Ok got it.. all this to save water.. Here we dont have that problem ;-)

so your problem is that to save water you spend electricity.. So you want to
save on electricity, but to do so, you will now start loosing water with the
use of a switch, making this whole system useless....

I think you should start looking at the problem from an other angle..

Could you use some solar panel to supply electricity to some battery pack
that could provide power to an inveter that would feed the pump, saving
money, and water while keeping the system working and still respecting any
code....
