The Automation Kit for Farm Pond Irrigation is for smallholders with a farm pond and gravity feed drip irrigation from a header tank. Water is pumped automatically from the farm pond to the header tank and your small farm is irrigated automatically by an Unpowered Terracotta Irrigation Controller. You can leave your farm unattended for weeks on end, and so you can become involved in other activities away from the farm; for example, travelling to the market to sell your produce.
It is assumed that the bottom of the farm pond is no more than 4 metres lower than the irrigation drippers. The water supply pressure from the header tank should be at least 1 metre head.
As well as the User Manual, the kit includes the following four components:
- Waterproof pump controller with solar charge controller inside
- Double pump (two pumps connected in series) with an inlet filter, fittings to connect to 19 mm poly pipe, and 9 metres of waterproof electrical cable
- Float switch
- Unpowered Terracotta Irrigation Controller
The following items will be required to install the kit and may be purchased locally:
- 12V battery
- 20W solar panel
- 2-strand electrical cable
- wire connectors
The Unpowered Terracotta Irrigation Controller can supply water to approximately 500 non-pressure compensating (NPC) drippers on flat land (assuming that each dripper has a flow rate of 2 L/H at 100 kPa). If your farm requires more than 500 drippers, you can subdivide your farm into zones with up to 500 drippers per zone (each zone has a separate controller). The Unpowered Terracotta Irrigation Controller can be purchased separately from the Measured Irrigation website.
