The Water reservoirs In Spain can be found in a 55.48% of its capacitysaid the latest update to the Peninsular Hydrological Bulletin published by the Ministry of Ecological Transition and the Democratic Challenge (Miteco). Sunday December 28th.
According to these official data Water storage in the country increased compared to last week.
Spain has a network of reservoirs that play a strategic role in regulating and storing water. Therefore, its constant monitoring is crucial due to the impact of this resource from daily life to all types of industries.

Regardless of the capacity of the reservoirs in Spain, you must always approach their use responsibly. For this reason, Miteco has published a series of tips for saving water in homes, especially in the garden.
In Spain, single-family homes with gardens use two to five times more water than apartments. The garden is therefore usually a large water consumer. But there are solutions to avoid this.
One of the most obvious ways to reduce water use in the garden is to use plants that have low watering needs or that simply do not require watering once they are well established. That doesn’t mean that
We need to fill the garden with cacti and prickly pears. In fact, most of the species traditionally used in our gardens (Mediterranean trees, shrubs and shrubs) are very undemanding when it comes to irrigation.
Typically, more than two-thirds of the water used in a garden is used to care for the grass. Therefore, it is no exaggeration to say that grass is the largest consumer of water in our modern gardens. Therefore, limiting expansion is the safest and most effective way to reduce water consumption.
Covering garden areas with natural materials such as stones or gravel or tree bark significantly reduces water costs while achieving pleasant aesthetic effects. The coatings prevent excessive heating of the soil, protect against wind and erosion, prevent the appearance of weeds and grasses and make it easier to conceal irrigation systems.
Local irrigation systems provide water to plants through “drippers” that irrigate at low pressure. These systems allow each plant to provide exactly the amount it needs and avoid water loss through evaporation. For this reason, they use between half and a quarter of the water that would be required for sprinkler irrigation.
Rainwater that falls on roofs and terraces can be used to water the garden. Once collected through gutters or patio drainage, it can be moved to a small tank where it is stored and then watered.
A small, half-buried tank is ideal for storing rainwater, but we can also use other improvised containers, from a barrel to a drum or an old bathtub. It is advisable to place the tank in a high area of the property to allow for gravity irrigation.
Water during the coolest hours of the day to avoid losses due to evaporation and damage to plants. Also remember that excessive watering makes plants less resistant to drought and more susceptible to disease.
