Considerations for Selecting Water Tanks
Whether you’re considering water harvesting in the city or needing water storage for your business, there are a variety of water tanks to choose from. Not only are they available in several sizes, but they are made from several materials as well. These considerations will help you select the best water tank for your needs.
The weather can be harsh, so the one consideration for choosing the right water tank is its capability of surviving hot summers, strong storms, and, sometimes, cold winters. Water tanks in Victoria are made from steel, concrete, fiberglass, or polyethylene, which is plastic. Along with surviving exposure to the elements, the amount of water you plan on storing is the main factor in selecting the material.
A water tank needs to be sturdy, remain sealed, and not allow water to leak. A leaky tank will undermine storing water to use in your home, to water livestock, to irrigate crops, or to put out fires. Fiberglass and polyethylene tanks are lightweight and come in several sizes, but they are usually made for storing water for home use.
Concrete and steel water tanks are much stronger, but once they are installed, they are there to stay. They are generally for agricultural or commercial uses, and concrete tanks are often buried underground. These tanks hold much more water, with steel tanks capable of holding anywhere from 30,000 litres to several million litres.
Sizing Water Tanks
To choose the best size for your needs, you can calculate the rain harvesting capacity of a tank. This involves figuring out how much water the catchment area can produce and multiplying it by the amount of rainfall for the area. Since rainfall amounts vary each year, it is better to be conservative in your calculations when selecting the size of the water tank.
It also helps to know how much water is needed every day to serve the needs of everyone in your household, including livestock if you’re using the water for them as well. Most people use about 250 litres per day for bathing, brushing teeth, using the toilet, drinking, and other purposes. Along with use per person, you should also account for appliances that use water, such as a washing machine and dishwasher.
Although some people may consider the colour the least of their concerns, it can be an issue depending on the material the water tank is made from. A fibreglass or polyethylene tank can allow more light in, which can lead to algae growth. If you do use a fibreglass or plastic tank, then you should choose tanks in darker colours.
Since most concrete tanks are underground, the colour isn’t really important, and you can choose any colour you wish when purchasing a steel tank. If it’s a commercial tank, then a colour closely matching one your business uses could be useful. A water tank salesperson can help you select the best tank for your needs, whether it’s for a business or your home.
