Professional Public Water System Installation Checklist

Why Professional Installation is Critical for Railway Stations

✔ Ensures 24/7 operation - Prevents water service disruptions for travelers

✔ Maintains water safety - Complies with public health regulations

✔ Reduces maintenance costs - Proper installation prevents 65% of common issues

✔ Extends equipment life - Correct setup adds 3-5 years to system lifespan

Industry Insight: Railway station water systems must handle peak usage of 500-1000+ people per hour during train arrivals

6 Professional Installation Steps

1. Site Preparation & Equipment Positioning

 • Location requirements: Dry, ventilated area with drainage

 • Space needs: Minimum 3m×3m for 2-ton system

 • Foundation: Level concrete base with drainage slope

 • Access: 50cm clearance around equipment for maintenance

2. Filtration Media Installation

 • Quartz sand: 0.5-1.2mm grade, layered by size

 • Activated carbon: Coconut shell carbon, iodine value >1000

 • Softening resin: Food-grade polystyrene, 30-40% crosslinking

 • Installation order: Coarse → Fine → Carbon → Resin

3. Plumbing Connection System

Station Water Supply --> Pre-filter Assembly --> Multi-media Filter --> Activated Carbon Filter

--> Water Softener --> RO Membrane Housing --> Pure Water Tank --> Station Dispensing Points

4. Electrical & Control System Wiring

 • Power requirements: 380V/50Hz for 2-ton systems

 • Grounding: ≤4Ω resistance, separate grounding rod

 • Protection: IP54 waterproof electrical boxes

 • Automation: PLC control with pressure sensors

5. Pretreatment System Commissioning

 • Backwash procedure: 30 minutes per filter

 • Flow rate setting: 15-20m/h per square meter

 • Pressure test: 1.5× operating pressure for 2 hours

 • Leak check: All connections with pressure applied

6. RO Membrane Startup & Calibration

 • Initial flush: 30-60 minutes at low pressure

 • Pressure adjustment: 1.0-1.2 MPa operating pressure

 • Recovery rate: Set to 65-75% based on water quality

 • Automatic cycle: Program flush sequences

Technical Specifications

5 Safety Critical Checks

✅ Structural integrity - Anchor bolts secured to foundation

✅ Electrical safety - Ground resistance <4 ohms

✅ Pressure testing - All pipes at 1.5× operating pressure

✅ Water quality test - TDS <20ppm after installation

✅ Emergency stops - Clearly marked and functional

Pro Tip: Install bypass valves to allow maintenance without shutting down entire water supply

Maintenance Protocol

 • Daily: Pressure differential checks across filters

 • Weekly: SDI testing and chemical dosing calibration

 • Monthly: Membrane performance normalization

 • Quarterly: Full sanitization and parts inspection

 • Annually: Membrane replacement and full system overhaul
