Water is the most vital substance for human, animal and plant life. It is also the most daily used resource as it’s used for drinking, cooking, cleaning, and in manufacturing plants and laboratories. It goes without saying that the cleanliness, safety and quality of the water we use is paramount for sustaining the health of the planet and its inhabitants.
Most of the water we use is stored in tanks. These tanks are made from a variety of materials including steel, plastic, fiberglass and concrete, which are all prone to different development of growths and bacteria that harm the water. The main types of water tanks used are overhead tanks, which are placed at an elevated level, e.g. rooftop of a house;underground tanks, which are installed underground and are ideal for uses such as rainwater harvesting, irrigation systems and water storage for firefighters; and ground-level tanks which are placed on the ground.
Dubai residents rely on a tank and pump system for their water, and the Dubai Municipality recommends that all water tanks be cleaned twice a year. This is because cleaning water tanks reduces the risk of water contamination. Stagnant or low circulating water is a conducive environment for all kinds of bacterial growth. Materials like algae and sludge can form on the walls of the tank making the water susceptible to contamination. Dirt, mould and silt deposits can accumulate at the bottom of the tank making the water unfit for consumption and daily use. The bacteria growing inside water tanks produce chemicals and gases that change the water color and give it a bad odor. In many cases, organic matter such as leaves, insects, and small animals find their way into tanks and pollute the water. It’s common to find a dead rodent or decomposing plant materials in water tanks.Taking care of water tanks by cleaning, disinfecting and inspecting them regularly keeps the water supply clean, fresh and safe.
Cleaning water tanks prevents disease outbreak. According to the World Health Organisation, more than 3.4 million people die as a result of water-borne diseases every year, mainly from using contaminated water within their households.Contaminated water is responsible for major outbreaks of severe gastrointestinal illnesses such as gastroenteritis and infections caused by the protozoan parasites Cryptosporidiumand Giardia. Water tanks, if not cleaned,can be potential breeding grounds for harmful, disease-carrying bacteria which expose consumers to diseases such as cholera, diarrhoea, dysentery, hepatitis A, typhoid, polio, Influenza, Legionnaire’s disease, Pontiac fever and other life threatening diseases. Periodic cleaning and sanitation of water tanks ensures cleaner, safer water which saves the consumer from these health risks.
It’s also necessary to clean water tanks because water filters do not guarantee water cleanliness. While the water filtration systems installed in tanks do well to filter out certain kinds of impurities, they may not filter out the germs and bacteria in the water. Filters may filter out dirt particles from a dirty tank but not the harmful chemicals and minerals in it.To enable a better filtration system and to guarantee cleaner water, the tanks must be cleaned from inside. When the main water tank is clean the filtration system can filter the water thoroughly.
Besides, dirty water tanks contribute to clogging and blockages of filters and pipeline systems. Thick pollutants like sludge and algae can get trapped in the filters and pipes and inhibit the flow of the water, cause pressure imbalance and promote leakages and pumping constraints. Moreover,maintenance costs arising from damaged pumps, filters and tanks due to uncleanliness are significantly higher than the cost of periodic tank cleaning. A dirty tank can accelerate the development of rust and corrosion, thereby weakening the tank and making it prone to breakage and cracking, shortening its shelf life.Cleaning water tanks not only prolongs their lifespans but also prevents heavy tank replacement and re installation costs. Apart from saving resources like effort, time and money, regular tank cleaning provides an opportunity to identify any problems in the tank, water and piping systems early enough and have them fixed before they pose a bigger problem. This ensures that the integrity of the water tank is upheld and is always functioning at optimum levels.
Water tanks serve a very important role as safe water reservoirs for everyday use, including in industrial and commercial environments. Keeping water tanks clean and in proper condition at all times is not only required by law, but also an essential health and safety practice.
