Slow sand filter: installing a float switch to control the water pump

Since the aerobic treatment system (ATS) dumps the water out into a 1 cubic meter cistern below the ground, and the slow sand filter we want to use to filter this is above ground about 5 meters away, we are using a large aquarium pump to pump the effluent in the cistern to the slow…
