Micro Irrigation System Included The Installation Of PVC Pipe, Fittings, Risers, Polyethylene Tubing And Rain Bird Micro-Quick Jets For Farm Outside Scottsdale, AZ

The project was installed on an Indian farm. The crops to be irrigated included 320 acres of citrus on a 20x22 ft spacing, and 769 acres of pecans on a 30x30 ft spacing.

Rain for Rent's part in the project included the installation of PVC pipe, fittings, risers, polyethelene tubing and Rain Bird Micro-Quick jets. We surveyed and flagged all tree locations as well.

The bid also required the presence of a full-time site engineer during all phases of installation and testing. A member of Bakersfield's engineering group readily volunteered to take on the project and has served not only as engineer, but as foreman to coordinate the installation phase.

The terrain around the project was rugged, with beautiful saguaro cacti and panoramic views. Most of the 30 miles of trenching had been fairly easy going, but there was rough ground with caliche (a form of natural concrete) to deal with. The customer removed all surface vegetation and large rocks. The resulting topography was rolling hills with some natural drainage channels in place. Another challenge was surveying the rough terrain and flagging trees, which was difficult in some areas due to the lack of soil in which to install the flags.

Over 335 miles of polyethelene laterals were slip-plowed under the soil to a depth of approximately 12 inches. Tube was shanked in using a plow, pulled by a tractor.

Trenching was carried out by the use of three wheel trenchers and one excavator. Some "bedding" of PVC pipe with sand has been required in trenches through rocky spoils.

During the various phases of completion, Rain for Rent added a four-tank portable water media filter with a 1200 GPM booster pump on site to provide water for flushing and pressure testing lines.
