Pumping
The pump sets what the whole system can do. It is sized to the water the source can give and to the pressure the field needs, and runs on the grid, a generator or the sun.
- Borehole
- A submersible pump set below the water level, sized to what the borehole gives when it is tested.
- River or reservoir
- A surface pump drawing through a screened intake. A reservoir lets a slow source fill up between irrigations.
- Solar array
- Panels that run the pump in daylight, with no fuel to buy.
- Pump and gauge
- The pump that brings the water up to the pressure the system needs, with a gauge to check it.
- Power
- Grid, generator or solar, chosen with the running hours and the fuel cost in mind.
- Drip, sprinkler and pivot systems
- Boreholes, rivers and reservoirs
- Farms without grid power
What the design looks at
- What the source can give, from a pumping test where there is one.
- The total head: the lift, the losses in the pipes and the pressure needed at the emitters or sprinklers.
- The flow of the largest block watered at one time.
- The hours the pump can run each day.
- The power available, and what it costs to run.
- A pump chosen to work near its best efficiency point.
We size and supply the pump and its power supply as part of the irrigation system, install it, then start it up and check it.
Drip irrigation
For row crops, orchards and plantations, with the water and the nutrients delivered at the roots.
Sprinklers and rain guns
For field crops and pasture, where the whole surface needs water.
Centre pivot
For large, regular fields, with sprinklers and a control panel matched to the crop.
Filtration and fertigation
Filters that protect the emitters, and dosing that feeds the crop through the water.
Valves and automation
Automatic valves and controllers, so each block gets its water at the right time.
