From my duckweed sump into a 210 litre drum sunken into the ground.
This gave me the advantage of having an extra level.
This was my pump sump and using a level control in this sump I circulated my water back to the dam under pumping pressure in cycles of 10 min of and 18 min pumping. (Piping from pump to dam Ø40 mm)
