CLEAN WATER: THE WORLD’S NEXT “OIL”?
You may have heard predictions about how the 21st-century may see clean, drinkable water become like crude oil in terms of value, scarcity, and worldwide demand. Whether or not that comes true, there is no question that in today’s world you cannot always rely on the purity of the water flowing from your tap. That’s where water care Systems can help.
Whether your home currently is supplied with municipally-treated water or you get drinkable water from a well or bore on your property, the water originates in one of two places. It is either ground water from an aquifer, a natural underground water supply, or it is surface water from a lake, river, or reservoir.
Unfortunately, you can’t depend on either source to be free of contaminants. Even if you know your water comes from an apparently protected source, like a pristine reservoir, nearby geological features or human activities in the area can lead to contamination. Some natural “contaminants” can actually be beneficial, like the calcium and magnesium found in natural mineral water. Other natural contaminants, like radon, microorganisms, and algae toxins, are not. Most other contaminants are chemicals from human activity that have found their way into the local aquifer or surface water. These are potentially harmful substances such as: lead, mercury, pesticides, VOCs (volatile organic compounds), the gasoline additive MTBE, and a variety of particulates.
DHAKA WASA WATER TREATMENT
Only the beginning
Most cities and towns have some type of water treatment system that filters the public water supply and disinfects it with chemicals such as chlorine or chloramine to make it safe for home use. But while this treatment can destroy harmful microorganisms, sometimes the disinfection process results in new disinfection by-products (DBPs), such as THMs (trihalomethanes), Haloketones, Haloacetylnitriles, and Chloropicrin.
Getting your water tested
Many cities or local health agencies offer water-testing services. It is a good idea to have the tap water in your home tested so that you will know exactly what types of contaminants you may have in it – or just for added peace of mind. (This includes private well/bore water.)
GETTING THERE IS HALF THE BATTLE
Water is usually distributed through city or regional water pipes, where it can also pick up contaminants:
Cracks and faults
If pipes are old, they may have cracks that can allow external contaminants to make their way into your water.
Some pipes materials or the way they are assembled may leach into the water.
It is also possible that cross connections, such as sewage lines that are in close proximity to water lines, may increase the risk of water becoming contaminated.
Storage tanks and rooftops
Water is also vulnerable to contamination in rusty storage and rooftop tanks.
Home pipes or service connections
Depending on how old the pipes are, your water may be a danger of contamination from substances, such as lead, as it travels to your faucets.
