Rainwater collectors: a sustainable approach and savings!


Preserving the resource, but also saving on the water bill by watering your garden, balcony or terrace copiously, cleaning your car even in the event of water restrictions in summer, these are good reasons to opt for a rainwater collector!

How to choose a rainwater collector?

The most practical way to collect rainwater is to install the collectors under the roof; The water collected in the gutters flows into them through a collector.

The choice of one or more rainwater collectors will be made according to individual needs (number of people making up the household, area to be watered, use, etc.) but also according to financial possibilities and practical and aesthetic criteria.

A simple calculation allows to know the possibilities in recovery according to the configuration of the premises: it suffices to multiply the roof surface by the average annual rainfall (in mm / m²). Thus, the volume of the recuperator can be determined as well as the possible choice of installing several models if the needs are greater. Count 15 l / m² of garden.

A collector with a minimum capacity of 1000 liters is a good choice in most cases, especially if the summer is dry. It remains to choose the model! The outdoor recuperators are light and easy to set up, they are also less expensive than the underground models, however the latter have a larger capacity and also allow domestic use.

Water collectors for all tastes and budgets

The outdoor water collector: there are many models of rainwater collectors available on the market, in various shapes, colors and sizes (from 200 to 2,000 l) that can best integrate into the environment or even add a decorative touch. These recuperators are placed near the facade both in the garden and on a balcony or terrace. In the shape of a barrel or an amphora, imitating a wooden cladding perfectly or adopting a contemporary design, they adapt to the style of each home. Count between 30 and 500 € depending on the volume and design.

The buried recuperator: in a garden, a buried tank may be considered, if the nature of the soil allows it and the cost of the work is within your budget. Very large collectors hold up to 10,000 liters of water, they can be made on site from concrete, but polyethylene models are more convenient. Conveniently connected to the domestic circuit by means of a pump, the rainwater collected in the underground tank will be used to supply the flushing water or household appliances such as the washing machine, it will also be used for watering the garden or cleaning of outdoor equipment. Count between 4,000 and 8,000 € for a collector of 10,000 liters, installation included.
