Disposal of Sand

[hillbillyreefer]

Spread it on the lawn in a thin layer, spray it down with a hose or wait for it to rain, it'll disappear into the grass and you'll never notice it.

DO NOT put it down the drain, it will just silt up and help plug it off. Then when it rains the water will have nowhere to go and your basement will get wet. Yes that is a bit tinfoil hat like but seriously, don't put sand down any drain.
