A sprinkler system is a type of irrigation that pumps water into your garden or field and scatters it into the air, to fall onto your lawn or crops. What are the benefits of installing such a system? Natural The aim of a sprinkler system is to imitate nature as much as possible. Your plants expect water to fall as rain and to land evenly in droplets. This allows them to grow properly without becoming waterlogged or leaving parched patches where the water didn't reach.
