CLW sanitation trucks cover municipal street cleaning and liquid-waste collection: road sweepers with twin brooms and 4-12 m3 debris boxes, sewage and fecal suction trucks with 4-16 m3 sealed tanks and Roots or liquid-ring pumps, combination jetting units, and garbage compactor bodies. The series serves city contracts, septic tank emptying, storm drain maintenance and industrial cleaning, with 4x2 light chassis for narrow streets and 6x4 units for trunk routes.
Sewage suction trucks on this page are vacuum tankers for septic tanks, pits, grease traps and drains, known as sewage truck, septic vacuum truck, jetter truck or vacuum tanker depending on the equipment fitted. A Roots blower draws air from the sealed 4-16 m3 tank and the pressure difference lifts sludge up the hose at roughly -0.08 MPa. Combination units add a high-pressure water pump and hose reel so the same visit can jet the line and suck out the debris; that is the machine most contractors mean by a vacuum jetting truck. Send the tank volume, suction depth and whether you need jetting. In US and UK usage the same body is sold as a septic truck, a liquid vac truck or a sewage lorry; the difference is tank size and whether a high-pressure jetter is fitted. A 4,000-8,000 L liquid vacuum truck with a 1,000 m3/h pump suits septic pumping rounds, while sewer jet trucks add 150-250 bar jetting for drain clearing.
A septic truck is a vacuum tanker that empties septic tanks, cesspits and grease traps. A Roots blower draws air from the sealed 4,000-20,000 L tank and the pressure difference lifts the sludge through the hose; combination units add a high-pressure jetter for the line. The same body is called a septic pump truck in the US and a sewage lorry or cesspit emptier in the UK.
Septic trucks discharge at an authorised wastewater treatment plant or a licensed receiving station; the load is never spread on land or discharged to a storm drain. Keep the disposal receipt for each trip - most local regulators require it. Reverse-flow discharge empties the tank at the station, and the time depends on tank volume and pump size.
Municipal sanitation is a fleet, not a single truck. CLW builds street sweepers with twin brooms and 4-12 m3 debris boxes, sewage suction trucks with 4-16 m3 sealed tanks and Roots or liquid-ring pumps, combination jetting units with 150-250 bar water, and compactor bodies for household waste.
A city contract usually needs sweepers for visible streets, suction units for drains and tanks, and compactors for household waste; buying one type for all three duties wastes crew time.
Define the duty before the body:
Send the route, daily volume and drain data with the destination port; CLW proposes a fleet mix and confirms tank, pump and body volumes before deposit.
Factory-direct FOB bands; a budget framework, not a quotation.
Compare sweep width, debris box volume, pump flow and vacuum, jetting pressure, tank steel and hose package. A low suction price often hides a smaller pump or a single-stage system that cannot hold vacuum at depth.
CLW builds sanitation bodies on MIIT-approved chassis in an ISO-certified factory. Pumps, sweepers and jetting systems are run-tested before shipment, and test records are supplied with the export documents: certificate of origin, invoice, packing list, bill of lading and inspection report on request.
Lead time is typically 20-35 working days for standard sweepers and suction trucks after deposit, and 30-45 working days for combination jetting and stainless bodies. Small 4x2 units ship in a 40FT container or on a flat rack; 6x4 units move by RoRo. Loading photos, lifting points and blocking instructions are provided before departure.
Sweeper and suction maintenance is dominated by the pump and the tank. Check the vacuum pump oil, belt and filter on schedule, keep the tank relief valve and vacuum gauge working, and inspect hoses and quick couplings for cracks before each shift. A falling vacuum usually means a leaking hose, a worn pump or a blocked filter.
For jetting units, test the pressure relief and lance trigger before use, never point the lance at people, and keep the water tank strainer clean. Wash the debris box and tank at the end of the shift and drain at the designated point. CLW supplies pump seals, hoses, nozzles, broom bristles and the body drawing with each truck.
