The underground tank is a device that allows rainwater to be collected for reuse throughout the year. To achieve this, the water is stored in the tank and can be easily reused for all your DIY and gardening activities. The choice of an underground tank should basically be based on three elements: its manufacturing material, its volume, and its type of installation.

The underground tank is a truly ecological solution, both civic and economical. Regarding the type of installation, you can choose between a tank placed on the surface, i.e., above ground, or an underground tank, which is much more discreet and allows you to optimize the space in your yard or home. Indeed, the tank can be installed both indoors and outdoors. As for the construction material, you can choose between a high-density polyethylene (HDPE) underground tank, a flexible tank, or a concrete one. The polyethylene underground tank proves to be the most efficient due to its lightness, resistance, and ease of handling and transport. With the primary advantage of being recyclable, this tank does not cause any corrosion problems in the pipes, as it does not neutralize the natural acidity of rainwater. To properly protect the water from dirt and prevent the formation of algae in the tank, consider equipping it with a lid designed for the irrigation pump and several holes for the suction and discharge pipes.
