THE IMPORTANCE OF FILTER SAND AND GRAVEL IN …
The purpose of this thick bed of graded gravel is three-fold. First, to furnish a support for the filter sand, which will prevent. the latter from being washed into the strainers. Second, to allow. the clear water to pass freely and uniformly from the filter to the underdrainage system when filtering.

Sand vs. Gravel for Backfill: Which Is Right for Me?
Gravel (depending on the type) runs between $10 and $50 per ton, while sand goes for between $5 and $30 per ton. Again, you might find sand cheaper or more expensive than gravel, but not by significant amounts depending on each type. Specific Uses for Sand and Gravel. You may need a straight-up list of things to use sand or gravel with.

Rapid Sand Filtration | SSWM
Rapid sand filtration, in contrast to slow sand filtration, is a purely physical treatment process. As the water flows through several layers of coarse-grained sand and gravel, relatively large particles are held back safely (DIJK & OOMEN 1978). However, RSFs never provide safe drinking water without adequate pre-treatment and final disinfection.

Sand vs. Gravel: Which Is Better for Drainage?
Pitting Sand Against Gravel. The short answer here is that gravel is better for drainage than sand, but that's only the case if you're looking for the highest flow rates. Since gravel has larger particles, there is more room for air — and more importantly, water — to pass through. However, if you're trying to control the exact amount ...
