Welcome to OpenStreetMap, and thank you for your contribution!

It is topologically incorrect to attach the powerlines to the treatment plant. Generally, features being attached implies some sort of physical connection, such as buildings with a shared wall or roads intersecting. Powerlines should be independent of landuse such as a treatment plant. To avoid this in the future, go into the "Map Data" tab and uncheck "Power Features". I suggest experimenting with the different toggles until you determine which ones are needed.

While Baloo's comment could have been more welcoming and explained the exact issue with your edit, it is certainly not intended to tear down your contribution. Name-calling is unwarranted.
