Home-garden system with Rain Console ECO with F-Line tank
Rainwater management system for garden watering with automatic irrigation, toilet and washing machine supply using Rain Console Eco
Description of operation
Rainwater is collected by a gutter system from the roof surface and directed through downpipes to an underground filter from where it flows by gravity to the F-line tank. A submersible pump pumps the water to the sanitary facilities (toilet cistern, washing machine) in the building. The system is equipped with a rainwater Eco console which controls the water supply to the sanitary facilities (WC, washing machine, garden watering) and in case of lack of rainwater automatically replenishes the tank with tap water, but only up to the safe level of the pump, the continuity of the installation is ensured.
The system is ideal for situations where you have a significantly remote tank from the technical room and where you have an automatic irrigation system with significant hydraulic parameters.
Tank cover TopCover + Upgrade tube extension VS 20 + Spacer ring with 2 gaskets
Tank cover designed for pedestrian traffic. Made of double-walled polyethylene, with child protection. The VS 20 ascending pipe extension is 235 mm high, Ø 600 mm. The ring is 600 mm high and is adjustable (telescopic).
Rainwater filter Drop (Opti)
The Opti underground filter is used to clean the rainwater of solid particles, such as leaves. It also provides protection for the pump against clogging and damage. It is particularly suitable for use in rainwater management systems. The Opti filter is designed for roof areas of up to 200 m2 . A deeper foundation is possible with the use of an extension.

Opti filter extension
Elevating (extension) pipe for the Opti filter. Allows a deeper foundation for the filter. Extension height: 700 mm. The extension can be shortened to 75 mm.
The Rain Console Eco uses a controller to control the pressure pump to distribute rainwater to domestic uses such as washing machines and toilets, but also diverts water to the garden for watering. The Eco Rain Console, together with the pressure pump, works identically to a rainwater panel. The console monitors the water level in the tank and, in the event of a rainwater deficit, replenishes the tank with tap water only up to a preset level so that the pump is able to operate safely (it does not top up the tap water by filling up the entire tank).
PressureWave GWS 35LV diaphragm tank
High-quality 35 litre pressure vessel from the PressureWave range. The PressureWave diaphragm vessel is designed for: booster systems, systems subject to thermal expansion, irrigation and hydraulic shock attenuation. The robust construction and innovative technological solutions ensure a long service life. A top quality product. The diaphragm tank maintains constant water pressure in the system. Limits too frequent pump start-ups.
Top Multi-Evo II pump
MULTI-EVO pumps are recommended for pumping clean water and liquids that are not aggressive to the pump materials. Due to their high efficiency and reliability, submersible pumps are used to supply water tanks and wells, to draw rainwater from cisterns for water gardens or for use in irrigation systems etc.

Floating suction basket 1 1/4"
Floating intake for multi-stage submersible pumps. Connection diameter 1 1/4". Thanks to the float, the intake always floats approx. 15-20 cm below the water surface, from where it is possible to pump the cleanest water from the tank (various impurities may float on the water surface)

This short guide will help you choose the right capacity for your underground rainwater storage tank - without difficult formulas. We will show you how to estimate your needs, count the amount of water from your roof, select the capacity and plan a simple garden installation.
Step 1: Determine what you will use the rainwater for.
List the uses: watering the garden, flushing toilets, laundry, washing the car, housework. This will allow you to estimate the real need for water in a typical week.
Garden watering - take a guideline of 20-25 l/m² per month per season.
Toilet flushing - approximately 35-50 l/person/day.
Laundry - approx. 15-20 l/person/day.
It is advisable to select a tank for 2-3 weeks of typical use - in practice there is no point in storing 'for the whole year'.
Step 2: How much water you collect from the roof (no complicated formulas)
In simple terms, assume: annual rainfall × roof area × runoff coefficient. For most roofs, you can assume a coefficient of around 0.9 (depending on the roofing and the layout of the gutters).
Brief example: calculation of possible rainwater yield
Roof 120 m², annual rainfall ~600mm (approx. 600 l/m²). Estimate: 120 × 600 × 0.8 ≈ 57,600 l/year. This figure helps to select the capacity for a period without rain. And a period without rain can last for 3 weeks. Therefore, you must divide the result by 21 days. That is: (57600 l /365 days)*21 days = 3314 l, the result according to the estimation should be taken as a minimum. Therefore then we choose 4000l , 5000l, 6000l tanks - because of how we will use the rainwater.
Step 3: Selecting the tank capacity
It is most practical to select a tank that will store a supply of water for 2-3 weeks of your needs.
How to calculate capacity: annual rainfall × roof area × runoff coefficient ≈ annual amount of rainwater to be collected.
2000-3000 l - small garden, 1-2 people.
4000-6000 l - family of 3-4 people + garden 200-300 m².
8000-10 000 l - larger garden, intensive watering. 300 m² - more , and with automatic watering.
But you will do this more precisely using the selection calculator below:
In detached houses, underground rainwater tanks are the best choice - they do not take up space in the garden, provide stable temperatures, no water freezing and allow larger capacities without affecting aesthetics.
The best material is PE, HDPE, MDPE plastic - it is lightweight, corrosion resistant, easier to install and above all airtight for many years . It is worth paying attention to water and ground conditions. If the ground water level is high or the soil is clayey, flat tanks such as the F line, Bolt, Eco line Slim, etc., are the best choice. On the other hand, if the conditions are normal, any solution can be used. If you have any problems, please contact our customer service.
Step 5: Simple installation in the garden
The simplest arrangement: gully filter in front of the tank or basket filter, underground tank, floating intake, automatic pump and point of use (tap). This makes watering convenient and economical.
Summary:
Estimate the weekly consumption (garden + house).
Calculate the roof potential (rainfall × area × ~0.9) and divide by 365 days and multiply by 21 days ( 2-3 weeks of drought).
Select an underground storage tank taking into account the yield (calculated from the roof area) and contrast it with the consumption e.g.: water in the garden. Select capacity
For example: family of 3-4 people + garden of 80-150 m² → 4000-6000 l usually works well. Larger garden / intensive watering → 8000-10 000 l. Verify with the calculator above.
Is it possible to supply toilets with rainwater?
Yes - using a suitable system (rainwater control unit/automatic switchover) and filtration.
What about excess water?
Plan an overflow to an infiltration or rainwater drain in accordance with local regulations.
