Answers:Advantages Cheaper : When it comes to saving money, this one s definitely on the shortlist. After all, rainwater is cheaper than the stuff you pay to have piped in. NB : The installation isn t particularly difficult. Add value to your property : Reducing or eliminating the need to buy water can increase the value of your home. You ll use less water : Like a lot of things, knowing you can is often enough. Once the tank is in place, you may find yourself using a little less water simply because you know it s there, if you need it. Disadvantages-if placed under ground Hard to extract water (need a pump). Difficult to detect leaks and cracks. Expensive (Includes Excavation costs). Can be damaged if heavy vehicles are driven over it. Can be damaged by tree roots. Contamination risk from groundwater. Risk of children, adults and animals Disadvantages-if placed above ground Affected by weather. Take up space. Require anchoring when there is less water in the tank.
Answers:Pro: removes ions, aiding in cleaning with soap and detergent. Con: Unhealthy to drink. Can leech ions off of metal pipes due to water being a universal solvent.
Answers:The advantages are that it kills bacterias and viruses and make the water safe to drink. Chlorination is one of the major reason why we live longer in industrialized countries. The disadvantages are that it smells bad and tastes bad if there is too much.
Answers:The advantages of water chlorination: 1. Controls Disease-Causing Bacteria: Disease-causing bacteria may enter the well during construction, repair, flooding or as a result of improper construction. Proper chlorination will kill these bacteria. 2. Controls Nuisance Organisms: Chlorine treatment will control nuisance organisms such as iron, slime and sulfate-reducing bacteria. Iron bacteria feed on the iron in the water. 3. Mineral Removal: Large amounts of iron can be removed from water by adding chlorine to oxidize the clear soluble iron into the filterable reddish insoluble form. Chlorine helps remove manganese and hydrogen sulfide in the same way. The disadvantages of water chlorination: 1. No Nitrate Removal: Chlorine will not remove nitrates from water. The claims of some water treatment firms imply that nitrates can be removed by chlorination. This is not true. Adding chlorine may prevent nitrates from being reduced to the toxic nitrite form; however, nitrates are not removed from water by chlorination. 2. Causes Smell and Bad Taste: Chlorine in water is not poisonous to humans or animals. However, if the concentration is great enough the water will taste bad so consumption may be reduced. Some people object to the smell and/or taste of very small amounts of chlorine. In those cases an activated carbon or charcoal filter may be used to remove the chlorine from the drinking water. 3. Trihalomethanes (THMs) are organic chemicals that may form when chlorine is used to treat water supplies that contain humic compounds. Humic compounds form as a part of the decomposition of organic materials such as leaves, grass, wood or animal wastes. Because THMs are very seldom associated with groundwater, they are primarily a concern where surface water supplies are used. Lifetime consumption of water supplies with THMs at a level greater than 0.10 milligrams per liter is considered by the Environmental Protection Agency to be a potential cause of cancer. THMs can be removed from drinking water through use of an activated carbon filter.
