There are a number of jobs that count various community contributions in your review. This is a very large topic - write a paper in a major journal, give a speech at a conference, submit high profile bug reports - you can get a large raise for it. (the worry of course is that you get a reputation and thus someone gives you a great offer so if they want to keep you they better pay enough that you won’t leave). Exactly what gets you those promotions/raises isn’t clear in part because they need flexibility for someone who honestly discovers a new way to get that reputation and thus they have to give them a promotion. People who don’t deserve the promotion see the policy in place and look for ways to cheat themselves to a promotion they don’t deserve.
Doesn’t Quebec get their water from sources that are replenished by rain and thus have plenty to spare?
