Water tank cleaning process goes hitech

Water tank

Hyderabad: When was the last time you got the overhead water tank or underground tank cleaned in your house or apartment? Probably, it is tough to remember.

A peep into the tank and most of the times, you will see moss covered green walls and muddy water at the bottom. It may be hard to believe that the water stored in such conditions is what you consume or use for domestic needs.

Most people tend to ignore the need to get their water tanks cleaned regularly. Though a few individual house owners have the practice of getting the tanks cleaned regularly, for those living in apartments, particularly high-rise structures, it can be a task, not to mention commercial structures. While a secretary or the office-bearers of the association in a residential apartment can keep track of the water tank cleaning intervals, it is hardly followed by any individual in a commercial structure.

This monsoon season, when the probability of vector-borne diseases is high, it is imperative for house owners and even commercial structures owners to get the water tanks cleaned.

Earlier, the tanks were cleaned manually by hiring a couple of daily wage workers and using bleaching powder. But that does not suffice. This apart, most daily wage workers nowadays are reluctant to take up such works or demand exorbitant charges.

Catering to the needs of building owners, especially apartments, many organisations are now offering mechanised water tank cleaning services in the city. Using dewatering pumps, germicidal UV lamps, scrubbers, pressure jets, mud or slurry pumps and water vacuum cleaners, these organisations are taking up water tank cleaning in a sophisticated manner. Each organisation has its own way of cleaning tanks and use different equipment for the purpose.

To begin with, all the water stored in the tanks is drained out and the accumulated mud or sludge is cleared using high-powered water vacuum cleaners. This is followed with applying of anti-bacteria chemicals on the side-walls and floors. After about 30 minutes, the walls and the floor are cleaned using power jet machines. This will help in clearing the moss, minute insects and any other waste in the tank, explains T Sandeep of Kamakshi Water Tanks Cleaning services, Kukatpally (97005-44849).

Once all the water is drained out through pumps, vipers or scrubbers are used to clean the sidewalls and floors to clear the muddy layer on the surface. This entire exercise takes about three to four hours depending on the tank size, he says.

Most people consider cleaning the water tank is only to ensure safe and potable water but there is also another purpose. Usually, water pipes get choked or rusted due to accumulation of trash or mud from the tanks. And to replace such pipes, a lot of effort has to be put in, besides investment of time and money.

Generally, the water tank, which is filled with borewell water, should be cleaned once in three months. If the tanks are filled with water supplied through tankers, then it has to be cleaned once in two months. This is mainly because there is a probability of dirty water or rust from the tankers being released into the tanks, he adds.

These organisations claim use of anti-bacteria chemicals to clean the tank will not have any harmful effects as they are washed away. Depending on the water tank size, these organisations charge about Rs 550 for cleaning a 1000-litre capacity tank and about Rs 1,850 for 5000-litre capacity tank. If a couple or more apartments or individual houses are willing to get the tanks cleaned, then these organisations offer some discounts as well.
