What Is A Underground Water Tank?
Sometimes we get too much rain and other times we don’t get enough rain. One good idea is the use of for capturing rain water and storing it for future use, during those times when rain is sparse.
Rainwater tanks are also referred to as rain barrels and in the United Kingdom they call them rain butts. Whatever you call them, their function is to capture rain water that is stored and used when water is scarce. Most of the time above ground tanks are used but sometimes in-ground tanks are installed, particularly in more arid climates when times of drought is all but certain. The most common type is the Plastic Water Tanks
A rain water tank may be made out of plastic, concrete, galvanized steel, stainless steel or fiberglass. Fiberglass and stainless steel are resistant to chemicals and also rust proof. The most common tank is the Plastic Water Tanks. In most cases, they are stored above ground in places like rooftops, patios and at the ends of driveways as well as other surfaces where water cannot penetrate.
Water collected in these receptacles may be used for a number of things. Common uses include watering lawns and gardens, household plumbing like toilets and washing machines, washing the car, agricultural irrigation and even drinking water. If it is to be used for drinking, special care must be taken to ensure that the water does not get contaminated.
First of all, steps can be taken before the water is collected to help keep it safe. Some tanks include things like screen coverings to prevent dirt, debris, bird droppings and insects from getting inside. Selecting an opaque tank is wise to keep sunlight out and thus reducing the risk of algae growth and an overrun of bacteria. A plastic lining is good to prevent leaks and help maintain high water quality.
Even if all these steps are taken to protect the collected water, it is still vital that any water be filtered before it is drunk. Rain water is pure. However, it can become contaminated after collection by outside forces such as air pollution. It is not advisable to drink stored rain water unless there are no other available options.
The use of tanks for rain collection can impact the environment, either positively or negatively. Wide use of these tanks will lessen the amount of water that reaches the ground in certain areas and limit the amount that reaches streams. Depending on where the use of tanks is taking place, this may prevent erosion, sedimentation and pollution. On the other hand, it may cause stagnated ponds and dried up rivers. If the collected rain is used within the same area and put back into the ground, it can actually have the effect of stabilizing ponds and rivers.
