Rainwater harvesting is not a new technique for watering a vegetable garden. It is a classic solution because of the scarcity of water. This allows you to benefit from free quality water for your plants. Here are a few tips to help you choose a rainwater harvester.

What are the advantages of using rainwater for your vegetable garden?

Using drinking water for watering the garden is an economical solution. Nowadays, water is becoming scarce and expensive. So, by recovering rainwater, you can limit your water expenses. This will reduce your bills. You will also contribute to the preservation of the planet’s resources. Nature will thank you for it.

Faced with the pollution of rivers and phatic aquifers, drinking water also requires various treatments. These processes are long and complicated. By reducing your consumption of tap water, you will contribute to the reduction of these various processes. Rainwater does not need treatment for your vegetable garden. It is naturally soft and contains no chemicals. The acid it contains is light and compatible with the favourable conditions of the vegetable garden.

What material is used to collect rainwater?

The idea is to recover the rainwater that runs down the gutters of your roof. To do this, you can install a water collecting device on your eavestrough. This equipment collects the rainwater directly and passes it over your gutter to a large container. A tank can hold a large amount of water. There are different models, such as plastic, wooden, stone, etc. Just choose the size according to your needs. Choose a bowl with a lid to keep the water clean. Otherwise, simply place a small grid at the entrance of the cube so that leaves or insects cannot enter.

You can also choose a concrete tank for a durable rainwater harvester. The idea is to build a tank made of concrete. This material can withstand all circumstances. It is waterproof and hard and is resistant to cold and humidity under the ground.

Construction plan for an underground rainwater harvesting tank

The construction of an underground rainwater harvesting tank is carried out under certain conditions such as the available space, the foundation plan, etc. Before proceeding with the installation of a tank, the technicians in charge of this first carry out a feasibility check. This is a study carried out in the field.

This construction is more expensive because of the costs associated with the excavation. Different materials are recommended, such as steel, concrete, etc.  In the case of new construction, earth-moving equipment is required to bury the tank. In this case, the water is kept in a safe environment away from light and at ground temperature. This environment is not conducive to the formation of bacteria and algae.
