How to Clean Water Tank Without Removing Water?

While traditional methods of cleaning a water tank involve draining the entire tank, this can be time-consuming and wasteful, especially in areas with water scarcity. Plus, one of the biggest challenges is finding the right time to empty the tank. However, cleaning your water tank without draining all the water is easier than you might think. And it helps save water while ensuring your tank remains hygienic and safe for daily use.  Whether it is your overhead water tank or underground tank, timely cleaning ensures better water quality for bathing, washing, and even drinking (if used for potable purposes). Below, we explain how to clean water tank without removing water and also share additional home water tank cleaning tips.

Steps to Clean Water Tank Without Removing Water 

At Astral, we recommend the simplest and most effective way to maintain a clean water tank without emptying all the water inside and letting the water go to complete waste. Follow this practical, hassle-free water tank cleaning routine.

Step 1: Lower the Water Level

Before you begin, reduce the water level to around 20-30% of the tank’s capacity. This will give you enough room to clean while avoiding wastage.

Step 2: Use a Water Tank Cleaning Solution

Pour a recommended amount of a safe, non-toxic water tank cleaning solution into the tank. The solution will help loosen all the dirt, algae and sludge stuck to the walls and base of the tank.

Step 3: Scrub the Tank Interiors

Use a long-handled brush or scrubber to scrub the walls, floor and corners of the tank. Focus on areas with visible dirt or slimy layers. This step is important because it helps remove accumulated dirt, ensuring the tank remains clean and hygienic for safe water storage.

Step 4: Let the Cleaning Solution Work

Allow the cleaning solution to settle for 30-45 minutes. This will help break down grime and allow debris to settle at the bottom.

Step 5: Remove Sludge and Debris

Use a bucket, scoop or a small submersible pump to remove the settled dirt and sludge. A wet vacuum, if available, also works well.

Step 6: Do a Quick Rinse with Clean Water

Quickly rinse the tank with clean water to remove any remaining dirt or cleaning solution.

Repeat this home water tank cleaning process every 4-6 months. It ensures cleaner water, prevents bacterial growth and maintains the overall hygiene of your tank without wasting large amounts of water.

How to Buy a Suitable Home Water Tank That is Easy to Clean?

If you are planning to buy a water tank for your home that can be kept clean with minimum maintenance, here’s what to consider:

Step 1: Pick Water Tanks Made of Quality Material

Always opt for tanks made from food-grade, UV-stabilised plastic or high-quality polyethylene. These materials prevent algae growth and protect your clean water from contamination. Astral Pipes manufactures water tanks using only high-grade, food-safe polyethylene. 

Step 2: Ask About Water Tank’s Warranty

Select a reliable brand known for quality and durability. Tanks with good warranty coverage ensure peace of mind and long-term use. Astral water tanks typically come with a 10-year warranty against manufacturing defects, valid from the date of purchase.

Step 3: Check if Tank’s Capacity Meets Daily Water Needs

Choose the tank size based on your family’s daily water consumption. For small families, a 500-1000-litre tank works well, while larger households may need 1500 litres or more. At Astral Pipes, you will find a range of water tanks available in capacities ranging from 500 litres to 5000 litres, meant for residential and commercial use. 

Step 4: Look for Multi-Layered Tanks with Smart Design

Multi-layered tanks offer better protection against sunlight and heat, keeping the stored water cooler and cleaner. A smooth inner surface also makes home water tank cleaning easier. Our range offers blow-mould water tanks and tanks with 2 to 4 layers, which are designed to block harmful UV rays and minimise heat absorption, helping maintain water quality and safety.

Step 5: Choose Tanks Designed for Easy Cleaning

Select tanks that are designed with cleaning convenience in mind. Models featuring larger lids or manholes make it easier to access the interior during cleaning, reducing effort and improving hygiene. A wide opening allows you to scrub corners effectively, remove sludge and carry out routine maintenance without hassle. Astral water tanks are designed for easy cleaning access, and this has helped maintain water quality over the years.Explore our range of plastic water tanks at Astral Pipes to find the right tank that meets your water storage needs.
