LIST OF UNDERGROUND TANKS (REWATEC)
When choosing the right rainwater tank, it is worth paying attention to the technical parameters of the tanks. Underground tanks are made of durable polyethylene. They have a producer's certificate confirming their durability. Their monolithic structure, without seams, makes them 100% airtight.

The first aspect that is worth paying attention to when choosing a tank is the type of soil on which the tank will be located. When choosing a tank, soil permeability and the presence of groundwater should be taken into account. Some tanks cannot be installed in difficult water and ground conditions. Other tanks may be and others require special precautions to make such an installation possible. Not every tank will work under the given conditions.

The next parameter that should be taken into account is how the land above the tank will be used. That is, whether there will be pedestrian, car or truck traffic over it. It is important because most of the tanks require additional assembly procedures so that cars can pass over the buried tanks. The depth of foundation of the tank under the ground should also be analyzed, because each tank has the maximum ground coverage specified by the producer. Deeper burying of the tank is possible in some cases. However, it is connected with the use of additional security and reinforcements. This increases investment costs.

The table below presents a list of tanks based on parameters such as capacity, possibility of foundation in groundwater, type of soil at the place of installation, maximum ground coverage without additional protection, movement over the tank. In addition, the table contains information about the tank accessories and possible applications for the storage of various types of liquids.

The BlueLine II underground tank is available in four sizes. These are the capacities of 2600 l, 5200 l, 7600 l, 10000 l. It is designed for the storage of rainwater and municipal sewage (septic tank). The design of the tank allows for installation in permeable soils, as well as in groundwater, but up to 1/3 of the tank height. Pedestrian, car and truck traffic may take place over the tank. Additionally, a riser tube and a cover should be fitted to the tank, as they are not its basic equipment. On the basis of this tank, two garden sets for the use of rainwater (STANDARD and PREMIUM) were created. In addition, this tank is available in home and garden sets (ECO, STANDARD, PREMIUM), where rainwater can be used not only for watering the garden, but also for flushing toilets or washing.

The BlackLine underground tank is available in three sizes: 5200 l, 7600 l, 10 000 l. The durable construction allows it to be placed in groundwater up to the height of the ridge. It can be used in permeable and impermeable soils. There may be pedestrian, car and truck traffic above the tank. Additionally, a riser pipe and a cover should be fitted to the tank, as they are not its basic equipment. The tank can store rainwater and municipal sewage (septic tank).

The F-Line underground tank is a flat-structure tank with a capacity range from 1500 l to 7500 l. The advantage of such a structure is the possibility of making the excavation shallower compared to other cylindrical tanks. The tank is adapted for installation in favorable and unfavorable water and ground conditions. It can be located in groundwater. There may be pedestrian and car traffic above the tank. Tanks from 1500 l to 5000 l have a basin for the pump. This allows the maximum use of the water in the tank. On the basis of this tank, two garden sets for the use of rainwater were created: STANDARD and PREMIUM. In addition, this tank is available in home and garden sets (ECO, STANDARD, PREMIUM), where rainwater can be used not only for watering the garden, but also for flushing toilets or washing. Additionally, a riser pipe and a cover should be fitted to the tank, because they are not its basic equipment. The tank can store rainwater and municipal sewage (septic tank).

The Neo underground tank is characterized by a wide range of sizes, from 1500 l to 50 000 l. It is a flat design tank. As a result, the trench intended for its installation is much shallower than in the case of other cylindrical tanks. Its durable structure allows it to be place in permeable and impermeable soils as well as in groundwater up to half of its height. There may be pedestrian, car and truck traffic above the tank. Additionally, a riser pipe and a cover should be fitted to the tank, as they are not its basic equipment. The tank can store rainwater and municipal sewage (septic tank). This tank is the basis of the rainwater utilization system in the garden. It is available in two versions: STANDARD and PREMIUM. In addition, this tank is available in home and garden sets (ECO, STANDARD, PREMIUM), where rainwater can be used not only for watering the garden, but also for flushing toilets or washing.

The Neo X-Line underground tank is available in sizes from 1500 l up to 50 000 l. It is a tank with a flat structure. As a results, the trench intended for its installation is much shallower than in the case of other cylindrical tanks. This tank is a much more durable version of the NEO tank. It allows for its foundation in clay, loam, cohesive and poorly permeable and permeable soils without any special assembly procedures. Additionally, the tank can be completely submerged in groundwater. There may be pedestrian, car and truck traffic above the tank. The riser pipe and the cover must be fitted to the tank, as they are not its basic equipment. The tank can store rainwater and municipal sewage (septic tank). The tank can be the basic element of the rainwater management system in the garden, as well as in the home and garden.
