A trash pump can work I'm sure but you still would need to create either some sort of holding pool to let the sediment fall out of the water or a filtration system. I would stray away from using a water driven pump as it almost always has an impeller of some type and for suction purposes even muck/sand will start to mess with the internal bearing and seals leading to premature wear. I bet you could also move the sand pretty quickly if you sucked clean water with your trash pump and used the discharge to blow out the sand.That water depth is going to be troublesome for a true airlift(However we have used them in as little as 4' of water but we use very large roto-screws like Ingersoll Rand 375 XP's: Which can put out around 300 to 400 something CFM). ![]() One guy even told me he could move sand just as quickly with the trolling motor as he could scoop it out with a small excavator. Lots of them take a trolling motor and use it to blow the sand out of their channels. I don't know if this will help you with your problem, but we have a lot of shallow water around here and people's boat slips are always filling up with sand. Thinking it might be easier to rent a trash pump once a year, and just clear the sand away when we get late in the season and they aren't keeping the river level as high. ![]() I'd extend my suction pipe, but I'm about there on vacuum level now on the Cornell pump. Would a 3" trash pump act as dredge to remove sand from a river bank area, along the water edge? I need to do some work around where our riverscreen ( ) sets to be able to better keep it accessible to water. Got a question for anyone that has dealt with sludge/trash pumps.
