PRESERVE HISTORIC CIVIC SPACES CHEMICAL-FREE.
High-temperature steam and vacuum capture systems for town centres, pedestrian plazas, chewing gum, and graffiti removal.
What Is Being Cleaned
Town centre management teams, local authorities, and highway agencies maintain public footpaths, bus shelters, monuments, subways, and street furniture. Operations require removing millions of chewing gum deposits, racist or offensive graffiti, food grease outside takeaways, and urban pigeon guano.
Site & Technical Constraints
High-pressure water washing erodes historic stone mortar joints and creates hazardous water pools in active shopping precincts. Harsh chemical solvents risk polluting stormwater drains. Municipalities require low-volume, high-heat wet steam (150°C+) with WRAS Category 5 water protection.
THE RECOMMENDED TRAILER ARCHITECTURE.
A compact single-axle 1,500kg or tandem 2,700kg open/enclosed rig featuring the Alkota 325-CSH industrial steam generator. Includes a WRAS Category 5 air gap break tank, 500L–1,000L water tank, and an Alkota VACGD vacuum recovery system to suction slurry instantly.
155°C Saturated Steam Power
Thermal breakdown dissolves chewing gum in under 3 seconds and liquefies graffiti paint without chemicals or abrasive sandblasting.
WRAS Category 5 Backflow Protection
Mandatory air gap break tank prevents any possibility of contaminated wastewater syphoning back into public drinking water hydrants.
Low Water Consumption (11.4 LPM)
Thermal steam uses significantly less water than standard washers, reducing wastewater volume in busy pedestrian high streets.
Instant Vacuum Recovery
VACGD suction picks up wastewater immediately behind the lance, leaving pedestrian footways dry and safe to walk on within seconds.

Municipal & Public Realm Sanitation Engineering FAQs
Why is steam superior to cold high-pressure water for chewing gum removal?
Cold water pressure washers rely on raw blast force that can damage the stone aggregate and gouge jointing sand. 155°C wet steam melts the rubber polymer bonds in chewing gum, cleanly vaporising the deposit with zero surface harm.
What is a WRAS Category 5 break tank and why is it needed?
UK Water Supply Regulations classify industrial washing equipment connected to commercial hydrants as Category 5 fluid risk. An approved mechanical air-gap break tank physically separates mains drinking water from the trailer plumbing.
