Regardless of the capacity of your tanks in Spain, you should always be responsible for their use. For this reason, Metico has published a series of recommendations for saving water in homes, specifically from the garden.
In Spain, single-family homes with gardens consume 2 to 5 times more water than apartments. The garden is therefore usually a large consumer of water. But there are solutions to avoid this.
One of the most obvious options for reducing water consumption in the garden is to use plants that have modest watering requirements or that simply do not require any watering once they have established themselves well. It doesn’t mean that
We have to fill the garden with cactus and prickly pear. In fact, most of the species traditionally used in our gardens (Mediterranean trees, shrubs and shrubs) do not require much watering.
Typically, more than two-thirds of the water used in a lawn is devoted to maintaining the lawn. So it is no exaggeration to say that grass is the largest consumer of water in our modern gardens. Therefore, limiting its spillover is the safest and most effective way to reduce water consumption.
Covering garden surfaces with natural materials such as stones, pebbles and tree bark significantly reduces water costs while achieving pleasing aesthetic effects. Coatings prevent excessive heating of the soil, protect against wind and erosion, prevent the emergence of weeds and weeds and facilitate the concealment of irrigation systems.
Spot irrigation systems supply water to plants through “drippers” that are watered at low pressure. These systems allow each plant to supply exactly the amount it needs and avoid water loss due to evaporation. For this reason, they use between half and a quarter as much water as sprinkler irrigation.
Rainwater that falls on roofs and patios can be used to irrigate gardens. Once collected through the gutters or yard drain, they can be moved to a small tank where they will be stored and then watered.
A small, semi-buried tank is ideal for storing rainwater, although we can also use other improvised containers, from a barrel to a barrel or an old bathtub. It is recommended to place the tank in an elevated area of the plot of land, so that it can be irrigated by gravity.
Water during the coldest hours of the day, this way you will avoid losses due to evaporation and damage to plants. Also remember that excessive watering makes plants less resistant to drought and more sensitive to diseases.
