Results and Savings with Smart Irrigation
Smart irrigation offers tangible benefits, such as cost savings and healthier gardens.
Water and Cost Savings
With smart irrigation systems, water usage is adjusted based on factors like weather conditions and soil moisture. Water is therefore only provided when truly needed. This leads to less water usage and lower costs. How much you save depends on factors such as the size of your garden, the climate in your region, and the system settings.
Healthier Plant Growth
Plants directly benefit from a well-adjusted water supply. By providing water at the right place and time, plants develop stronger roots, are more resistant to diseases, and grow more robustly. In addition, preventing overwatering or drying out creates a balanced ecosystem in your garden.
This approach not only results in a beautiful garden but also prevents issues like root rot, further supporting the overall health of your garden.
Efficient Use of Resources
Smart irrigation systems help use water more efficiently, contributing to a responsible management of water supplies. The system adapts to changing conditions, such as rain or seasonal changes, reducing pressure on water sources. Additionally, well-managed watering promotes healthy soil, which is also beneficial for insects, birds, and other small animals living in your garden. All this helps maintain the quality of groundwater and soil.
Setting Up Your Smart Irrigation System
Want to benefit from a more efficient irrigation system? Here's how to approach it smartly.
Choosing the Right System
When choosing a smart irrigation system, consider the size of your garden, the planting, and your budget. For small gardens up to 100 m², a basic set with a central controller and 4-6 zones is often sufficient. For medium-sized gardens (100-300 m²), you may need a system with 6-12 zones and additional sensors for precise operation.
What to look for when purchasing?
- Ability to manage zones individually
- Compatibility with your wifi network
- Availability of a Dutch app
- Weather-resistant components
Once you have a good system in mind, you can start with the installation.
Installation Guide
1. Preparation
Ensure you have all materials and tools ready. Check that the water pressure is at least 2 bar, as this is necessary for proper operation. Draw a diagram of the piping and wiring.
2. Basic Installation
Connect the main controller to the water source, lay the main pipes, and install the zone valves at strategic locations. Dig trenches 30-40 cm deep for the pipes.
3. Fine-Tuning
Test all components before closing the trenches. Adjust the sprinkler heads so that they only water the desired area, without wasting water.
Maintenance and Troubleshooting
Regular maintenance is essential for your system to function properly. Check the following each spring:
- Possible clogs in sprinkler heads or drip lines
- Leaks or damaged connections
- Operation of the sensors
- Software updates
Experiencing issues like uneven water distribution or malfunctions? First, check for clogged filters, incorrect pressure settings, or a weak wifi connection. Flush the system in winter to prevent frost damage.
Adjust the settings per season and align them with the growth phases of your plants.
Extra Water-Saving Methods
Besides using smart irrigation systems, there are other ways to save water in the garden.
Rainwater Harvesting
Harvesting rainwater is a simple way to use less tap water. A 200-liter rain barrel can make a big difference in a small garden. For larger gardens, underground storage systems are a convenient option, with capacities ranging from 1,000 to 5,000 liters.
Useful Tips:
- Use a filter in the downspout to keep out leaves and debris.
- Place the rain barrel on a stable, flat surface.
- Ensure an overflow system to dispose of excess water.
- Use a submersible pump to easily distribute the stored rainwater.
Soil Improvement and Mulching
A healthy soil can better retain water, significantly lowering the water needs of your garden. With the right techniques, you can make the most of this.
Improving Soil:
- Mix compost through the top 20-30 cm of the soil.
- Add organic material to improve soil structure.
- Check the pH level and adjust it if necessary to 6.0–7.0.
Mulching: A mulch layer of 5-7 cm thick helps reduce evaporation by up to 70%. Suitable materials include:
- Wood chips for ornamental plants and shrubs.
- Straw for vegetable crops.
- Cocoa shells for borders (layer thickness of 3-5 cm).
Drought-Resistant Plants
Choose plants that are resilient to dry conditions. These species require less water and can better handle periods of drought.
