Plastic Water Tank Cleaning Service: Get Your Water Stored Cleaner

Plastic water tanks are widely used in homes, apartments, villas, offices, schools, hotels, clinics, shops, and commercial buildings. While being light, they are still solid and used in everyday water storage.

Nevertheless, every water tank, including plastic ones, requires periodic cleaning and maintenance.

A plastic water tank may accumulate sludge, sediments, algae, dust, rust, insects, and various other unwanted substances.

Even if the supplied water seems clean, over time, it may still contribute to the overall dirt inside the tank.

Hence, the plastic water tank cleaning service plays a vital role in keeping the stored water clean and healthy.

It can effectively remove dirt from the walls and the floor, take away sludge from the bottom, get rid of algae, and help maintain a clean storage area.

Moreover, in case your property also uses concrete water tanks, you may want to additionally consider the Affordable RCC Water Tank Cleaning service.

In this article, we present a comprehensive guide about plastic tank cleaning, including the basics, services, symptoms, and guidelines for choosing the best plastic tank cleaning service.

What Is a Plastic Water Tank Cleaning Service?

A plastic water tank cleaning service is a professional maintenance procedure for plastic water tanks used in homes, offices, and commercial buildings.

These storage systems are typically installed on rooftops, terraces, utility areas, and commercial premises.

Plastic water tanks may also be known as overhead plastic tanks, sintex-type water tanks, rooftop water tanks, residential plastic tanks, and commercial plastic tanks.

A plastic tank cleaning service usually consists of a thorough washing procedure to remove dirt, sludge, algae, and other unwanted materials from the tank walls, floor, and corners.

The process may also include vacuum cleaning, sludge removal, inspection, sanitization, and final rinse, depending on the tank size and its overall condition.

Why Do Plastic Water Tanks Become Dirty?

Even though a plastic water tank may look clean from the outside, the interior surface can accumulate various undesirable deposits over time.

Sediments from the supplied water can also build up on the tank bottom, especially if the tank is not properly maintained.

Algae can develop if the tank is exposed to sunlight.

Furthermore, dust and dirt can get into the tank through the opening, especially if the lid is broken or improperly closed.

Rust from the pipeline and various other foreign objects, including insects, can also make their way into the tank.

Moreover, the longer the tank remains uncleansed, the more dirt can accumulate inside.

Common Signs Your Plastic Water Tank Needs Cleaning

Below are the most common symptoms that indicate a plastic water tank may require cleaning.

1. Cloudy Water

If the water retrieved from the tank appears cloudy, it can signify that the tank interior has dirt that mixes with it.

2. Bad Smell

A foul odor can be a result of poor maintenance and dirty water stored in the tank.

3. Sludge at the Tank Bottom

The presence of a thick layer of mud at the tank bottom is a clear sign of contamination.

4. Green or Dark Stains

The appearance of green or dark spots indicates the presence of algae.

5. Bad Taste

If the water from the tank has a bad taste, it may be contaminated.

6. Visible Stains

If you can see some dirty spots on the tank interior, it may be time for a cleaning.

7. Long Time Since the Last Cleaning

Even if none of the above concerns apply, there is still a chance the tank has not been serviced in a while.

Why Professional Plastic Water Tank Cleaning Is Better

While some homeowners may attempt to clean the plastic water tank themselves, a professional cleaning service can deliver significantly better results.

Moreover, a professional cleaner can remove more stubborn deposits and dirt from the tank walls and the bottom.

A thorough cleaning service can also effectively eliminate heavy sludge and algae that may be present in the tank.

Furthermore, if the tank has not been serviced for an extended period, a professional cleaner can address hard-to-reach spots.

Finally, a professional cleaner can also use a variety of wet vacuum equipment, pressure washers, scrubbers, and other tools to get the best results.

Finally, a professional cleaning service can save you both time and money in the long run.

Professional Plastic Water Tank Cleaning Process

A professional cleaning service typically follows a well-defined plastic water tank cleaning process.

Below are the most common steps involved.

Step 1: Inspection

A professional cleaner will typically start by inspecting the tank to determine its current condition and establish the most appropriate course of action.

The following factors are typically taken into account:

  • The tank’s capacity
  • The tank’s overall condition
  • The amount of sludge present
  • The presence of algae
  • The tank’s accessibility
  • The condition of the tank lid
  • Water quality
  • The presence of other deposits

This information can then be used to develop a suitable cleaning procedure.

Step 2: Drainage of Water

The stored water in the tank is then drained to give better access to the tank floor and walls.

Step 3: Removing Sludge and Sediments

The next step involves the removal of sludge and other deposits from the tank bottom.

This process typically includes the elimination of mud, sand, dirt, and rust.

This step is necessary since simply draining the tank is typically not sufficient to remove thick layers of sludge.

Step 4: Washing the Walls

The walls are then washed to eliminate any algae, dirt, or stains.

The corners and the waterline area typically require special attention.

Step 5: Cleaning the Floor

The tank floor is then treated to remove any remaining dirt or deposits.

Step 6: Pressure Washing

If applicable, the tank can be pressure washed to remove stubborn deposits.

This step may be skipped if the tank is in good condition.

Step 7: Vacuum Cleaning

A vacuum cleaner can then be used to eliminate excess water and dirt.

Step 8: Sanitization

The interior of the tank can then be sanitized to kill any bacteria or mold.

Step 9: Final Rinse and Inspection

Finally, the tank is rinsed and inspected to ensure the best possible results.

Plastic Water Tank Cleaning for Homes

Plastic water tanks are a popular storage solution for residential properties.

The water in them is typically used for a variety of domestic purposes, including bathing, washing, cleaning, and cooking.

