Two Reasons to Have Your Rain Water Tank Cleaned Regularly
The rain water collected in rain water tanks is routinely used by many homeowners, farmers and owners of industrial facilities for things such as washing clothes, flushing toilets, irrigating farmland and (in industrial settings) operating cooling systems. Here are two reasons why those who make use of this equipment should have it professionally sanitised on a regular basis.
To prevent premature failure of the equipment
Over time, particles of dirt, sharp stones and other debris can get into a rain water tank. Many people mistakenly assume that the presence of dirt and debris in the tank doesn't really matter, as long as the water is not going to be used for personal consumption.
However, this is not the case, as particulates inside the tank can drastically reduce the equipment's lifespan by creating blockages in its filters and by abrading and creating holes inside the pump lines.
Rain water tank cleaning can eliminate these potentially harmful particulates; during this process, the tank is emptied and hosed down with a jet washer, the force of which will push off any tiny stones, dirt particles or other debris that could damage the system.
To maintain sanitary conditions within the tank
If they are not sanitised on a regular basis, rain water tanks can become breeding grounds for numerous types of harmful microscopic pathogens, some of which could pose a risk to human health or the environment.
The reason for this is that rainwater often contains small amounts of viruses, parasites and bacteria. When this water is then stored in a tank which has not been disinfected, these microorganisms will start to breed, as the dirty tank provides the perfect environmental conditions for this activity (that is, it offers a warm, oxygen-rich and moist environment).
This can be a very serious issue if the rain water is then used to irrigate crops or to hydrate farm animals, as these pathogens can then enter the food chain.
Fortunately, regular cleaning can prevent this problem from occurring. A typical rain water tank cleaning service will involve not only the aforementioned jet wash (which will rinse off a substantial amount of the microorganisms that may be clinging to the walls of the tank after it has been emptied) but also a disinfection of the tank itself and its pump system. Chlorine is normally used for the disinfection process, as this chemical can kill almost all dangerous pathogens.
