Irrigation?

Drip irrigation, also known as micro or low flow irrigation, stands out as an innovative, ei-

cient, and eco-friendly watering system. This method precisely supplies water and nutrients

directly to the plant root zone through point-source emitters, driplines, micro-sprayers, and

other low-volume emission devices. By maintaining optimal soil moisture levels and balanc-

ing water and air, drip irrigation fosters healthier plants, reduces water loss from evaporation,

runo, and wind, and enhances growth and yields while minimizing weed growth, pests, and

disease. Ultimately, this approach conserves water, a valuable natural resource.

For optimal system performance and longevity, an eicient design is crucial. Begin by creating

a detailed drawing of the garden or site, illustrating the landscape layout, plant types, sizes,

and soil characteristics. Consider hydraulic factors, including water source location and type,

maximum volume, system flow rate, and static water pressure. Anticipate future additions to

the landscape by ensuring the design has approximately 20-30% extra water capacity.

Unlike other forms of irrigation, such as sprinkler

systems, drip irrigation system eiciency can

reach 90% and higher in delivering water directly

to the plants root zone.

What is Drip Irrigation? Drip irrigation, also known as micro or low flow irrigation, stands out as an innovative, efficient, and eco-friendly watering system. This method precisely supplies water and nutrients directly to the plant root zone through point-source emitters, driplines, micro-sprayers, and other low-volume emission devices.

Seamless Drip System Connections: Adhering to local codes, certain water districts may require a backflow preventer or anti-siphon device. The recommended backflow device prevents contaminated water from re-entering the water supply. If using an atmospheric vacuum breaker, install it on the hose bib (hose thread) at the head assembly’s start. For those incorporating a hose end timer, place the backflow device downstream to meet requirements and prevent device stress.

Water source: Key Considerations for Gravity Feed Systems 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. Considerations such as the total flow rate of the emission devices and the available pressure persist across different drip system variations.

The Vital Role of Emission Devices in Targeted Plant Watering Emission devices, such as drip emitters, dripline, micro sprinklers, or micro sprayers, serve as the backbone of drip systems, ensuring precise water delivery to plants. The connection process involves punching a hole into the poly tubing using a dedicated punch tool. Drip emitters provide a range of installation options, allowing them to be directly placed into the poly drip tubing or extended with a ¼ in. barb and ¼ in. micro-tubing.

Soil types and the right drip emitters WATERING WITH DRIPPERS Type of plant Soil characteristics, density, and texture play a crucial role in shaping the “wetting pattern” as water moves through the soil. In drip irrigation, water is applied gradually to the plant root, either through a single point source drip emitter or along the line using a drip line. The soil type guides the selection of the most suitable drip emitter flow rate and spacing.