As such, it is vitally important to ensure that the residential water tank is properly maintained and serviced on a regular basis.

A professional plastic water tank cleaning service can effectively eliminate sludge and algae from the tank.

Plastic Water Tank Cleaning for Apartments

Plastic water tanks are often used in apartment buildings.

Since these buildings typically have a high number of residents, the tanks may need to be cleaned more frequently.

Moreover, if your apartment has multiple plastic tanks, a professional cleaning service can handle all of them in one go.

In addition, a professional cleaner can help the apartment owners develop a more systematic approach to tank maintenance.

Plastic Tank Cleaning for Housing Societies

Housing societies typically have a variety of water storage solutions, including plastic water tanks, RCC water tanks, underground water tanks, and overhead water tanks.

A professional cleaner can help maintain all of them in good condition.

In addition, if your housing society has multiple water tanks, a professional cleaning service can offer more affordable solutions, such as an Annual Maintenance Contract (AMC).

Plastic Water Tank Cleaning for Offices

Many offices utilize plastic water tanks to store water for the washrooms and cleaning purposes.

In addition, some companies have a pantry area that is also served by a plastic water tank.

A professional cleaning service can help keep these tanks in good condition and prevent excessive sediment build-up.

Sintex-Type Water Tank Cleaning

Sintex-type water tanks are one of the most common plastic water tank types in India.

They tend to feature a variety of interior deposits, including sludge, algae, dust, and sediment.

A professional cleaning service can help remove them more efficiently.

Overhead Plastic Water Tank Cleaning

Plastic overhead water tanks are typically located on the rooftop or terrace of a building.

Due to their location, such tanks are often exposed to dust, pollution, heat, and sunlight.

These factors can contribute to the accumulation of dirt in the tank.

A loose lid or a broken cover can make the tank even more susceptible to contamination.

A professional cleaner can help ensure the tank is properly maintained.

Algae Removal From Plastic Water Tanks

Algae is one of the most common deposits that can be found in rooftop plastic water tanks.

It often presents itself in the form of green stains or dark patches on the tank interior.

The presence of algae can indicate that the tank has not been properly maintained or serviced in a while.

The tank can also be smelled out for unusual odors.

Algae tends to thrive in warm and sunny environments.

It can often be found on the tank walls, presenting itself as green, slippery spots.

It can also be found in the water itself, making it appear greenish.

Draining the tank is typically not enough to remove algae, as it often sticks to the tank interior.

A professional cleaning service can effectively eliminate it with a combination of scrubbing, rinsing, and vacuuming.

Sludge Removal From Plastic Water Tank

One of the most common occurrences in plastic water tanks is the formation of sludge.

It can be the result of sediment build-up on the tank bottom.

The consistency of such a deposit can vary, from thin and liquid to thick and muddy, depending on the tank’s content and how long it has been left without cleaning.

Such a substance can be particularly harmful, as it can often contain various bacteria and other impurities.

In addition, it can be relatively challenging to remove, especially if it has a thick and mushy consistency.

A professional cleaner can eliminate it with the help of appropriate wet vacuum equipment.

Plastic Water Tank Cleaning Cost

When considering a plastic water tank cleaning service, it is natural to be concerned with the cost.

The final price can vary greatly depending on a variety of criteria, including the tank’s capacity, the number of tanks, their overall condition, and the availability of equipment.

Larger tanks, as well as tanks with heavy deposits, will typically incur higher prices.

In addition, a professional cleaning service may charge more for inaccessible tanks or those that required special maintenance.

If you have multiple tanks that need cleaning, it is best to provide the cleaning service with the list of tanks and their approximate capacity.

Affordable Plastic Water Tank Cleaning

While choosing an affordable plastic water tank cleaning service is understandable, it is important to ensure that the selected company actually provides all the necessary services.

Make sure to request a detailed description of the included services.

An affordable cleaning service should not compromise on the quality of maintenance.

Such a service should ideally include sludge removal, wall cleaning, floor cleaning, algae removal, vacuuming, and sanitization.

Affordable RCC Water Tank Cleaning

Many residential and commercial properties have both plastic and RCC water tanks.

For instance, a residential society may have an underground RCC water tank and several rooftop plastic water tanks.

An Affordable RCC Water Tank Cleaning service can be combined with plastic tank cleaning to provide more comprehensive maintenance.

A professional cleaner will typically remove sludge, scrub the tank, and sanitize it.

Since RCC tanks typically have a rougher surface than plastic tanks, a professional cleaning service might use more aggressive equipment to ensure the best results.

Plastic Tank Cleaning vs RCC Tank Cleaning

Plastic and RCC water tanks typically have very different surfaces.

While plastic tanks can be smooth, an RCC tank’s surface can be rough.

Both can benefit from a professional cleaning service.

Depending on the material of the chosen tank, a professional cleaner will prepare a maintenance program that takes into account the specific needs of the selected surface.

How Often Should Plastic Water Tanks Be Cleaned?

There is no universal answer to this question, as the frequency of cleaning can vary drastically from one property to another.

As a general guideline, a water tank should be serviced at least once per year.

The actual frequency can depend on a variety of factors, including the quality of the supplied water, the tank’s location, the amount of sediment, and the number of users.

A tank that is used frequently and/or with hard water typically requires more frequent cleanings.

It can also be helpful to periodically inspect the tank to see if there are any signs of deposits or algae.

How to Keep a Plastic Water Tank Cleaner For Longer

Keeping a plastic water tank clean is a continuous process.

Below are a few simple yet effective measures that can help minimize contamination.

  • Make sure the tank lid is properly closed
  • Avoid exposing the tank to direct sunlight
