Raven Tanks Insights: Addressing 7 Common Challenges in Water Storage Tanks

Whether you manage a government office or oversee operations in the energy or mining sector, the installation of a water storage tank is a valuable investment. These tanks alleviate pressure on public water supplies during droughts and offer the opportunity to collect rainwater for various purposes, from watering plants to household use. Despite their benefits, these tanks are susceptible to damages due to constant exposure to the elements, necessitating regular maintenance and repair. 

To help you maintain an appealing property, this article from Raven Tanks highlights common water tank problems and provides insights on how to prevent them. 


  1. Tank Tipping or Setting

Improperly installed storage tanks can tilt or settle unevenly, posing risks due to their weight. Professional installation following manufacturer instructions is crucial, especially for larger tanks that require a stable base. Adequate site preparation, including compacted soil and proper water runoff management, helps prevent damage and ensures longevity. 


  1. Accumulated Sediment in the Storage Tank

Sediment buildup is a common issue in frequently used storage tanks. While installing a filter can help, practical solutions involve periodic draining and rinsing of the tank. Using a pressure washer for cleaning, along with safety precautions, is advisable. Ensuring clean pressurized water before maintenance is essential. 


  1. Leaks around Tank Fittings or Broken Fill Piping

Leaks often occur around tank fittings or pipes connected to fill or discharge ports, particularly when using rigid connectors. To avoid damage, it’s essential to install flexible connectors at all connection points, as they can withstand stress and accommodate slight shifts caused by settling or seismic activities. 


  1. Green or Black Algae Growth in the Storage Tank

Certain tank materials, especially white or transparent plastic, promote algae growth. This issue can lead to water contamination. Using tanks that limit sunlight exposure, either through color or construction, helps prevent algae growth. Avoid long-term solutions involving chemical additives, as they may contaminate the water. 


  1. Bullet Holes in the Storage Tank

Vandalism, such as using arrows or guns, poses a threat to water storage tanks. Employing screening measures and choosing neutral or natural colors can deter such incidents. HDPE plastic tanks can be easily repaired, while steel tanks may require welding or suitable adaptors. 


  1. Fire Damage to the Storage Tank

Fires can cause plastic and metal tanks to melt or warp. Safeguarding the water system involves clearing vegetation around tanks, using fire-resistant piping, and placing gravel or rocks to create a protective barrier. 


  1. Dead Animals in the Storage Tank

Dry seasons may lead animals to seek water sources, resulting in them getting trapped in open storage tanks. Securing tanks with lids and metal mesh prevents such incidents. In case an animal falls in, it can be retrieved with a pool net, and the tank should be chlorinated and flushed before refilling. 



A damaged water storage tank not only impacts the property aesthetically but also affects the water supply.
