Waste management company CSG has invested almost £1m in new equipment including four specially built tankers. 

CSG has purchased two high performance rigid vacuum tankers and a long-distance articulated liquid ring tanker, along with a KOKS CycloVac HVAM (pictured)), costing more than £930,000 in total. 

The company operates the largest independent fleet of specialist waste management vehicles in the UK, providing domestic and industrial waste collection, recovery and processing services from 27 sites. 

The privately-owned company – which posted a £100m turnover for the first time in its most recent accounts - employs more than 600 people nationally, supporting a national network of waste treatment and recovery centres.

CSG said the new tankers will improve its capabilities in a number of areas, including helping customers with dense and hard to remove sludge, accessing areas on site that are difficult to reach and reducing time on site. 

Mark Hague, CSG technical sales manager, commented: “We are delighted to add this new equipment to our inventory, which will benefit our customers in terms of improved service and the business through cost efficiencies. 

“A standard liquid artic or rigid tanker has a 360 cubic feet per minute (CFM) pump but, in more awkward jobs where sludge is solidified or at a deeper level, these can lose suction power as soon as you start loading. 

“Many vehicles in our fleet are now fitted with higher performance pumps which cope better with sludges from interceptors and they also suck up the load faster, but they are not designed to run all day and sometimes will begin to overheat. This is why we’ve invested in these new, more powerful, specially built tankers. CSG has enjoyed an extraordinarily successful year and it’s fantastic to see continued investment in our operations.” 

CSG’s new high performance rigid vacuum tankers have capacities of 3,000 gallons and 4,000 gallons and can suck up to 1,000 CFM and both have a powerful jetter and turbo jet nozzle, usually used for cleaning pipework, tanks and pits where silt and other debris are causing problems for a drainage system. They are up to 2.8 times more powerful than a standard tanker, making them more fuel efficient and capable of tackling all waste types. 

The tankers will be used for petrol station forecourt cleaning, drain cleaning, at water treatment works and for food waste and infrastructure maintenance cleaning. They are also ideal for silt removal at large commercial sites and water treatment works. 

The long-distance articulated liquid ring tanker operates at 2,010 CFM. It has a 26,000 litre capacity and has a high power jetter for cleaning. nA standard tanker runs out of suction at around eight metres for water and five or six metres for sludge. The long-distance articulated liquid ring tanker extends to around 30 metres for sludges and even longer over flat surfaces. 

The new tanker is ideal for the quick loading of heavier sludges from deep chambers and for difficult to access locations where tankers cannot get close to the operational area - such as military and transport ships and railway networks. 

CSG’s KOKS Cyclovac HVAM (Disab) has a sizeable suction capability of 8,000 CFM. The tanker creates a massive movement of air into a vortex in the pipework, suspending the waste materials on a swirling air cushion, conveying it along the pipework into the tank. It will suck up a normal tanker’s worth of air in 7.5 seconds.

It has a capacity of 12,000 litres and is designed to run all day long. Its uses include assisting heavy construction work and flood control, cleaning silt ponds and lagoons and it can also be used to support other heavy jetting equipment.

Hague added: “The ability to remove sludge more quickly and efficiently from far greater depths and distances is key, but the advantages certainly don’t end there.The new trucks have lower emission engines, making them greener and more cost effective, while fewer hours on site will ultimately mean cost savings for customers.”
