Repeal the Water Conservation N.A.P. and the Power Conservation N.A.P.
You can do this quickly with cheats. Use Ctrl-Shift-C to open the cheat console. Use testingCheats on to enable cheats. Shift-click on your Sim's mailbox to bring up a cheat menu. Click on Instant Repeal Neighborhood Action Plan (Cheat) and then choose the plan you want to repeal. Once you are finished, you can use testingCheats off to disable the cheats and then close the cheat console by pressing the Esc key or using Ctrl-Shift-C a second time.
It sounds like you used the options panel to turn off NPC Voting. That's a good idea if you want to be sure these plans don't get voted back in but it doesn't affect the plans that are already in use. The active plans have to be repealed if you don't want them.
