Frequently Asked Questions
How much does it cost to put in a pivot irrigation system?
There are many important factors, but here are three main things to consider: Initial Investment Cost – Pivots cost $600/acre* less, and retain their value.
How much does a irrigation system cost in South Africa?
According to the ARC Agricultural Engineering Institute, the capital cost of a quick-coupling movable pipe sprinkler irrigation system is between R10 000/ha and R12 000/ha, and between R11 000/ha and R13 000/ ha for a dragline irrigation system, depending on sprinkler spacing, application rate and cycle time.
How many hectares does a Centre pivot cover?
Land area: A typical centre pivot system has a span of 300 to 400 metres long and irrigates 28 to 50 ha. However, they can be as short as a single-span 35 metre unit or as long as 800 metres with 18 to 20 towers irrigating approximately 200 ha.
How much power does a pivot use?
Pivots use both 120 and 480 volts of alternating current (VAC) to operate. 120 VAC is used as the control circuit, powering the safety circuit, the forward and reverse movement of the pivot, and, more precisely, the movement of the Last Regular Drive Unit (LRDU).
How many acres does a pivot irrigate?
How many acres can you cover with a pivot? 400m long pivots are the most common length. With an end gun operating a 400m pivot could effectively irrigate up to 140 acres under good wind conditions. A 500m pivot can cover up to 220 acres in low wind conditions.
How much does a 10 acre pivot cost?
“A 10-acre system sells for about $7,000. That cost won’t compete with wheel lines but our maintenance costs are much less because cattle won’t bother it.”
How much does a 40 acre pivot cost?
40 acre Center Pivot System Example. Standard 40 acre system with end gun, installed at a cost of $38,000 with a well and power source cost of $30,000.
How long do irrigation pivots last?
Fecht notes most irrigators in the area maintain pivots for about 18 to 20 years before replacing them — although pivots usually last 30 to 35 years before being sold for scrap.
How much does it cost to irrigate 1 acre?
Irrigation system costs by type. A lawn irrigation system costs $500 to $10,000 per acre, depending on the type. An in-ground irrigation system for a 1/4-acre yard costs $2,000 to $4,500 on average. *Price includes materials and professional installation.
How much water does a pivot need?
This example shows the minimum water supply rate for a center pivot equipped with high pressure impact sprinklers should be approximately 772 gallons per minute (656/0.85). The minimum system flow rate for a center pivot with low pressure spray nozzles at truss rod height would be 690 gpm (656/0.95).
Why do farmers use pivots?
They allow farmers to irrigate crops with a fraction of the labor required by traditional methods and do it with closer control of when and how much water they applied. As a result, center pivots can efficiently water an entire field and meet the crop’s irrigation needs while using less water.
How far apart are pivot towers?
The distance between towers is called a span. The length of the span can vary between 130 and 200 feet. The typical pipe on the pivot has an outside diameter of 65/8 inches with a wall thickness of 0.109 inches. The pipe and the towers are typically galvanized to prevent corrosion.
How fast does an irrigation pivot move?
Typical periods for a full rotation include three days; while other sources have the outer edge of the structure moving at 2 to 3 m (6.6 to 9.8 ft) per minute, which would equate to 14 to 21 hours for one full rotation of a 400-meter-radius (1⁄4 mi) system.
