Preventive Maintenance Guide for Water Tanks

14 August 2020

Numerous industries utilise water tanks for transporting water supply and any other liquid to their filling stations or sites. The overall construction and build of water tanks hugely depend on the type of liquid they will be transporting as well as the requirements and needs of the customers. Most of the time, these tanks would be built from aluminium, carbon steel, stainless steel, and fibreglass-reinforced plastic, which can all easily handle transport and storage of water and other liquid for a reasonable amount of time.

Water tanks are used every day. Without any preventive maintenance, they can suddenly malfunction and become unusable, which can be costly and damaging to daily operations. To avoid compromising the quality of your water tanks, they must be maintained regularly. Here are some helpful tips that you can do to conduct regular preventive maintenance.

Conduct Visual Inspections

One of the best ways to perform preventive maintenance for water tanks is to check it visually. You may want to inspect the outer shell and other components of the tank for any signs of damages or aging. Dents, scratches, cracks, flat spots, or gouges may also be checked if they somehow exist on the tank. Signs of damage or tampering on the pump-out port or cap and tank straps must also be assessed.

Inspect Plumbing Components

Plumbing components like valves, pressure gauge, and pipes, which are all attached to the tank, must be inspected since they help in maintaining a stable flow, input and output, and storage of the water. Damages, leakage, and accumulation of elements that these components may manifest must also be repaired right away. Their inspection and maintenance allow your water tank to prevent serious damages brought by corrosion, extreme temperatures, excessive movement, aging, and other similar concerns.

Drain and Clean Water Tank

Another tip that you can do for preventive maintenance of water tanks is to regularly drain the water of the tank. To initiate the draining of all water, you must open its outlet valve or tap so that the remaining water will be released from the tank.

Once the water from the tank is drained completely, you may now clean its internal surface. You can use a stiff brush that is attached to a pole or a high-pressure jet to clean the interiors of the tank. Every corner must be reached and scrubbed completely to effectively remove dirt and scale build-up.

In disinfecting your tank, you can utilise the process of chlorination. Chlorination involves the use of chlorine that can be delivered through high-strength calcium hypochlorite. This element can be combined with water for the tank to be disinfected and will be free from any microbes.

Perform Operational Tests

Operational tests are important during preventive maintenance since they gauge the condition of the water tanks. From storing water supply to releasing it to the site, your water tanks must fulfill their functions without encountering problems and issues. Tests and inspections that are related to water tanks would depend on their size and usage. However, these operation assessments must be done monthly, quarterly, or yearly. Going beyond one year without any tests might cost your water tanks to deteriorate and get damaged in the long run. If there are components that have failed during operational tests, then they might need to be fixed or replaced.

Following these tips can help you prolong the service life of your water tanks. These guidelines can also help you assess the condition of your water tanks, find any hidden issues, and resolve them right away.
