My wife wants to take advantage of the large sand bar on our property. She wants to sell the sand. Sand is a good little side business up here. Not many sources.
It seems to me a sand dredge would be a lot simpler than having people in the river pulling out sand with baskets. Which is what the neighbors do.
Anyhow I have a pump that could run a 6 inch dredge, but I can only find 4" suction hose. I have heard that there is some black flexible pipe available, but I don't know where. I am in Chiang Rai province, but I could have it shipped from elsewhere. Any ideas?
