We have all experienced the phenomenon of too much rain at once and then periods of not enough rain. One way to combat those dry periods is with the use of Rain Water Tanks Adelaide to collect the rain water and keep it stored for use at a later time. In the UK, these tanks are called water butts and in North America they are also referred to as rain barrels. Whatever you choose to call them, they are great for catching water that can be used later. Most of these tanks are above ground but in-ground ones can also be used, especially in typically arid climates when dry conditions are a given and water will be in short supply.
Types of tanks may be concrete, plastic or galvanized steel as well as stainless steel and fiberglass which are chemical resistant and rust proof. They are found often on the tops of roofs as well as patios, driveways and other areas with waterproof surfaces. The uses of the collected water vary. Most commonly it is used to irrigate crops. It is also used for everyday household activities like washing the car, flushing the toilet, using the washing machine and watering small gardens and lawns. It may also be used as drinking water. If so, extra attention must be given to the water and the tanks to be certain the water is safe for consumption.
A well equipped tank will make it easier to have a drinkable, uncontaminated water supply. Dirt and debris as well as insects and bird droppings can be kept out with a screen cover. A tank that is opaque will disallow the penetration of sunlight and thus minimize algae and bacteria growth. A plastic lining inside the tank aids in leak prevention and keeps water quality higher. It is also imperative that, even if these steps are taken, any water that is drunk is properly filtered. Even thought rain water is pure, it may become contaminated after collection. And while rain does not contain chlorine, air pollutants can affect the water after it is gathered. It is advised not to drink water from rainwater tanks unless there are no other sources of drinkable water.
How do these tanks affect the environment? Well, obviously any water that is collected in a tank is water that will not reach the ground. If there is widespread use of tanks in a certain area, it can impact the amount of water that runs off into rivers and streams. It could cause stagnant ponds and dry riverbeds. However, it can also help prevent sedimentation and erosion as well as pollution. If the water that is collected is put back into the same area, it could very well stabilize the flow of rivers and the quality of pond water.
