Do you choose the right volume for the recovery of rainwater? – Sweek's advice

It is no longer a secret for anyone, the installation of a rainwater recovery system of the roof is both cheap and durable. Is this system more and more widespread in our homes, just how to know the volume of water that we will need for our future uses? Will our tank be good or too small? How to have no doubts when you don't know how to choose the right volume for your tank? In this article, we will answer all your questions to help you better.

What uses of rainwater do you plan to do?

The first and most important thing to do before choosing the good quality of the storage of its rainwater recovery and, of course, to precisely define the use that you will make of your rainwater. There are two main uses, the first concerns all internal uses: cleaning of floors, laundry washing, water toilet … the second concerns external uses how to clean the car, water the floor, plants and vegetable garden in the garden or the filling of your small fish basin.

Of course, you are not forced to use rainwater for all its uses, and it is precisely what defines the volume of recovery. If you use the recovered water for internal use or only external use, it will obviously require less water than you use it for both your garden and for your home. In the same way, the bigger your home and garden, the more the volume of the tank tank should be. It is therefore essential to determine the surface for water for a garden, for example, or the number of washing machines that are performed per week to measure the number of liters that will be necessary to preserve recovery.

What is your current consumption?

The second thing to do before choosing the tank storage capacity is to know the current water consumption. To do this, nothing could be simpler, just look at your consumption on water bills. Therefore, you will know precisely, the amount of water you need this year. On average, from 40 to 50 % of the waters consumed for the use of the concern of the invoice that do not require drinking water to be used!

In fact, if your invoice has an annual consumption of 200 m3, you can plan to recover an amount from 80 to 100 m3 of rainwater from your roof thanks to your tank. Proceeding the installation of a tank will save you a lot and do a very good good on the planet at the same time.

What is the rain in your region?

It is also interesting to know the rainfall of your region. In fact, although it may seem obvious, rainfall plays an essential role in choosing the volume of your tank. In the vast majority of cases, a small tank will be more than enough in a region where the climate is wet and where it rains often. In fact, the tank will tend to fill up more quickly and this, on a regular basis. On the contrary, if you live in a region where the rain is rare and in which the climate is relatively dry, a larger air recovery is recommended. Therefore, it will take more time to fill, so it will be necessary to allow the water to accumulate so you can use it when there is no rain.

The rain represents the figure corresponding to the volume of liters per square meter from which it will be necessary to subtract 10 % on average due to evaporation. Generally, it is calculated in the millimeter. To calculate it correctly, everything you need to do is multiply everything by the surface of the roof to know the volume and the amount of water necessary for use.

Which roof surface will you connect to the device?

The surface of the roof that you will connect to the device depends on the needs of the water. The more water you need, the more you need a large roof surface.

Therefore, do not forget that you will have to connect a descent of the gutter and that it will therefore be necessary to take into account the different attachments of your roof such as the garage, the garden shelters or even the thin, so as not to be surprised. In the same way, do not forget to place the recovery of water under the roof closest to the use of rainwater. If this water is used to water the plants, place the plane recoverer connected by a eaves, for example close to the irrigation system and your tap. The main thing is that its use is simple and practical so that it becomes a reflection for you.

Note also that it may be necessary to satisfy some constraints. If you opt for a buried tank, system constraints may be needed, you will therefore have to anticipate before choosing your position away from home.

Calculate the volume necessary for the recovery of rainwater is only a simple esteem, it is impossible to know precisely the tank's ability and the amount of water that we will need for its personal consumption, because it flies constantly according to the season, for example. However, making an esteem is not useless and it will allow you to more easily choose the size of the tank tank. With our advice, you are sure to choose an adequate water recovery technique.
