I have a shallow well that fills up with very fine silty sand . I need to have this sand vacuumed out each year . This summer , the sand has re-entered my well very quickly ( one week ) . How can I prevent this sand from seeping in ?

My well is about 18 feet deep , with concrete tiles about 3 feet in diameter . It fills up about 3 feet of water ...right now the sand is about 1 foot from the top of the water level .

I noticed that the walls of the tiles have shifted and there are gaps between various tiles ...I think the entire well has sunk into this sand and shifted . If I rebuild the entire well , how can I prevent this sand from invading ?
