An expanded external display area at WJA Trade Show 2025 has been fully booked by exhibitors – creating a exciting opportunity for visitors to see the UK’s newest and most advanced water jetting equipment.
Brand new high pressure pump systems, industry-leading jet vac tankers and the world’s most advanced jetting robots are among the specialist machines that will be on show on 11th September.
The external display area – double the size of the space available at the inaugural event last year – is expected to be one of the big draws at WJA Trade Show 2025 at StoneX Stadium, North London.
Opportunity for closer look
“We’re delighted the external stands have proved so popular, with every space taken. In fact, we found room for a 10th exhibitor, but we’re now definitely full!
“The drainage and wastewater industry will be particularly well represented, with Bucher Municipal, Rioned, and AQ Rent each showing off their latest compact jet vac tankers.
“There will be plenty of large equipment destined for other industrial sectors on display. It’s going to be a great opportunity for contractors to get a close look at the very latest water jetting technology.”
WJA Trade Show 2025 promises to deliver the world of water jetting in one place, with event four sponsors – Veolia, TST Sweden, Drain Trader Magazine, and Howden Insurance
– WJA Director Leanne Smith
First chance to view new unit
Leading water jetting pump manufacturer Calder will be displaying their new MultiJet 340 – a 340 kW (455HP) water jetting powerhouse. The unit is available in diesel and electric drive configurations and can be supplied in skid or containerised formats.
Alongside the 340 will be Calder’s hugely popular MultiJet 200 trailer-mounted, Stage V compliant jetting unit.
The Worcester-based company will also be displaying water jetting accessories. These will include a Rotacar pipe cleaner, a Freelance tube cleaning machine and a Flexa-Jet chain manipulator.
“We’re very much looking forward to presenting these cutting-edge machines at both our external display and internal stand.
“Having this opportunity to show what Calder’s high-performance machines deliver for all sectors of the UK water jetting industry is an exciting prospect we didn’t want to miss.”
– Peter Quick, Business Development Manager at Calder

Safe maintenance systems on show

New exhibitor ETS Degassing will be displaying machines its teams uses to support the controlled removal and treatment of hazardous gases released during industrial shutdowns, tank cleaning, and maintenance operations.
