Put a rainwater collector to water the flowers and the garden for free. Depending on its size and location, it can also irrigate all or part of the garden. And the resulting savings are not insignificant!

Installation of a water recuperator at home

In France, the average price of water is 3 € / m³. But in some municipalities, it can reach 7 € / m³. A quick calculation makes it possible to estimate the savings made with a rainwater collection tank, as long as the house has a garden or vegetable garden.
This recovered water can also be used to wash the car, bicycles, garden furniture, the terrace, etc. Here, the investment for an aboveground tank and its system is about 60 €.
Its implementation is simple and requires only a few hours, unlike buried models, larger and more expensive, which usually require the use of a construction machine.

The roof provider of water

The volume of rainwater recovered depends on the roof area concerned and the rainfall rate of the area. Normal rain, falling regularly during the night, quickly filled a tank of 250 liters from a surface of 50 m².
In order to obtain maximum efficiency, it is necessary to connect the tank to the downflow of rain water. There are several capture systems to be connected directly to the descent (usually equipped with a valve and a filter that blocks impurities).
They settle at a height higher than the maximum level of water in the tank. Here, three 90° elbows are connected to a pipe to direct the water to the hole provided on the tank. Unusual situation: the owner has chosen to directly connect the descent to the tank, because the roof is that of a small outbuilding. It is possible to recover even more water through a cascade system.
This is the principle of communicating vessels. Once the first tank full, the water flows into the second tank (taking care to provide a cover to keep the water out of the light) by a PVC tube that connects the two tanks from above. Just provide a slight slope (2 cm / m) to facilitate the flow of water from the first to the second tank.

Volumes adapted to the needs

In this case, our gardener only wanted a small water reserve of 250 liters to fill a few watering cans for flowers and plants around the house.
The tank, its support, and its faucet cost him about thirty euros in a garden center. As for PVC tubes and elbows found in a large DIY area, they cost substantially the same price.
The support allows enough space under the tap to slide a bucket or a watering can to fill it with water and avoid having to connect a hose, unattractive and especially impractical.

Using the spirit level, check that the support receiving the tank is level.
If necessary, fine-tune the setting by adding or removing soil or stones under its base.

After drilling the hole to receive the faucet at the bottom of the tank, clean the plastic burrs created here by the hole saw (slow speed).

Position the valve in the opening and hold it against the wall of the tank.
Inside, screw the plastic nut onto the valve thread.
Block the whole.

On the top of the tank, drill with a hole saw 1 cm larger than the diameter of the connecting pipe.
Three elbows are required to complete the installation.

Provide two 90° elbows and two PVC tubes.
Make a blank mounting to ensure proper sizing of the installation, then dismantle.

Once the incline of 2 cm per meter determined to the tank, prepare a third bend at 90°.
Saw the descent and nest the elbow in it.

A grid here supports the PVC pipe with a wire.
The slope is adjusted by sliding a screwdriver between the two strands and turning until you reach the desired gradient.

The assembly is not glued, it is possible to change the course of the water as needed.

Practical advice
• Perfect sealing is not essential in this type of installation. When connecting the pipes to the elbows, it is better not to stick them in order to maintain a flexibility of use. In this way, you will have the opportunity to modify, stop, increase the flow of water at your convenience.
• For aesthetic reasons, install the bowl on the side of the house or on the right side of a lower back. It can be hidden by an addiction or vegetation.

❓ How do you make rainwater drinkable?

👉 Water treatment options include filtration, chemical disinfection, or boiling. Filtration can remove some germs and chemicals. Treating water with chlorine or iodine kills some germs but does not remove chemicals or toxins. Boiling the water will kill germs but will not remove chemicals.

❓ What are the disadvantages of a rain barrel?

👉 The main disadvantage is their small size which really limits the potential rainwater collection volume. To increase the rainwater collection capability, you would need to link multiple rain barrels together which increases the connection points and the opportunity for failure or leaks.

❓ Does a rain barrel have to be attached to a gutter?

👉 Rain barrels are usually positioned below the downspout of a roof gutter; however, you can still use a rain barrel if your house doesn't have gutters. You can also attach several rain barrels together with a simple connection kit.

❓ How long can you store rainwater for drinking?

❓ How long will rain water stay fresh?

👉 You probably know the benefits of using rainwater for plants, but how long can you keep it and use it on your plants? Generally, rainwater will become contaminated after about one week. You can prolong its lifetime indefinitely by keeping it out of the light and from animal and insect contact.

❓ Can you drink rain water after boiling it?

👉 Rainwater is generally safe for most people to drink however sometimes it may be microbiologically compromised and have a lower microbial quality than mains water. This is particularly common after rainfall where E. coli levels are sometimes elevated.

❓ Is it better to link rain barrels from top or bottom?

👉 Connecting at the bottom of the barrel is a bit tricky for the closed barrel portion and requires special instructions. We recommend using our Barrel Connector Kits at the top of each barrel where the pressure is minimal; if a leak occurs at the bottom, you will lose your entire water supply.

❓ How do you install a rainwater collection system?

👉 Cover the area around the hole with the metal screen. Place a filter at the top of the downspout. This will prevent leaves and other debris from running down the downspout and creating a clog in your rainwater collection system. Connect the additional barrels.

❓ Do you need a water meter for a rainwater collection system?

👉 In most cases, the company that installs your rainwater collection system will provide you with a water meter before installing the system. In some cases, this is a complimentary product. In other cases, you might wish to purchase your own to be sure you get a system that is ideal for your situation.

❓ How do rainwater collectors collect rainwater?

👉 You can get very simple rainwater collection systems like barrels that sit out in the open and collect rainwater that runs off the roof, as well as much more complicated systems involving pipes flowing from the roof down underground into below-surface tanks.

❓ How much does it cost to install a rainwater harvesting system?

👉 For instance, if you want to install a 5,000-gallon ‘wet’ tank with a sprinkler system, you’ll pay $4,000 to $7,000 for the irrigation and sprinkler installation. Another addition you might want is a water treatment system, which is about $2,500 to $3,000. Neither of these items are required for a basic rainwater gathering system.
