What are percolation ponds?
Percolation ponds are water supply facilities, built strategically in areas where gravel and permeable material allow water to seep into our aquifers. Their primary and most important purpose is to allow water to filter underground.
What is percolation in agriculture?
Percolation is the downward movement of water within soil. The rate of percolation is affected by soil characteristics, with water moving through coarser soils more quickly than through fine- grained soils.
How does a percolation tank work?
How does Percolation Tank look like? Percolation tank is an artificial reservoir which are constructed across stream, submerging a land area with adequate permeability to facilitate sufficient percolation to collect surface water run-off and allow it to percolate within the permeable land.
What is a percolating well?
It is a shallow excavated trench filled with gravel or crushed stone that is designed to infiltrate stormwater though permeable soils into the groundwater aquifer. A percolation trench is similar to a dry well, which is typically an excavated hole filled with gravel.
What is the purpose of percolation?
Percolation can be used to predict water transport factors such as the rate of leaching, or the flow of materials into water. This is most often used in agriculture to determine the movement of fertilizers or the salt content of soil.
What is the process of percolation?
Percolation is the process of a liquid slowly passing through a filter. It’s how coffee is usually made. Percolation comes from the Latin word percolare, which means “to strain through.” Percolation happens when liquid is strained through a filter, like when someone makes coffee.
What is percolation in irrigation?
Deep percolation (DP) refers to the flow of water below a crop root zone (Bethune et al. 2008; Liu et al. 2006). It can be initiated by excess irrigation and/or rainfall input. The purpose of irrigation is to avoid soil moisture deficit so that crops are not stressed.
What is the importance of percolation of water?
What is the purpose of percolation tank?
The percolation tanks are mostly earthen dams with masonry structure only for spillway. The purpose of the percolation tanks is to recharge the ground water storage and hence seepage below the seat of the bed is permissible.

What is aquifers in the water cycle?
Aquifers are a huge storehouse of Earth’s water and people all over the world depend on groundwater in their daily lives. The top of the surface where groundwater occurs is called the water table. In the diagram, you can see how the ground below the water table is saturated with water (the saturated zone).
What causes percolation?
Water infiltrates the soil by moving through the surface. Percolation is the movement of water through the soil itself. Finally, as the water percolates into the deeper layers of the soil, it reaches ground water, which is water below the surface. The upper surface of this underground water is called the “water table”.
Why are percolation tanks bad for water conservation?
Percolation tanks should normally be constructed in a terrain with highly fractured and weathered rock for speedy recharge. Too high permeability may result in the percolated water escaping in the downstream as regenerated surface flow, hence it will defeat the purpose of water conservation.
When to use a percolation tank in India?
Thus, the percolation tank design should be made to maintain the largest possible storage capacity where water can percolate to ground water reservoir by January/February. Based on the soil texture and its capacity of water percolation, different practices are being employed in various states of India.
How is the inlet to a farm pond constructed?
The inlet channel to the farm pond are constructed in such a way that, all the surface runoff from the catchment area to concentrate at the channel and drain into the pond. The inlet is designed as chute spillway for conveying the runoff in to the pond.
How does depth of water affect the cost of pond lining?
Theoretically the volume of stored water per unit wetted area increases with the increase in depth of the water in ponds but at the same time increases the cost of pond lining. Thus optimization of various pond dimensions must be done for seepage reduction and cost of pond lining.
