YOUR DRIP IRRIGATION GUIDE
DIG CORPORATION
Gravity fed low pressure system starting from a rain collection tank or storage barrel
Rain barrel: Y-Hose splitter, filter, pressure regulator, 1/2 in. drip tubing, stakes, shut-o valve,
compression fittings, non-pressure compensating drip emitters, hose-end closures.
Numerous methods can be employed to initiate and establish drip irrigation systems,
whether drawing water from a well or utilizing a barrel for gravity feed. Regardless of the
specific setup, the fundamental components of any drip system remain consistent. Consid-
erations such as the total flow rate of the emission devices and the available pressure persist
across dierent drip system variations.
When deciding between a pump and gravity feed for your drip system, essential factors
include the minimum operating pressure of the emission devices, total flow rates, and
water pressure. These aspects play a pivotal role in ensuring the system operates eiciently.
Notably, as the length of the laterals increases, the number of drip emitters used rises, and
the flow rate of the emitters goes up, the demand for pressure also intensifies. It is worth
noting that the sole dispensable component in this context is the pressure regulator.
For optimal performance in gravity flow systems, it is advisable to opt for non-pressure
compensating drip emitters and/or utilize ¼ in. dripline. This choice aligns with the specific
requirements of gravity-fed setups, contributing to the overall eectiveness of the drip irriga-
tion system.
