Rainwater harvesting is an ecological and economical solution for reducing your consumption of drinking water. By using this natural resource for domestic purposes such as watering, cleaning or toilets, you reduce your water bills and your environmental footprint. Here’s a complete guide to installing a rainwater harvesting system.
The benefits of rainwater harvesting
Savings on water bills
Using rainwater for non-drinking purposes can significantly reduce drinking water consumption.
Preserving natural resources
By harvesting rainwater, you contribute to the sustainable management of water resources.
Versatility of use
Rainwater can be used for watering the garden, outdoor cleaning, toilets and certain household appliances.
Components of a rainwater harvesting system
Gutters and downspouts
Gutters collect rainwater from roofs and direct it to a filtration or storage system.
Filters
A filter is essential to remove leaves, debris and sediment before the water enters the tank.
Storage tank
- Overhead tanks: Easy to install, they are suitable for small volumes.
- Underground tanks: Discreet and capable of storing large quantities of water, but requiring excavation work.
Pump
A pump distributes the reclaimed water to points of use, such as outdoor taps or toilets.
Overflow system
The overflow drains excess water from the reservoir into a drain or garden.
Distribution systems
Special pipes connect the reservoir to the points of use.
Steps for installing a rainwater harvesting system
Step 1: Planning
Identify your water needs and the uses you wish to cover with rainwater. Choose the location of the tank (above or below ground) according to the space available and the quantity of water to be stored.
Step 2: Installing gutters and filters
Make sure gutters are in good condition and properly connected to downspouts. Install a filter at the system inlet to trap debris.
Step 3: Site preparation
- For overhead tanks: Place the tank on a flat, stable surface, such as a concrete slab.
- For an in-ground tank: Dig a pit the size of the tank and install a solid base to support it.
Step 4: Installing the reservoir
Place the reservoir in its intended location and connect the downpipes to its inlet. Install the overflow to drain off excess water.
Step 5: Adding the pump and pipes
Attach the pump to the tank outlet and connect it to the points of use via specific hoses. Check that the pump is suitable for the pressure required for your application.
Step 6: System test
Test to make sure water is flowing properly through filters, tank and points of use. Also check for leaks.
Tips for a successful installation
- Regular maintenance: Clean filters and inspect reservoir for blockages or sediment build-up.
- Use quality materials: Choose resistant components to guarantee the system’s durability.
- Check compliance with standards: In Belgium, certain regulations may apply to the use of rainwater for domestic purposes.
Mistakes to avoid
- Undersizing the reservoir: A reservoir that is too small is likely to overflow frequently in the event of heavy rainfall.
- Forget the overflow: Without an overflow system, excess water can cause overflows or damage foundations.
- Neglecting maintenance: An unmaintained reservoir can become a breeding ground for bacteria and algae.
