Rainwater collector Speedy
Rainwater collector Speedy is designed for filling tanks for rainwater. Equipped with a screen perfectly fulfills its function at rainwater pipe with diameters from 70 mm to 100 mm. Because the collector is flexible during installation is not necessary to cut the gutter enough to drill a hole. The set includes: seal, connecting hose 1 ¼`` 32mm, jigger saw. Rainwater collector is in dark gray and fitted with a shut-off valve.
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.
