Sprinkler irrigation system Is used in DDA park sector -11

DDA Park, Sector -11, Dwarka

Sprinkler Irrigation is a method of applying irrigation water which is similar to rainfall. Water is distributed through a system of pipes usually by pumping. It is then sprayed into the air and irrigated entire soil surface through spray heads so that it breaks up into small water drops which fall to the ground.

Advantages of Sprinkler Irrigation System

This technique enables judicious utilization of even small water flows and permits efficient irrigation of undulated lands, and soils with shallow depths.

It saves 10to 16% land that is used in construction of channels and ridges in other methods.

Highly permeable as well as relatively less permeable soils can be easily irrigated by sprinkler method without any risk of run-off and erosion, inundation and seepage losses.

Fertilizers, pesticides and weedicides can be applied along with water spray, thus, saving extra labour.

Advantages Of Sprinkler Irrigation system

Disadvantages of Sprinkler Irrigation Method

High initial cost of equipments.

Operating costs are generally higher than irrigation by surface methods.

Winds disturb the sprinkler pattern giving uneven distribution of the irrigation water.

Sprinkling with water containing an appreciable amount of salts may result in bum or death of the plants.

Under certain climatic conditions diseases may be encouraged. The problem of fruit rotting in tomato and strawberry gets aggravated especially in moist soil condition.

Drip Irrigation system Is established in DDA Park, Sector -6

DDA Park, Sector -6, Dwarka

Drip System – Drip irrigation is the most water-efficient way to irrigate many different plantings. It is an ideal way to water in clay soils because the water is applied slowly, allowing the soil to absorb the water and avoid runoff. Drip devices use a fraction of the water that overhead spray devices use. “Point source” drip systems are comprised of drip tubing that is laid throughout a planting bed and feeds water directly to the base of the plants at a rate the soil can absorb without losing water to misting, overspray, or runoff.

Drip irrigation System

Advantages of Drip Irrigation

Water is used at maximum level.

As water is applied locally and leaching is reduced, fertilizer/nutrient  loss is minimized.

Weeds can not absorb water as no water is available for them.

Yield of crops are maximum.

Fertilizers can be used with high efficiency.

Weed are grown in less number.

Operational cost is low.

Advantages Of drip irrigation system

Disadvantages of Drip Irrigation

Expense specially initial cost is high.

The lifetime of the tubes used in drip irrigation can be shortened by the sun causing wastage.

May cause clogging if water is not filtered correctly.

Problems in moisture distribution.

Salinity problem.

Germination problem.

High skills are required.

Rotary Irrigation system is used In DDA park, Sector -10, Dwarka

Rotary Systems

This method of irrigation is best suited for larger areas, for the sprinklers can reach distances of up to 100 feet. The word “Rotary” is indicative of the mechanical driven sprinklers moving in a circular motion, hence reaching greater distances. This system waters a larger area with small amounts of water over a longer period of time.

Rotary irrigation System or Center Pivot irrigation

The center-pivot irrigation system is considered to be a highly efficient system which helps conserve water.

Center pivot irrigation typically uses less water compared to many surface irrigation  and furrow irrigation techniques

It reduces the expenditure of and conserves water. It also helps to reduce labor costs compared to some ground irrigation techniques, which are often more labor-intensive.

Advantages of rotary irrigation

It is now understood that groundwater level elevation decreases when the rate of extraction by irrigation exceeds the rate of recharge.

At some places, the water table was measured to drop more than five feet (1.5 m) per year at the time of maximum extraction.

In extreme cases, the deepening of wells was required to reach the steadily falling water table
