Ecoline II underground rainwater tank

Ecoline II tanks represent a new and improved generation of Ecoline tanks. The underground rainwater tank is designed for collecting rainwater and sewage. It is used, for example, for private developments in domestic gardens. The new construction is characterised by lighter weight, which makes transportation and installation considerably easier. This reduces associated costs. It is made of high-density polyethylene. The tank is made by rotational moulding. This eliminates joints and welds. This is important because they can create stresses that weaken the structure. As a result, the Ecoline system features a more durable structure and higher tightness.The cover and superstructure are included.

Installation instructions

It is possible to base the tanks in unfavourable conditions. Ecoline is suitable for soils with unfavourable water and ground conditions. These include, for example, a high groundwater level (up to 40 cm from the bottom of the tank) and impermeable - heavy (clay) soils.

Use of ground cover during installation:

Max. 56 cm ground cover - sand backfill (20 cm layer),
From 80 cm soil cover - backfilling with lean concrete B-10 (20 cm layer),
In case of installation in ground with periodically elevated ground water level (up to max. 40 cm), the backfilling should be made with lean concrete B-10 (20 cm layer).

For more details on installation, please refer to the installation instructions, which can be found in the download area.

We also offer kits for using rainwater in the garden:

Advantages of the Ecoline underground tank:

Monolithically manufactured, without seams or welds,
10-year warranty on tank tightness,
Possibility of foundation up to 40 cm in ground water,
Possibility of foundation in soils difficult to permeate,
Lighter weight,
3 DN 100 connections (other dimensions and locations on request)

*Tanks with a capacity of 13,500 and 20,000 litres are available on request. Please feel free to contact us.

Installation diagram for the use of rainwater - Ecoline II Matic

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.

Schemat obliczania pojemności zbiornika na deszczówkę – opad roczny × powierzchnia dachu × współczynnik spływu
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:

If you prefer, open the calculator in a new tab: Tank selection calculator. If you have any problems, please contact our customer service.

Step 4: Tank selection - material

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
Add a filter, pump and collection point, or choose an off-the-shelf solution: Rainwater systems for the garden

FAQ: How to choose a rainwater storage tank

What capacity to start with?

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.
