Farm Pond in Kenya for gravity feed drip irrigation
Comsider the question of how to water your garden automatically using gravity feed drip irrigation from a farm pond or rainwater tank. If your tank is at ground level, the water pressure may be inadequate when the tank is almost empty. The conventional solution to the problem is to use a pump. However, a suitable pump may be expensive and there will be ongoing costs for power. A less expensive approach is to use a small header tank and to use a small inexpensive solar-powered transfer pump to slowly refill the header tank between irrigation events.
If you use a conventional programmed irrigation controller with gravity feed irrigation, the dripper discharge will vary as the water level in the header tank changes. This is not the case with measured irrigation
Automatic gravity feed drip irrigation from a farm pond or a rainwater tank does not require access to mains power or batteries. Details are available for two unpowered controllers, namely, the Unpowered Terracotta Irrigation Controller and the Unpowered Pitcher Drip Irrigation Controller.

Choosing between the Unpowered Terracotta Irrigation Controller (UTIC) and the Unpowered Pitcher Drip Irrigation Controller (UPDIC)
UTIC: Plants may have different irrigation requirements.
UPDIC: All plants should have the same requirement.
UTIC: Adjust the wate usage rate by adjusting the control dripper
UPDIC: The water usage rate is controlled by the demand from the plants. The discharge from each dripper during an irrigation event is the same as the on-demand discharge from the subsurface clay pot since the previous irrigation event
UTIC: Adjust the interval between irrigation events by adjusting the float.
UPDIC: The interval between irrigation events may be less than a day.
UTIC: As the water needed by your plants changes as the plants grow, the discharge from each dripper during the irrigation event needs to be adjusted manually by adjusting the control dripper.
UPDIC: As the water needed by your plants changes as the plants grow, the discharge from each dripper during the irrigation event adjusts automatically.
