waste tankers to its rental fleet in response to the water companies' increasing use of contract-hire vehicles for shifting large volumes of sludge and non-hazArdous waste.
Half the new purchases are Fruehauf semi-trailers; the rest are rigids, bodied mainly by Somerset-based Barvick Engineering with two by Thompson Carmichael.
The 26,0001it tanker trailers have Drum Mistral rotary blowers/exhausters with acoustically housed Perkins power units. They are built for operation at 38,40 or 44 tonnes GCW.
