Mike,

The water level is rising and will almost touch the 4x4 under the panel before the pond reaches it's overflow.

This is a 100 amp service, and as of now, is feeding a submersible pump at one end of the pond which pumps water to the waterfall at the other end. The pump is switched on by plugging an extension cord (which was buried)into the GFI that can be seen under the panel.

They have built an outdoor classroom about 150' from the pond, as well as a nature trail. I have a feeling this service will eventually be serving more than one receptacle. If there was not more planned for the service, they could have run a receptacle circuit underground from the school building when they ran the water to the pond.

As to why the AHJ is ignoring the situation, I am not sure. As stated earlier, the AHJ, as well as the Principal of the school, have been contacted.

I think this work, other than the service, is being done by volunteers. This is another case of well-meaning DIY'ers not knowing the dangers.
