An above-ground tank is used when we want to easily store rainwater from the roof without disturbing the garden with earthworks. The undoubted advantage of this type of tank is its simple installation and the ability to relocate it later. The disadvantage, however, is the space it takes up and the potential to "unsightly" the yard. Some roof structures also limit the collection of water from a single section of the roof (gutter downpipe). Furthermore, above-ground tanks cannot collect water from, for example, perimeter drainage around the house. An underground tank is useful wherever space is limited or the tank itself is not visible. The tank allows for the collection of water from virtually the entire property, whether from the roof or perimeter drainage.

Choosing a rainwater tank is a complex matter. First, you need to know how much water you want available during the summer season. This can be easily determined if you've previously used the mains water supply to water your garden. Then, simply check your bill, calculate the amount, and average it. However, it's important to remember that in the current climate, we're more likely to experience heavy downpours followed by dry periods, so it's better to buy a larger tank than risk a water shortage. Some people choose a tank based on calculating the plot area and/or calculating the catchment area, where the catchment area refers to the area of ​​the plot from which the water will flow into the tank. This is a very professional approach, but it doesn't take into account the previously mentioned uneven rainfall patterns.

Theoretically, rainwater tanks don't need to be cleaned, thanks to filter baskets installed at the inlets. However, tanks are also available without these baskets, so if a filter isn't installed upstream of the tank, all contaminants will end up in the tank. Cleaning the tank is quite difficult due to the small diameter of the inspection hatch.

A domestic sewage treatment plant should be located in a location that allows wastewater discharged from the building to travel the shortest possible distance. This prevents it from cooling, and at higher temperatures, decomposition is more intense. A flow-through underground settling tank designed for preliminary sewage treatment, part of a domestic treatment plant, can be located near a single-family home, provided it is properly vented through a sewer system installed at least 0.6 m above the top of windows and exterior doors. If this requirement is not met, the settling tank must be at least 5 m from the building. If the pipe leading from the building to the settling tank is longer, it should be insulated. When selecting a location for the settling tank, remember that it must be at least 15 m from the nearest well and at least 2 m from the property line and road. A safe distance of 1.5 m from gas and water pipes and 0.8 m from electrical cables should also be maintained.

In good ground conditions, a single-chamber ecological treatment plant will provide drainage for approximately 10 years. A two- or three-chamber ecological treatment plant will provide drainage for approximately 20 years. A good biological treatment plant will provide drainage for approximately 100 years.

Domestic sewage treatment plants usually require emptying excess sludge once a year.

It is possible to convert a concrete septic tank into a sewage treatment plant, provided that the tank is tight and certified.

Ecological treatment plants consist of one of three anaerobic treatment chambers. Through a special installation, wastewater flows into the first chamber. There, substances heavier than water settle to the bottom under the influence of gravity, while lighter substances float to the surface. These phenomena are called sedimentation and flotation. The first chamber has an opening at the appropriate height for the pre-clarified liquid to flow into and into the second chamber. The same processes occur there as in the first chamber, resulting in improved purification. Once the wastewater has been mechanically treated, it flows through a special filter, which further removes residual contaminants. The pre-treated water is then transported to a percolation drain, which distributes the liquid into the ground. There, the remaining organic substances gradually decompose into inorganic compounds. These compounds, however, are in no way harmful to the environment. The remaining, purified water flows into nearby groundwater.

An ecological treatment plant, also known as an ecological septic tank or a drainage treatment plant, is anaerobic treatment in the tank, while aerobic treatment occurs in the drain. This means that the treated water cannot be recovered. Permeable soil (sand, gravel) is essential for installing this type of treatment plant. A biological treatment plant is a multi-chamber tank with an aerated activated bed. This allows both aerobic and anaerobic treatment to occur within the tank. In this type of solution, the treated water can be reused, for example, for garden irrigation. A percolation drain is not necessary. Treated wastewater can also be discharged into a drainage well or a watercourse.

