Water storage tanks or holding containers are commonly used in commercial and residential buildings. Over a period of time, these tanks get contaminated or clogged with dust, deposits and impurities which settle to the bottom of the tank or forms a layer on the inner surfaces of the water tank. With these accumulations, consumers are forced to use such contaminated water during bathing, washing and also for drinking. Diarrhea occurs world-wide and accounts for 4% of all deaths and 5% of health loss and disability. It is most commonly caused by gastrointestinal infections which kill around 2.2 million people globally each year, mostly children in developing countries. Contaminated water is one of the main causes of diarrhea, Cholera and dysentery, which at times are life threatening conditions.
Safe and easy availability of water is important for public health, whether it is used for drinking, domestic use, food production or other purposes. Improved water supply and sanitation, and better management of water resources, is essential part of a healthy nation. Everyone has the right to sufficient, continuous, safe, physically accessible and affordable water for personal and domestic use.
Contaminated tank water and poor sanitation are linked to transmission of diseases such as cholera, diarrhea, dysentery, hepatitis A, typhoid and polio. Inappropriately managed water and sanitation services expose individuals to preventable health risks.
Inadequate management of urban, industrial and agricultural wastewater means the drinking water of hundreds of millions of people are dangerously contaminated or chemically polluted.
Some 842,000 people are estimated to die each year from diarrhea as a result of unsafe drinking-water, sanitation and hand hygiene. But diarrhea is largely preventable, and the deaths of 361,000 children aged under 5 each year could be avoided each year, if these risk factors were addressed.
Diarrhea is the most widely known disease linked to contaminated water but there are other hazards. Almost 240 million people are affected by schistosomiasis – an acute and chronic disease caused by parasitic worms contracted through exposure to infested water.
In many parts of the world, insects that live or breed in water, carry and transmit diseases such as dengue fever. Some of these insects, known as vectors, breed in clean, rather than dirty water and household drinking-water containers can serve as breeding grounds. The intervention of cleaning water storage containers can reduce vector breeding.
Apart from this major issue, expensive bathroom fittings and sanitary equipments, filters get clogged, due to accumulation of dirt and debris. Hence, there exists a need for frequent cleaning of tanks to remove dirt and debris in the water.
There are two ways to perform a storage tank cleaning. One is by manual method and the other is mechanised .In the former that is manual cleaning, humans are often involved in cleaning the storage container and the inner surface by using a cleaning device for example brush or scrub to remove the dirt and debris. One of the dangerous aspects of the manual cleaning is children below age are often compelled to get down into the tank and this causes injury occasionally and asphyxiation due to plastic ageing. The latter method is by using a pressurized , powered sprays . This method depends on electricity to power the pump or sprayer. These devices are not user friendly and are cumbersome . Though effective when compared to manual cleaning, they end up being more expensive and inconvenient!
The HANBAZ cleaner, enables ease of cleaning of the overhead water tanks in an efficient manner without emptying the tank, though the tank may contain sufficient water. It is light and easy to operate and cleaning can be done at one‘s convenience.
