Residential Irrigation Spray Nozzles

1. Residential Irrigation Spray Nozzles

2. An innovative patent pending technology in the field of Residential Lawn Irrigation Market Sovi Square patent pending products are based on a simple yet innovative Pop-Up Spray Heads & Nozzles that has an AdjustableRectangle/​Square 0° to 360° to complement and is compatible to current standard adjustable circular Pop-Ups.

3. The current solutions • In many, if not most cases, the lawn garden of residential houses are Rectangle shape or combinations of Rectangle areas • In most cases the method of irrigation systems are Circular spray head pattern popup sprinkles • As a result we see a discrepancy between the irrigated area geometry and the irrigation system pattern, i.e. Rectangle Vs. Circle

4. The discrepancy causes: • Uneven water distribution • Waste of water • Dry patches or excess watering • Excessive use of sprinklers, components & ancillary equipment • Conclusion: Inefficient Irrigation • To prevent the Inefficiency Irrigation and allow 100% coverage, an overlapping guidelines for circle spray head sprinkles installation were developed during the years

5. Overlapping implications Water distribution with 6 circular sprinkles ~27% of the area has 4 watering sprinkles ~44% of the area has 3 watering sprinkles ~29% of the area has 2 watering sprinkles Main Conclusions: The area receives uneven water distribution Assuming that two (2) sprinkles overlapping per area is the minimum required, then around ~70% of the irrigated area receives overlapping irrigation

6. Sovi SquareTechnology Capability • The technology supports an adjustable 0° to 360° Square of 4x4, 6x6, 8x8 meters with 30 PSI, but not limited • The technology supports an adjustable 0° to 360° Rectangle of 4x6, 6x10 meters with 30 PSI, but not limited • The technology supports EST, CST, RCS, LCS, SST with one single model and also capable to tune the water distance

7. Circular Spray Heads Typical installation To achieve 100% coverage without dry patches, will require 30Circular Spray Heads and complex infrastructure to support them using the overlapping guidelines

8. Sovi Square Rectangular/Square Spray Heads installation To achieve 100% coverage without dry patches, will require about ~16 Sovi Square Spray Heads and simplified infrastructure to support them.

9. Sovi Squaresolution: Sovi Square solution provides 100% coverage and better uniformity with less sprinklers leading to a lower cost over all package, i.e. infrastructure and water saving to our customers with significant ecology contribution, i.e. Green product. • Breakthrough simple design - up to 3 parts • Interchangeable to current Pop-Up systems • Simpler infrastructure installation • Material and labor ~30% saving • Water consumption ~25% saving • Has superior water distribution uniformity

10. Sovi SquareVision To install Sovi Square innovative Spray Head Nozzle in all major irrigation popup sprinkler systems and contribute to Saving overall Cost of Ownership to our customers, i.e. manufactures, distributors and end users worldwide.
