will explain a few storage tank failure examples based on Mechanical Failure.

Prevention of Storage Tank Failures:

    • The emergency vent system must protect all tankages.
    • All tankages must be inspected on a regular basis.
    • Contingency reserves should be considered in the design of the firewall and bund wall.
    • Roofs that are self-supporting or have external roof supports
    • Tank thickness must be properly designed.
    • To reduce corrosion, proper metallurgy of the used compatible material is required.
