How to effectively manage rainwater?

Rainwater, although of a different quality than tap water (drinking water), can be used in many ways in households and agriculture, as well as in industrial facilities. In most cases, rainwater is successfully used for:

• watering the garden,
• flushing toilets,
• washing clothes,
• filling swimming pools and ponds,
• washing cars and machines,
• various cleaning tasks in the garden.

Proper management of rainwater allows you to save increasingly expensive tap water, which translates into tangible benefits in your home/company budget and in protecting the natural environment. It is possible to reduce the consumption of drinking water by up to 50%! A special installation is necessary for the effective collection and use of rainwater. It consists of several elements, among which the tank plays a key role. The system must also include an efficient pump, which is responsible for distributing water from the tank to individual receivers.

Tank – the basic element of the rainwater management system

It is in the tank that rainwater is stored. Rainwater tanks are available in many variants, adapted to various needs and requirements. There are underground and above-ground rainwater tanks, plastic (polyethylene) and concrete (rarely used these days) to choose from. In addition, the models offered differ in terms of capacity and durability.

Underground Rainwater Tanks – Capacity, Economy and Aesthetics

Underground tanks for storing rainwater, as the name suggests, are installed underground. They have huge capacities – from a few to several thousand liters, which is why they are an excellent choice for very high water demand. An underground tank requires burying, which involves the need to designate an appropriate space for installation and carry out earthworks. On the other hand, an underground installation saves space in the garden, provides a completely discreet effect and prevents water from heating up.

Which underground rainwater tank should I choose?

When choosing an underground tank, you should take into account, among others: • the specifics of the terrain, • individual demand for rainwater, • durability requirements, e.g. for pedestrian and car traffic.
