Rainwater Tank

Collecting rainwater is considered normal in many parts of the world where there is a developed awareness of environmental protection. Čabar Plast rainwater harvesting tanks represent an innovative and sustainable solution for utilizing natural rainwater resources, allowing for the reduction of potable water consumption and contributing to environmental preservation.

With the increasing need for rational water use, especially in areas with limited access to the water supply network or during drought periods, rainwater tanks are becoming a key element in ecologically responsible water resource management.

We hope that over time, awareness of the usability of rain potential will also rise in our country, especially considering that in our regions, about 30,000 liters of clean water fall on a 50 square meter roof in one year; it would be a shame not to utilize this resource that would otherwise go down the drain.

Water is the foundation of humanity. Many populations today face water supply problems, especially in areas without a developed water supply system or water network.

The average water consumption according to EU standards is about 100l-150l per day (bathing, dishwashing, drinking), and the water must meet strict hygiene regulations.

Čabar Plast produces rainwater harvesting tanks that are made from high-quality HDPE, ensuring:

Water tightness and a long-term solution, as the material only loses 5% of its properties after 50 years of use,
Resistance to UV rays and can withstand extreme temperatures from -30°C to +80°C,
Environmentally tested (do not pollute the environment),
Thermal stability,
Good load-bearing capacity,
Impact resistance, meaning they do not show visible signs of damage,
And importantly, they are easy to install and have minimal maintenance costs.

Čabar plast water tanks as rainwater harvesting systems

In areas with water supply difficulties where there is a lack of sufficient drinking water, we recommend installing our rainwater harvesting tanks. Besides a large water or rainwater tank, they also possess a smaller tank with activated carbon serving as a filter or purifier for the collected rainwater, making the water further usable as technically sound.

Rainwater harvesting tanks represent an innovative and environmentally sustainable solution for water management in households and commercial properties. The main advantages of these systems include:

1.Unlimited water capacity

With a sufficiently large tank or tank system, you can collect significant amounts of rainwater, allowing for abundant garden watering, pool filling, as well as use for laundry, dishwashing, and showering without fear of excessive consumption or restrictions.

Regardless of climate conditions and storage capacity, a rainwater harvesting system can significantly reduce dependence on the municipal water supply, providing almost an unlimited source of water for non-potable needs.

2.Reduced use of municipal water:

Using rainwater for most needs reduces the demand for treated water from the municipal system, conserving resources and reducing the burden on water treatment and distribution infrastructure.

By utilizing rainwater, you contribute to sustainable water resource management, reducing the need for water extraction from natural sources, which can be beneficial in regions with limited or endangered water resources.

3. Lower water costs:

Using free rainwater for most daily needs reduces the consumption of municipal water, directly leading to lower water costs.
While the initial investment in a rainwater harvesting system can be substantial, the long-term savings on water costs often justify the initial expenses, especially in areas with high water tariffs.

4. Easy transport and installation:

Most rainwater tanks are designed to be lightweight and portable, facilitating transport to the location and installation. They can be placed in various locations, including underground, aboveground, or concealed positions.
Systems can be customized to specific needs and space available at the location, allowing installation across a wide range of properties, from residential to commercial.

5. Simple maintenance:

Rainwater harvesting tanks and systems generally require minimal maintenance, which may include occasional filter cleaning and system component inspection.
Modern materials and technologies used in tank manufacturing guarantee durability and corrosion resistance, further reducing the need for frequent maintenance or system replacement.

Considering these advantages, a rainwater harvesting system represents a smart and sustainable investment for the future, offering an environmentally friendly and cost-effective way to manage water consumption.

ESSENTIAL REQUIREMENTS FOR INSTALLING A RAINWATER HARVESTING TANK

If you decide on a rainwater harvesting tank, it is necessary to ensure:

A surface from which rainwater can be collected, such as the roof of a house, building, cottage, or another structure. A mesh for separating moss, bird droppings, leaves, and twigs, known as a mechanical filter, is installed on these surfaces.
Rainwater from the roof passes through the gutter to a pipe leading to a smaller tank that acts as a filter, protecting against pebbles, sand, and other fine particles.
From there, it connects through a drain pipe from the filter to the storage tank, which can be either a horizontal or vertical tank, where the collected rainwater is stored.
Čabar Plast rainwater tanks are equipped with connections for inlet, outlet, and overflow (to allow excess water to escape when the tank is full).

We offer delivery of plastic rainwater tanks in various versions, diameters, and heights at the most competitive prices domestically and abroad.

With Čabar Plast tanks, make the most of every rainfall. Our solutions are designed to meet all your needs – from watering gardens to supplying your household.

Choose the optimal capacity based on the surface area of your roof and enjoy savings and sustainability. Here are some approximate examples:

3000L for small gardens and green oases (min. 50m² roof area)
5000L for watering, car washing, and toilets (min. 100m² roof area)
8000L for complete household use including laundry machines (min. 140m² roof area)
20000L for complete household systems, including showers and dishwashers (min. 300m² roof area)

Čabar Plast also produces meter pits, ventilation pipes, cisterns, tanks, barrels, vertical plastic tanks, pontoons, and catamarans.

6 Steps for Installing a Rainwater Harvesting Tank

Step 1: Location Selection

Choose a location close to where you plan to use the collected rainwater.
Ensure the surface is level and solid to keep the tank stable.

Step 2: Surface Preparation

Prepare the surface by removing grass, stones, and other debris.
If necessary, pour a concrete slab for the tank to sit on.

Step 3: Installation of the Collection System

Connect the gutters to a rainwater filter that will separate leaves and larger impurities before the water enters the tank.

Step 4: Tank Placement

Place the tank on the prepared surface.
Ensure all fittings and valves are accessible and that there are no obstacles to their use.

Step 5: Connecting the Tank

Connect the filtered gutter outlet to the tank inlet using PVC pipes or flexible hoses.

Step 6: System Check

Check all connections for leaks
After the first rain, check the water level in the tank and the system’s functionality

Maintenance Tips

Regular Cleaning– Clean the tank at least once a year to remove sediment and algae.
Filter Replacement– Regularly check and replace filters as needed to ensure water quality.
Freezing Protection– In colder climates, ensure adequate insulation or empty the tank before winter to prevent freezing.

FAQ

What tank capacity do I need?

The capacity depends on the roof area and the average rainfall in your region. A general rule is that 1 square meter of roof can collect about 600 liters of water annually.

How to address algae issues?

Algae can be controlled by regular cleaning, using environmentally acceptable algicides, and preventing light from reaching the water in the tank.

Can i use rainwater for drinking?

Rainwater can be used for drinking only if it is adequately filtered and treated to remove all impurities and pathogens. It is recommended to consult with an expert.

Depending on your household needs, it is necessary to determine the volume of the tank in which you will store rainwater.
