Standard garden set with Ecoline Slim rainwater tank

Complete rainwater storage tank with filter and automatic pump for the use of rainwater in the garden

Functional description

Rainwater is collected by a guttering system from the roof surface and directed through downpipes to an underground filter from where it flows by gravity to the Ecoline Slim tank. A Pedrollo TOP Multi Tech pump was used to distribute the water. The combination of a garden hose and a premium cover equipped with a water intake allows the rainwater stored in the underground tank to be used, for example, for watering the garden.

The Ecoline Slim tank can be matched with:
  • Scope of delivery:

  • Ecoline Slim rainwater tank

  • Manufactured monolithically, without seams or welds,
  • Guarantee of 10 years for tank tightness,
  • If the tank is to be founded at a depth of more than 50 cm (from the vault), then a 20 cm skim concrete backfill must be made.
  • Possibility of partial foundation in ground water, see instructions for details.
  • Can be founded in ground which is difficult to permeate; if the settling tank is installed in clay or silty ground, the tank should be protected with lean concrete.
  • Low profile,
  • 3 DN 100 connections (other dimensions and locations on request)
  • Installation instructions

  • There is a possibility of founding the tanks in unfavourable conditions. Ecoline Slim is suitable for soils with unfavourable water and ground conditions. These include, for example, a high groundwater level (up to 55 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 soils with periodically elevated ground water level (up to max. 55 cm), the backfilling should be made with lean concrete B-10 (20 cm layer). Please refer to the instructions for details.
  • Please refer to the instructions for more details regarding installation - please refer to the information.

  • Ecoline Premium cover with water intake and ascending pipe

  • The reservoir cover is made of polyethylene - ideal for pedestrian traffic in green areas. The Ecoline Premium cover is offered with water intake for convenient and easy rainwater management. The manhole superstructure, the so-called ascending pipe, is 45 cm high and has a diameter of 60 cm. A rising pipe telescope can be added to extend the manhole. There is a DN 600 seal at the manhole, which protects the rainwater storage tank against the ingress of pollutants from outside.

  • Filter basket

  • The filter basket is recommended for roof areas of up to 350m2. It has dimensions: Ø 410 mm, height 160 mm (filter mesh size - 0.9 mm). Fastening ropes and a hook are included with the basket.

  • Pressure hose

  • Pressure hose used to connect the pump to the water intake, located in the tank lid.

  • TOP Multi-Tech II automatic pump

TOP Multi-Tech II pump *
TOP MULTI-TECH pumps are recommended for pumping clean water and liquids that are not aggressive to the pump material. Due to their high efficiency and reliability, the pumps are used to supply drinking water tanks and wells, to draw rainwater from cisterns for water gardens or for use in irrigation systems, etc.

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.
