Clean water is an essential requirement for leading a healthy life. Contaminated water can turn to a wide range of waterborne diseases, making having a clean water storage tank crucial. Efficient cleaning and maintenance of water storage tanks ensure that you have safe and clean water and extend the tank’s life. 

This ultimate guide will explore the water tank cleaning schedule and discuss how often you should clean it.

Frequency of Water Storage Tank Cleaning

Generally, water storage tanks should be cleaned and disinfected at least twice a year. However, the frequency may vary based on factors such as the source water’s quality, the tank’s size, and the level of use.

  1. Water Quality: If the source water is treated and free from contaminants, cleaning may be done once a year. However, if the water is from a well, borehole, or an untreated source, it may require more frequent cleaning, such as every six months.
  1. Tank Size: The smaller the tank, the more frequently it needs to be cleaned. Smaller tanks have less water volume to dilute contaminants, making them more susceptible to contamination.
  1. Level of Use: If your water storage tank serves a large family or commercial establishment, it will require more frequent cleaning as the level of use is higher, leading to a higher accumulation of contaminants.

Signs That Your Water Storage Tank Needs Cleaning

It is essential to watch out for signs that indicate your water storage tank needs cleaning. Some common signs include:

  1. Water Discoloration: If the water coming out of the tap appears cloudy, discoloured, or has a strange smell, it could indicate the presence of contaminants in the tank.
  1. Sediment Build-up: Check for sediment build-up at the bottom of the tank. Over time, sediment and debris can accumulate, providing a breeding ground for bacteria and other microorganisms.
  1. Algae Growth: It is time to clean the tank if you notice algae growth on the tank’s walls or floating on the surface.
  1. Illness: If members of your household frequently fall sick with waterborne diseases, it could be due to contaminated water from a dirty storage tank.

Steps for Cleaning Your Water Storage Tank

Cleaning the water storage tank can be a DIY project, or you can hire professionals to do the job. If you decide to do it yourself, follow these steps:

  1. Drain the Tank: Before you start cleaning, drain the tank completely. This can be done by opening the tank’s drain valve or using a submersible pump.
  1. Remove Sediment and Debris: Use a long-handled brush or a high-pressure hose to remove sediment and debris from the bottom of the tank. Ensure that all corners and crevices are cleaned.
  1. Disinfect the Tank: Fill the tank with chlorine bleach and water. The recommended ratio is 50 ppm (parts per million) of chlorine, which can be achieved by mixing ½ cup of bleach for every 1,000 gallons of water. Let the solution sit in the tank for at least 12 hours.
  1. Scrub the Walls: Use a long-handled brush to scrub the tank’s walls, particularly areas with algae growth or stubborn stains.
  1. Rinse the Tank: Drain the chlorine solution and thoroughly rinse the tank with clean water to remove residual bleach. Refill the tank with clean water, and your tank is ready.
