Lavatory and Water Service Trucks (EWT / ELT / ESL series)
IATA AHM-compliant lavatory and potable water service vehicles in towed-cart and self-propelled truck configurations for full aircraft servicing cycles.
Ersel's EWT/ELT/ESL series covers the two distinct fluid-servicing disciplines required at every aircraft turnaround: potable water replenishment (EWT series) and lavatory waste removal with rinsing water refill (ELT/ESL series). All models are manufactured in conformity with IATA Airport Handling Manual (AHM) standards, which govern tank construction, connection fittings, overflow protection, and hygiene separation between waste and clean-water circuits. The EWT-2500 is the primary self-propelled potable water truck, carrying 2,500 litres and extending a service platform to 3,000 mm to reach the water service panel on aircraft requiring an elevated connection. A smaller towed version, the EWT-1200 (1,200 L), suits regional or turnaround-only operations where less volume is needed per cycle; it accepts electric or hydraulic pump configurations and an optional pedestrian walking kit for ramp-only access. Both EWT models are available with tank heat insulation and a tank heater, a practical necessity in northern European winters and — conversely — relevant in GCC summer conditions where stagnant water in un-insulated tanks can exceed safe potable-water temperature thresholds. The ELT-2000 is the standard self-propelled lavatory truck, combining a 2,000-litre waste tank with a 1,000-litre rinsing water tank. The ESL-2000 is the electric-motor variant of the same platform, offering a zero-emission servicing option for operators under apron electrification commitments. Both lav trucks raise a service platform to 3,000 mm and include a vacuum system option for high-pressure waste extraction from aircraft with closed-circuit lav systems. For handlers servicing a mixed fleet of narrow- and wide-body aircraft, a 3.0 m maximum platform height covers the lavatory service port on A320/B737 class aircraft; wide-body servicing typically requires a higher-reach dedicated unit.

Use cases.
- ›Potable water replenishment for narrow-body aircraft on short-haul turnarounds (EWT-1200 towed or EWT-2500 self-propelled)
- ›Lavatory waste extraction and rinsing at narrow-body and regional aircraft stands (ELT/ESL-2000)
- ›Zero-emission lav servicing under apron electrification programmes (ESL-2000 electric variant)
- ›Cold-climate deployments requiring heated and insulated tanks to maintain potable-water temperature and prevent waste-line freeze
- ›GCC hub servicing where high ambient temperatures require insulated water tanks to keep potable water within safe storage temperature bands
