The Rijkswaterstaat (the Dutch ministry in charge of water infrastructure and water management) emphasizes that fact at the same time as it acknowledges staff discretion* with the following:

- Be independent
- Be reliable
- Be careful
* In my papers, I have explored how water managers are selfish like us [pdf], how they destroyed sustainability in Southern California, and how bureaucrats (in general) with discretion will serve the public good when they want to.
