The City Government of Puerto Princesa required a heavy-duty, multifunctional municipal vehicle capable of handling urban drainage system maintenance, disaster relief, septic tank cleaning, and high-pressure sewer line jetting.

• Right-Hand Drive (RHD) / Left-Hand Drive (LHD) chassis configured to local Philippine road transport compliance.
• Combined dual-function design: high-vacuum fecal/sewage suction system alongside a high-pressure water jetting pump.
• Official municipal branding: Custom CDRRMO and Puerto Princesa City government logos, bilingual operational safety decals, and high-visibility LED warning light bars.

1. Define Your Capacity & Work Requirements: Determine the necessary ratio between the sewage suction chamber and clean water compartment depending on whether your operations focus primarily on septic desludging or pipe jetting.
2. Select Chassis & Drive Configuration: Choose 4x2 (6-8 CBM) for narrow urban streets or 6x4 (12-15 CBM) for large municipal engineering projects and heavy disaster response duties.
3. Choose the Right Vacuum Pump:
   • Rotary Vane Pumps: Best for standard liquid waste and septic hauling.
   • Water-Ring Vacuum Pumps: Ideal for continuous heavy-duty operation, thick sludge, and hot tropical environments like the Philippines.
4. Inspect Local Compliance: Verify engine emission standards (Euro 2/Euro 5), steering position (LHD vs. RHD), and road axle load regulations prior to shipment.
5. Shipping & Delivery: Confirm delivery arrangements (Ro-Ro or Flat Rack container) to major ports in the Philippines (e.g., Manila, Subic, or direct feeder to Puerto Princesa Port).

• Inspect engine oil, coolant, hydraulic fluid, and vacuum pump oil levels before operation.
• Check primary and secondary shut-off valves to ensure no sewage enters the vacuum pump.
• Clear water trap filters and drain accumulated moisture from air reservoirs.

• Grease all hydraulic cylinder pivot points, rear door hinges, and the PTO drive line.
• Inspect high-pressure jetting hoses for abrasion, cracks, or fitting leaks.
• Clean the suction strainer and check nozzle orifices for debris blockages.

• Replace vacuum pump filter elements and hydraulic system suction/return filters.
• Check the high-pressure water pump oil condition; change oil after the first 50 operating hours, then every 300 hours.
• Flush clean water tanks to remove silt buildup and check internal anti-corrosion linings.
