Overview of innovation

An irrigation sprinkler riser technology which comprises of a flexible tubular body which is installed to join from the lateral water supply pipe to the sprinkler head, allowing adjustable positioning of the sprinkler at various angles or directions by means of an adjustable knob. The body of the flexible sprinkler riser is developed using tubular material where an adjustable knob allows for the rising or collapsing of the riser depending on the presence or cut-off of water supply. The ability of the riser to collapse when not in use furthermore provides protection of the sprinkler from mechanical damages that may occur if rigid sprinklers constantly remain in an upright position. The irrigation sprinkler riser technology, therefore, offers a simple and adjustable pipe for efficient and cost-effective irrigation.

Irrigation failures and damage are a result of many factors, including inefficient irrigation systems, the age of the landscape, proximity to trees, rodent activity and vandalism. Although other sprinkler systems have been introduced to support the durability of irrigation systems, many systems still suffer from wear and tear needing constant replacements, making them expensive to maintain.  The Flexible Sprinkler Riser technology aims to improve the lifespan of irrigation sprinklers by providing a cost-effective flexible body riser that ensures risers are protected from mechanical damage through the collapsible tubular body and are easily adjustable at various angles allowing optimum irrigation with changes in water pressure.
