    Rainwater Harvesting Tanks

    Don’t know which of the rainwater tanks to buy?

    We will advise you. Everything is of course up to you, but a few tips about advantageous of different rainwater tanks and how to best save money can be useful.

    At the beginning, you should think carefully about what you will use the tank for.

    You purchase a rainwater storage tank, in which you collect water during intense rains and use it during dry months for:

    1. watering the garden

    2. flushing the toilet or washing clothes in the washing machine.

    This will save drinking water and money for drinking water. In addition, you can reduce the cost of purchasing a rainwater tank by up to 50% when you apply for a subsidy from the rainwater subsidy program if you’re in the Czech Republic. (www.dotacedestovka.cz).

    Despite all the pluses, be careful what you buy! You could buy a tank that does not fulfill the function for which it was purchased.

    Some vendors sell tanks that automatically fill with drinking water as soon as the rainwater is used up, and are then able to receive additional rainwater only when it is pumped out. Their goal is to keep the container full, but that’s not what you’re after.

    Tank size

    Another important thing to think about is the size of the tank. You might think that the smaller one is enough for you. It is cheaper and therefore you save. It’s not true. When it rains, the small container fills with water. A drought will come and in a few weeks you will pump out all the water. For the next 2 months you will have to water with potable water. Does it even make sense to get such a tank? The smallest one is perhaps the cheapest at first glance, but due to the cubic meters it is more expensive. For example, you will pay 30,000 CZK for a tank volume of 4 cubic meters and 42,900 CZK for 8 cubic meters. The increase in cubic meters is 2-fold, but the prices are only 1.4-fold. A larger tank is therefore not only more economically advantageous, but you can accumulate water in it for the entire dry season and water the garden, or use it for the toilet and laundry without using drinking water.

    The main thing is of course the size of your garden and roof. The bigger the roof, the faster you can collect water. The bigger the garden, the more water you will use.

    Therefore, contact us and we will advise you to buy the best tank for you. We will respond to your mail, talk to you via mobile phone and WhatsApp, or write to you via Facebook and Instagram.

    The Kolomaki company presents Profi and Planus rainwater tanks.

    Profi rainwater tank

    PROFI is a self-supporting, professionally manufactured tank made of polypropylene in the shape of a cylinder. Its concept is thought out in detail and is designed to meet all the needs of a customer who is interested in collecting rainwater. It is equipped with a rotating hatch to prevent anything from accidentally entering the tank during water pumping, a walk-through hatch, an inlet with holes for hoses and cables, an integrated ladder for convenient access to the tank.

    For better stability, it is intended for horizontal laying. The wall thickness of the cylinder is 8 mm. For greater strength, the tank is equipped with: reinforcement of the side walls from the inside and outside, reinforcement of the cylinder and supports. The circular side walls are 15 mm thick.

    It often happens that the installation of the tank in depth is not possible, or it is associated with a great risk: groundwater, clay soil, boulders, etc. Plus, sometimes it is not acceptable to suffer large costs for the export of excavated soil and the import of a large amount of construction materials. It is for these situations that Kolomaki has developed the tanks and the well-thought-out Planus installation system. A unique solution for shallow installations with minimal earthwork and soil transportation costs.
