With global warming, water cycles will be disrupted. The recovery of rainwater is a possibility to reduce the risk of water shortage in the garden during summer heat waves. Find out without delay how to choose the capacity of your buried tank to recover rainwater, as part of government measures for the preservation of water resources.
Underground tanks, an innovative solution to meet the economic and ecological challenges of rainwater recovery
Buried tanks represent an advantageous and innovative alternative to traditional above-ground tanks in the field of rainwater recovery. They not only preserve floor space and minimize the visual impact of installations, but also ensure better protection of the water once morest temperature variations and external contamination. These characteristics guarantee better water quality for optimal use.
In addition, the installation of an underground tank is part of an approach that is both economical and ecological. The recovery of rainwater makes it possible to significantly reduce the consumption of drinking water and, consequently, the water bill. The savings made translate into an attractive long-term return on investment. Furthermore, the use of rainwater for non-food purposes, such as watering plants, washing cars or cleaning floors, contributes to the conservation of water resources and the reduction of pressure on groundwater.
As part of the government’s plan with 53 measures for water, underground tanks are the subject of particular attention. Indeed, their use is part of a transition process towards a more sustainable and environmentally friendly society. Underground tanks thus meet the economic and ecological challenges of our time in terms of water management, while offering innovative and efficient solutions to meet the needs of individuals and businesses.
How to estimate your water needs to select the appropriate underground tank capacity for your situation?
In order to determine the ideal capacity of the tank to collect rainwater, it is essential to carry out an accurate assessment of your water needs as well as the specific parameters of your land and your home. This analysis will allow you to opt for a capacity adapted to your requirements and to maximize the efficiency of your installation.
Several key elements should be considered during this assessment:
- The roof surface: the amount of water you can recover depends directly on the surface of your roof. The larger this area, the more rainwater you will collect. Be sure to take into account the entire roof area likely to collect water.
- Local rainfall: The amount of recoverable water varies depending on the rainfall in your area. Find out regarding the average annual local rainfall to estimate how much water you can harvest.
- The intended use of the collected water: depending on the use you plan for the rainwater, the capacity of the tank may vary. If you are considering limited uses, such as watering plants or washing cars, a smaller capacity tub might be sufficient. On the other hand, for more important needs, such as flushing the toilet or washing clothes, a larger capacity tank will be necessary.
- The space available: the size and configuration of your land can influence the capacity of the tank to be installed. If your space is limited, you may need to opt for a smaller tank or consider adapting the installation of the buried tank according to the constraints.
A calculation method to determine the optimal capacity of your tank
If you are considering installing a tank to collect rainwater, determining the appropriate capacity is key to maximizing the benefits of your installation. A simple calculation method can help you estimate the optimal capacity of your underground tank according to your specific needs.
The formula for calculating the required capacity of your underground tank is as follows:
Tank capacity = Roof area × Annual rainfall × Recovery coefficient
- Roof area refers to the total area of your roof that contributes to rainwater collection. This measurement is usually expressed in square meters (m²).
- Annual rainfall is the total amount of precipitation received in your region over the course of a year. You can get this information from your local weather agency or on the Internet. Rainfall is usually expressed in millimeters (mm) or liters per square meter (L/m²).
- The recovery coefficient takes into account water losses due to evaporation, leaks and runoff. It generally ranges between 0.6 and 0.9, depending on the quality of your recovery system and the design of your roof.
By applying this formula, you can estimate the tank capacity needed to effectively meet your rainwater needs. Keep in mind that this estimate must be adapted according to the space available for the installation of the tank and the intended use of the recovered water. Taking these factors into account will allow you to select the optimum capacity for your underground tank and to maximize the ecological and economic advantages of your investment.
Technological advances driving the evolution of rainwater harvesting systems
Technology has proven to be a key factor in improving and optimizing rainwater harvesting systems, especially with regard to underground tanks. The progress made in this field has made it possible to design more efficient, sustainable and high-performance solutions to meet the growing needs of users in terms of water management.
Modular tanks, for example, offer great flexibility thanks to their easy assembly and disassembly capability. They thus make it possible to adapt to the constraints of the terrain and to the evolution of water needs. Additionally, advanced filtration systems ensure better water quality by removing impurities and contaminants found in rainwater, making it safer for various uses.
Furthermore, the introduction of smart management devices has facilitated the maintenance and optimization of rainwater harvesting facilities. These electronic systems control and monitor in real time the quantity of water recovered, the state of the tank and the quality of the water.
These advances have contributed to improving the performance and reliability of underground tanks for rainwater recovery, while meeting current environmental and economic challenges.
Financial aid and incentives for the installation of tanks
In order to encourage individuals and companies to invest in rainwater harvesting systems, several financial aids and incentives have been put in place. Among these, it is possible to cite:
- Subsidies and local aid: some local authorities offer financial aid for the installation of underground tanks. Check with your town hall to find out what measures exist in your area.
- Tax credits: a tax credit for the recovery of rainwater can be granted to individuals who install an underground tank. This measure makes it possible to reduce the cost of the initial investment.
- Preferential rates for eco-loans: some banks offer loans at reduced rates to finance the installation of an underground tank, thus facilitating access to this ecological and economical solution.
To conclude, the choice of the capacity of your buried tank will depend on several factors, such as the surface of the roof, the local rainfall, the planned use of the recovered water and the space available. Do not hesitate to find out regarding the technological innovations and the financial aid available to optimize your investment and contribute to the preservation of water resources.