The primary difference between a drainage treatment plant and a tunnel treatment plant is the surface area of ​​the infiltration system. A drainage treatment plant is more affordable for large areas, while a tunnel model is a better choice for smaller plots.

It is assumed to correspond to the amount of water consumed. According to design guidelines, the demand for homes with full sanitary facilities is approximately 150 liters per day per resident, meaning that in the case of a sewage treatment plant for four people, this would be 600 liters. The size of a treatment plant is sometimes also defined by the number of people it can serve. This is known as the population equivalent. The capacity of a domestic treatment plant for four people should be at least 2,000 liters.

The frequency of bacterial replenishment depends on the biopreparation manufacturer, but on average every four weeks.

Double-walled tanks are constructed with two shells, or protective walls, ensuring reliability. If the liquid stored in the first chamber leaks, it will not escape into the environment but will accumulate in the space between the two shells. A single-walled tank lacks this protection and, if damaged, will cause the substance to leak.

Tanks up to and including 2,500 liters are not subject to inspections or audits (they are subject to a simplified form of supervision), while tanks over 2,500 liters are subject to an external inspection every two years. A decision authorizing operation is not issued for equipment subject to simplified technical supervision.

The distribution system consists of: - a suction line terminated with a non-return valve - a filter separator (optional) - a pump with a bypass - a reinforced hose - an automatic gun with a swivel joint.

Rainwater tanks should be properly insulated or emptied in the winter, especially if they're above ground. Underground tanks are less susceptible to low temperatures.

Double-shell tanks provide additional protection against leaks, which increases safety and minimizes the risk of soil contamination in the event of damage to the inner lining.

It is best to entrust the installation of a sewage treatment plant to specialists to ensure that all legal and technical requirements are met and that the system operates correctly.

Yes, rainwater tanks should be cleaned regularly, and filters and rainwater collection systems must be checked periodically for contamination.

Loading
The mold is opened and a weighed amount of polymer is poured into it. This powder can be pre-composed in terms of color, or you can dry mix the coloring pigment before loading the mold.

Heating
The mold is usually closed with quick-release clamps. This is followed by the activation of two-axis rotation on two perpendicular axes in a heated environment. Since the rotational speed is relatively low (below 20 rpm), the powder rotates inside and is heated during this time by convection, conduction and in some cases, radiation. Finally, the powder melts and covers the inner walls of the mold with an even mass, provided the correct rotation speed.

Cooling
Once the molten mass has thickened sufficiently, the mold is cooled until the polymer has reached the right rigidity to achieve the desired shape. This is done with water or water or air or a combination of the two.

Discharge
When the polymer has cooled enough to maintain its shape and to be able to be further processed, the mold is opened and the product is removed. Then the powder is loaded inside again and the cycle starts from the beginning.

Yes, because its longevity depends on it. Incorrect drainage dimensions can cause silting of the layers beneath the distribution pipes. Properly cut and installed pipes, as well as the correct ratio of drain length to sewage volume (dependent on the PE), guarantee the proper operation of the system.

Detailed foundation guidelines are delivered to the customer with each piece of the ordered tank. The supplied tanks, like all large plastic objects, are intended to be installed in non-irrigated soils – deprived of groundwater in impassable areas. It is allowed to lay tanks
in irrigated soils, with the use of foundation conditions according to the structural design and in a passable area with the use of appropriate toppings. The foundation of the tanks includes:

excavation,
making sprinkles,
installation of the tank and backfilling with backfill,
protection of the reservoir in irrigated ground and passable area.
Our tanks are perfect as rainwater retention tanks. Water managed in this way can be used for economic purposes.

With proper installation, there's no risk of unpleasant odors around the house. First and foremost, ensure that odors don't enter the interior through sinks, washbasins, toilet bowls, etc., by ensuring that these devices have siphons that are constantly filled with water. Vent and vent connections should be used to equalize pressure in the sewer stacks. The sewer stack (vent) in the building must extend above the roof and terminate with an air vent.
