Do You Need a Permit for Irrigation System Installation? in Netherlands
Whether you need a permit for an in-ground sprinkler or drip irrigation system depends on your municipality and the scope of the connection. Most jurisdictions require a plumbing or irrigation permit because the system connects to the municipal water supply and must include a backflow prevention device to protect drinking water. Simple drip systems fed by a hose bib typically don't need a permit, but anything tied into the main line usually does.

Country-specific detail
In the Netherlands, garden irrigation systems (beregeningsinstallatie) connected to the drinking water supply (drinkwaterleiding) must include a terugstroombeveiliging (backflow preventer) per the Drinkwaterbesluit. The local waterbedrijf may need to inspect or approve the connection. Systems using regenwater (rainwater) or grondwater (groundwater) are generally vergunningvrij but must be clearly separated from the drinkwater system. Boring a grondwaterbron (groundwater well) may require a watervergunning from the waterschap, depending on the depth and extraction volume.
