Water is life and an essential resource for the planet's sustainability. However, it is limited and increasingly scarce due to the pressure exerted by drought, excessive consumption , and other factors affecting its availability. Therefore, now more than ever, it is crucial to employ efficient strategies to save irrigation water , both at home and in gardens, urban farms, or larger crops.
The agricultural sector has made significant progress in optimizing water use thanks to systems like drip irrigation , which delivers the precise amount of water at the right time and place. However, conserving water is everyone's responsibility . Below, we've compiled the best tips and tricks for saving water when watering your plants at home, in the garden, in raised beds and pots, as well as in larger-scale installations.
Practical ideas to save irrigation water in your daily life
- Choose plants that require less water. Choose native or climate-adapted species, as well as succulents and cacti, that tolerate drought. If possible, avoid traditional grass due to its high water consumption. For more details, you can learn how to store rainwater for irrigation. this guide.
- Water at the right timeSchedule watering for early morning or late afternoon, when evaporation is at its lowest and plants can absorb water best.
- Use padding or mulchApply a layer of organic materials (dry leaves, straw, bark, wood chips) over the soil to retain moisture, prevent extreme temperature fluctuations, and reduce weed growth.
- Install drip irrigationIt's one of the most efficient systems, as it delivers water directly to the plant's roots, preventing evaporation and waterlogging. It's ideal for gardens, terraces, urban gardens, and large pots.
More efficient irrigation systems to optimize water use
Choosing the right irrigation method is key to maximizing water savings. The most recommended systems are:
- Drip irrigation: Distributes water directly to the base of the plants, minimizing evaporation and allowing you to control the amount of water each plant receives. It can also be automated and programmed to adapt to actual humidity needs.
- Efficient sprinkler irrigationIf you need to water large areas (lawns or crops), opt for low-volume, low-pressure sprinkler systems that distribute water evenly without overspray, and adjust them to avoid watering paths and non-planted surfaces.
- Underground wateringThis involves installing perforated tubes or hoses beneath the surface, releasing water directly at the root. It saves up to 70% compared to traditional methods and is especially useful in windy or hot areas.
- Irrigation by exudation: Uses porous tubes that continuously release water, ideal for rows of plants or table crops, with minimal evaporation losses.
Accessories, programming and maintenance to achieve maximum savings
The use of technology and regular monitoring of the irrigation system are fundamental aspects to avoid water loss:
- Rain sensors and programmers: They automate irrigation and adapt it to weather conditions, stopping watering when it rains and adjusting schedules to avoid waste due to evaporation.
- Soil moisture sensors: They allow watering only when the soil needs it, avoiding both excess and deficit of water in the substrate.
- Pressure regulating and reducing valves: They adjust the flow rate and pressure to prevent leaks, flooding or distribution failures.
- Periodic maintenanceCheck sprinklers, pipes, and drippers regularly for blockages, breaks, leaks, or misalignments. Even a slight drip can waste thousands of liters a year.
Additional good practices and tips for sustainable irrigation
There are other techniques that help optimize water consumption in your garden or orchard:
- Divide the garden into zones based on water needsNot all plants require the same amount of water. Group shrubs, grass, flowers, and trees according to their needs and schedule watering accordingly.
- Leave the grass a little taller in summer: This protects the soil from the sun, retains moisture better and reduces the need for irrigation.
- Use a broom instead of a hose to clean your garden or patio..
- Protect the garden from the wind with hedges or walls to prevent the substrate from drying out too quickly.
- Opt for light fertilization in hot weather; moderate growth reduces water consumption.
Organic mulches and coverings (such as bark, gravel, husks or shells) not only reduce evaporation, but also prevent weed growth and provide nutrients to the soil as they decompose.
In the swimming pool, the use of floating covers reduces evaporation losses by up to 70% and helps to maintain the temperature, allowing for water and energy savings.
Detecting and repairing leaks in faucets, pipes, and irrigation systems is essential. A leaky faucet can waste more than 30 liters of water per day.
Monitor consumption using individual meters and conduct periodic inspections to detect any anomalies in the system.
Water conservation begins with every small action and decision when it comes to watering. With these tips, you can keep your plants, gardens, and orchards in perfect condition, save on your water bill, and actively contribute to environmental sustainability.
