Why Drip Irrigation Could Be Best For You
This article explains the benefits of a drip watering system and how it works. Drip Irrigation – any watering system that delivers a slow-moving supply of water at a gradual rate directly to the soil. Referred to as micro-irrigation or trickle irrigation. The systems consist of a network of pipes, tubing valves, and emitters.
One of the most water and energy-efficient methods of irrigating.
Drip irrigation offers several great benefits. This includes conserving water, and energy, saving money on those bills, increasing plant health, and design flexibility. The tubing can be laid out to conform to any oddly-shaped landscape layouts. It can also extend to hanging planters, or extend down rows in a vegetable garden. Other applications include flowerbeds, ground cover, and street medians.
Drip Irrigation, Micro-Irrigation, And Sprinkler Systems
Although frequently used interchangeably, some would argue that drip irrigation and micro-irrigation are two distinctly different things.
Drip irrigation – all low-pressure, drip methods of delivering water to the soil using either porous pipe or emitter tubes.
Micro-irrigation – all watering systems that use low-pressure sprays or misters.
How you refer to these forms of irrigation is not really relevant. It is important to be familiar with the options and benefits of both. That said, it is important not to confuse traditional sprinkler systems with micro-irrigation.
Traditional sprinkler systems, whether they use an impact, stationary, or rotary spray head, differ from micro-irrigation. These systems operate at much higher pressures. They deliver large quantities of water for a fixed amount of time. They work with long intervals between watering times.
Although micro-irrigation uses spray heads, they operate at considerably lower pressures. Micro-irrigation delivers much smaller quantities of water at frequent intervals.

Other Drip Irrigation Benefits Include Water Conservation
Typical sprinkler systems are, on average, about 75% water efficient, while drip irrigation systems have 90% or higher water efficiency. This is due to several key design differences.
High-pressure sprays deliver too much water too quickly. It cannot be absorbed by the soil and is prone to wind dispersal. The water can’t be absorbed, it either puddles, which can be unhealthy for plants, or it runs off and is wasted.
The slow delivery rate of drip irrigation allows the soil to absorb the water laterally, and maintain a uniform moisture level. The direct delivery of water to the soil also removes the risk of wind dispersal.
The increasing popularity of conservation, environmental friendliness, and the “green” movement have made drip irrigation a trendy choice, but it is a sound option for increasing plant health and saving money, as well. Drip systems are easy to design and install. They don’t require any trench digging and the above-ground tubing can be conformed to a variety of landscapes. This makes them a great option for avid do-it-yourselfers, and installing the system yourself will save a considerable amount of money.
Overall, drip irrigation is a great option, whether your goal is environmental and economic conservation, plant health, design simplicity, or all of the above.
