20 | AUGUST 2018 | WWT | www.wwtonline.co.uk The Works: air quality • PUMPS, ENGINES AND EQUIPMENT E quipment manufacturers serving the water industry – especially those that use diesel engines such as mobile pumping and drainage equipment – have been preparing for some time to make their products fit for the latest round of emissions regulations. Stage V of the new EU emissions regulations for non-road mobile machinery (NRMM) were passed in 2016 and come into effect in 2019. The regulations are categorised based on the engine power rating and ignition type, with each category given limits for the output of carbon monoxide, nitrogen oxides and particulate matter. These standards are applicable to diesel engines from 0 to 56 kW and to all types of engines above 56 kW, therefore bringing in much more stringent regulations for a wider scope of engines. One of the challenges facing the manufacturing industry will be to build equipment that is the same size and weight and, perhaps most importantly, price as their existing equipment. Engine size and weight will increase with the requirement to fit engines with selective catalytic reduction technology and diesel particulate filters. For contractors this may impact on the size of vehicle they need to transport equipment and the volume of fuel they use on a daily basis. Engine emissions compliance can also be achieved by retrofitting engines with approved abatement technology. The retrofitting of exhaust post-treatment devices is a common procedure for heavy- duty off-road engines, such as generators or diggers, but generally not possible for compact machines used for tasks such as drain jetting. It's not all bad news for buyers though. unveil a range newly adapted equipment for the European market. It has previously invested in PTO (Power Take-off) technology that uses power from the vehicle engine to operate the pumps used in its jet/vac combination units. Marc Soethout, Rioned's Chief of New Product Design, says the company is focussed on producing cleaner alternatives: "I'm a firm believer in being environmentally-conscious, especially as our machinery is ošen used in urban areas. Although developing effective solutions presents Rioned with numerous challenges, I fully support the goal that we're working towards." He explains that customers can expect to pay more for new equipment as the clean engines are more expensive, but says the biggest impact of new regulations will be felt by the machinery manufacturers who'll have to adapt their machinery: ''Our engine manufacturer is working hard to develop new engines. Rioned machines are built very compactly, and don't have the capacity for these engines, which tend to be much larger. The machinery needs to be re-designed. "All machinery with a capacity above 19kW will be fitted with a new engine. In other words, all the high-pressure machinery apart from the HD30, MiniJet, FlexJet and AquaJet. The air-cooled petrol engines that are widely used at Rioned meet the new norms, but all other machinery will all need to be adapted prior to 2020." "In the long term," he says, "those most affected by the new standards will be us: we'll all be breathing air that's a little bit cleaner." Caption The regulations include a transition scheme that takes into account the time difference between the date of engine manufacture and the time it is on the market before being sold. This means contractors may be able to purchase existing equipment for a limited period ašer the regulations come into effect, though the ongoing spike in demand will probably lead to limited availability. Drain and sewer cleaning equipment manufacturer Rioned has spent years preparing for the new EU regulations and last year introduced the fully compliant ProfiJet T4 with a v48kW diesel engine. The company also produce machinery fitted with petrol engines including the CityJet Petrol that is available with a 37kW petrol engine (with a catalyst). In the build-up to 2019 Rioned plan to
