Water barrel - a practical rainwater tank

Rainwater harvesting is a practical process and an ecological approach to water management. Rainwater harvesting saves potable water and reduces the sewer load. Rainwater collected in this way can be used for various purposes, such as watering the garden, washing the car, cleaning or flushing the toilet. This is particularly advantageous in dry regions, where potable water is more valuable and difficult to obtain. An example of a device that can be installed to store rainwater is a water barrel. In the following article we will introduce the advantages, types and use of modern rainwater tanks.

Why collect rainwater?

Rainwater harvesting has many advantages and valuable uses. Here are some reasons why you should collect rainwater:

• Saving water and money: Rainwater harvesting provides a free source of water for various uses, such as watering the garden, washing the car and flushing the toilet. This reduces the use of mains water, leading to lower water bills.
• Eco-friendly: Rainwater harvesting is an environmentally friendly way to reduce the use of potable water, which is a scarce resource. Rainwater collection helps protect the environment and water resources.
• Watering plants: Rainwater is generally more plant-friendly than tap water, which can contain chemicals such as chlorine. Collecting rainwater and using it to irrigate plants contributes to healthy plant growth and reduces the negative impact of chemicals on the environment.
• Collecting water in times of drought: Rainwater harvesting can accumulate water reserves that can be used during periods of drought or when access to water is limited. This is especially important in areas with an increased risk of drought.
• Reduces the load on the sewer system: Rainwater harvesting helps reduce the load on sewer systems during heavy rains. Rainwater can be used locally instead of being discharged into the sewer system, avoiding blockages and flooding.
• Autonomy and independence: Having your own rainwater source promotes self-sufficiency in water access. Independence from external water suppliers can be especially important in the event of a water supply failure or crisis.

In summary, rainwater harvesting is economically, environmentally and practically beneficial. It helps conserve water, protect the environment, support vegetation, secure water and increase access independence.

How to collect rainwater all year round?

To effectively collect rainwater all year round, there are a number of steps you can take. Below are some suggestions.

Rainwater tank

Install a rainwater tank with sufficient capacity. You can use barrels, cisterns, underground tanks or other systems that can collect more rainwater. It is important that the tank is made of corrosion-resistant material and has a suitable cover to prevent the entry of insects, leaves and other foreign bodies. 

Water collection system

Install a catchment system to allow rainwater to drain into the tank. This can include guttering, downpipes and a filter that will direct water from the roof to the tank.

Water filtration

Rainwater should be filtered to remove impurities before it is collected in tanks. The filter removes leaves, branches, sand and other impurities, making the water in the tank cleaner. 

Antifreeze protection

If you live in an area with cold temperatures and are prone to water freezing, it's a good idea to have an antifreeze system. This could be an antifreeze heater in the tank or proper insulation to keep the water liquid.

Please note that rainwater harvesting may be subject to certain regulations or restrictions, depending on local regulations or property ownership agreements. We recommend that you consult with local authorities before collecting rainwater. 

Types of rainwater tanks

There are many different types of tanks that collect rainwater. Here are some of the most common types of rainwater tanks.

• Rainwater barrel
  A simple and relatively inexpensive rainwater tank made of plastic or metal. Rainwater tanks usually have a capacity of tens to hundreds of liters and can be easily installed under gutters.
• Rainwater cistern
  A cistern is a large rainwater tank that can hold hundreds to thousands of liters of water. Cisterns can be made of various materials, such as concrete, plastic, steel and composites. It can be installed underground or above ground, depending on preference and space availability.
• Underground tank
  Underground rainwater tanks are hidden underground, saving space on the surface. They are often made of concrete or plastic and have a large capacity. Underground tanks are more sophisticated and can be equipped with filtration and pumping systems.
• Modular system
  The modular system is a flexible and scalable solution for building tanks of any shape and capacity. They consist of modules that can be connected together to form tanks of the appropriate size and capacity.
• Roof-mounted tank
  Roof-mounted rainwater tanks are used for flat roofs and roofs with special construction. Water can be collected directly from the roof, eliminating the need for downspouts or other drainage systems.

When choosing a rainwater tank, it is important to consider capacity, available space, materials, budget and specific needs and preferences. It is also important to make sure that the tank is adequately protected from debris, such as leaves and insects, and that the tank is accessible for maintenance and cleaning. 

Rainwater barrel and its types

Rainwater barrels are a popular type of tank with many benefits. Here are some of the different types of barrels:

• Plastic barrel
  The most common rainwater tanks are made of plastic such as polyethylene. Lightweight, durable and corrosion-resistant. They are available in a variety of capacities, usually from tens to hundreds of liters.
• Metal barrel
  Rain barrels made of metal, such as stainless steel or galvanized sheet, are more aesthetically pleasing and can be more durable than plastic barrels. They come in a variety of sizes and shapes.
• Wooden barrel
  Wooden water tanks have a rustic feel and enhance the unique look of the garden. However, to ensure durability and resistance to moisture, the wood must be regularly maintained and treated.
• Decorative barrel
  There are also decorative rain barrels that have an aesthetically pleasing design and can serve as a garden decoration.

The key is to choose a water tank that suits your needs, available space and budget. It is worth paying attention to the quality of the material, the dirt-proof lid, and the filtration and drainage systems, which can be additional features of the barrel, before buying.
