1. Executive Summary & Design Basis 

This proposal outlines a modular, cost-effective, and scalable precision irrigation system, customdesigned for your 1,500-hectare coffee plantation. The design is based on the following parameters: 

 •Project Scale: 1,500 Hectares 

 •Planting Spacing: 3.6 meters x 0.5 meters (Row Spacing x Plant Spacing) 

 •Water Source: River 

 •Terrain: Predominantly Flat/Even 

 Our primary objective is to maximize coffee bean yield and quality through efficient, uniform irrigation  and fertigation management, while minimizing water consumption and operational costs. This will  contribute to a more sustainable and profitable coffee production system

2.Overall Irrigation Strategy: Modular Rotational Irrigation 

Given the significant scale of 1,500 hectares, we propose a "Zoned Control, Rotational Irrigation"  strategy. The entire project area will be divided into independent Irrigation Blocks, allowing for efficient  water resource management.  •Single Irrigation Block Size: Based on typical pump performance parameters (flow rate of 80  m³/h), we have determined that an optimal size for each irrigation block is approximately 1.2  hectares.

 •How it Works: The pumping station and head control unit will supply water to only one 1.2- hectare block at any given time. By using a system of valves, the system can sequentially  irrigate each block, enabling a single pumping system to effectively manage a large land area.  This approach significantly reduces initial capital investment.

3. Information Required & Next Steps 

In order to provide you with a final, precise system design and quotation, we require the following  information: 

•Site Coordinates or Layout Map: This is the most crucial step. Accurate site coordinates or a  detailed layout map will enable us to perform hydraulic calculations, optimize pipeline routing  and sizing, and generate a final equipment list and quotation.  

•Soil Type Confirmation: Please provide confirmation of the primary soil type (sandy, loam, or  clay) within the project area, as this will inform our selection of the optimal emitter flow rate.  

We are prepared to move forward with the next phase of this project upon receipt of the requested  site information. We are confident that this precision irrigation system will significantly enhance the  productivity, quality, and sustainability of your coffee production operations.
