Retention Tanks

Retention tanks made of HDPE plastic pre-take up rainwater when it is more accumulated. In addition, they protect the investment against flooding by means of a regulated water outflow. The tanks can be optionally equipped with systems for using rainwater for garden watering, flushing toilets, car washes, laundry facilities, etc. The tanks in our range are made using the rotational moulding process or the SPIRO welding method, which guarantees tightness and durability for years.

Retention tanks in general are artificial water reservoirs designed to protect against the effects of heavy rainfall, i.e. flooding of the area. Reservoirs also have additional functions, e.g.: they can serve as a fire reservoir or as an additional water resource for irrigation of green areas. The water collected in the retention tank can also be used for other purposes: washing, toilet flushing, etc.
