14.1: Groundwater and Aquifers
An aquifer is defined as a body of rock or unconsolidated sediment that has sufficient permeability to allow water to flow through it. Unconsolidated materials like gravel, sand, and even silt make relatively good aquifers, as do rocks like sandstone. Other rocks can be good aquifers if they are well fractured.

Therefore, as discussed in Chapter 3, in the case of sand and gravel deposits it is important to determine the relative proportions of the 'sand' and 'gravel' sizes. All plants should be provided with sufficient monitoring instrumentation, e.g. mass flow meters, sampling points and control
Working of Pressure Sand Filter (PSF) in detail
Working of Pressure sand filters (PSF) 1: Water is passed through multiple layers of graded sand, pebbles, and gravel layers in a pressure sand filtration. 2: The media bed in the water filters the contaminants, and the …
Alluvial Fan
An alluvial fan is a triangle-shaped deposit of gravel, sand, and smaller materials called alluvium.
Technologies
Gravel layers below the coarse sand support the medium and prevent the drain from clogging with sand. The gravel should not be displaced by the backwashing procedure. General plant maintenance will also be needed (e.g. application of anti-corrosive agents to metal parts, lubricating valves).

A sand filter makes use of sand to filter water. The dirt from the water is left behind in the pores of the sand. Read more about sand filters in this article.
Build an Active Gravel Bog Filter
This mission is accomplished by pumping pond water evenly though a gravel bed via a grid of perforated pipework. The gravel provides the surface area for nitrifying bacteria to colonize. The bacteria reduce fish and plant waste into plant food. Growing in the gravel are bog plants that take up the plant food.
