Recovery of rainwater, also known as storm water retention, is a relatively simple method to implement at home to receive free water to do laundry, watering the garden, feed pipes from toilets or fulfill its pool. What are the best solutions to recover rainwater? Here’s a little comparative tanks and skimmers needed to install a home system for recovering rainwater.

The recovery and aboveground tanks for storm water retention

These tanks are connected to the gutters of your home, equipped with a filter to discard the leaves and debris, and have an average capacity of 200 to 500 liters. Allow at least 40 euros for the purchase price, prices can rise depending on the capabilities and aesthetics of the tank above ground.

They have the advantage of being placed inside or outside: in the garden out of sight in the cellar, in a garden shed. These tanks have a capacity variable. If they fit your specific needs, they are not particularly aesthetic.
# The vats or tanks rigid: the tall bins are rigid and therefore relatively stronger than flexible tanks. They resist including much better UV and shock or snags. They occupy more space in height but less floor space than the bladders, while being relatively unattractive.
# Tanks ” deco “-like choice of flower boxes or giant amphorae” ancient “, or simply covered with wood, these external tanks above ground may be a good choice aesthetic while providing good recovery of rainwater.

Advantages, disadvantages and cost of the tanks to bury

There are also models of tanks recovery of rainwater to bury. These skimmers have the advantage of being principal of a very large capacity they can hold up to 20,000 liters of water, depending on the model.These models of recovery of rainwater can be buried in the garden, or under the house. The water is protected from light, climatic variations, from freezing. These systems more expensive to buy (from 1,000 to 10,000 euros on average according to capacity) provide power efficiently throughout the home for household needs (health, household appliances, swimming pool). This type of system also allows you to switch back to the supply circuit when the conventional water tank is empty the pump tank is then automatically reconnects on city water.

The benefits of the recovery of rainwater, bonuses to the facility

From an ecological standpoint, you are autonomous water for most of your needs, avoiding exhausting water aquifers, which is an effective technique for the preservation of natural resources. Also, if you have your own supply of water stored, you will escape the restrictions imposed on the use of water in case of excessive heat.
