Drip Irrigation System - The project requires the setup of two independent systems: • Site 1: Installation for 500 beds. • Site 2: Installation for 100 beds. • Scope of Work and Materials Required Your quote must cover all labor, materials, and installation for the following requirements: 1. Bed Irrigation Setup (for all 600 beds): • Bed Dimensions: 10 meters (length) x 0.15 meters (width) x 1.20 meters (height). • Drip Lines: Four parallel drip line per bed, which may extend in length to consecutive beds. Emitter (dripper) spacing of drip lines should be 6 inch • Fittings: All necessary 16mm pipes, O-rings, take-ups, and 16mm valves connecting to the main line. 2. Underground Main Supply Line: • Pipe: 75mm diameter, 4-gauge PVC pipe. • Installation: Pipe must be installed 1 meter below ground level. • Total Length: Approximately 550 meters of underground piping across both sites • Water Source Setup: Supply and installation of a 5000-liter water tank. • Pumping: Supply and installation of a 5 HP motor. • Filtration & Fertigation: Installation of a Screen Filter, a Sand Filter, and a Venturi injector system for fertilizer application. 4. Site 2 Specific Equipment (for 100 beds location): • Water Source Setup: Supply and installation of a 1000-liter water tank. • Pumping: Supply and installation of a 3 HP motor. • Filtration & Fertigation: Installation of a Screen Filter, a Sand Filter, and a Venturi injector system for fertilizer application. • Valves to be provided as per requirement for sectorwise irrigation
