[QUOTE="shivan, post: 121787, member: 194"] I can only go on the conversation i had... But when they were bringing up turbidity it had nothing to do with pumps but sluicing in gerneral...... yes he was talking about river sluices. The pumps they said were not legal as they were mechanical, even though they only process water and are aloud under the water act. It is very hard to do much about turbidity from a river sluice as it needs flow to work. Highbankers on the other hand have ways to avoid or minimise turbidity (just don't run straight back into the water course) unless set up in the middle of the creek/river. The area you are digging also would make a difference, sand and gravel will make a lot less turbidity than and area heavy with silt or clay. [/QUOTE]
