Okay, you have residences with water supplied to them, I guess you need pumping stations, you don't like an ugly industrial building, so you make them blend in,

Okay, you have residences with water supplied to them, I guess you need pumping stations, you don't like an ugly industrial building, so you make them blend in, got it. Somehow the oil wells seem a lot more nefarious, since they aren't needed to be there, and it's a surprising zoning decision (to me) for them to be there. So, do we all think they're at the same level as the pumping stations? Were they just trying to blend in, but otherwise well-understood to be there? Or were these covert operations? I have so many questions, I guess :-)
