Waterwise, the UK's leading independent organisation on water efficiency and sustainable development, has just published its own White Paper, setting out proposals for the coalition government to help meet the challenges of climate change through wasting less water.Within the document, the important issues affecting the plumbing industry and all those who are now thinking of training to be a plumber, relate to green energy retrofitting schemes, appliance replacement and water meter installation.Strategic proposals cover climate change, adaptation and resource efficiency, the low carbon and green economy over the five years from 2010 to 2015.The proposals pinpoint for the coalition government, the need to place water efficiency at the heart of measures it is already taking to rise to these challenges, such as energy retrofitting schemes for homes, to ensure their maximum impact.Key proposals include :-Provision of services such as water efficiency to its consumers on a large scale, rather than just water supply.-Water efficiency included in the Green Deal energy efficiency retrofitting scheme.-Showers to be included in social housing refurbishment and new build-A toilet scrappage scheme to help householders trade in the one million toilets in England which flush at 13 litres for toiletswhich use a third of that water.-A water meter in every home by 2020 - supported by measures to protect vulnerable groups-Community-scale water provision and joint retrofitting programmes for energy, water and waste.The theme of the reports once more reinforces the important role a plumber will play in assessing green energy, specifying efficient solar water heating systems and heat pumps.Students enrolling on the established Plumbing NVQ 6129 level 2 course will learn the underpinning principles - and can choose to study the plumbing theory at home, before beginning the practical training. Once assessed and verified, progress on to NVQ level 3 is the next step, and qualification which allows further knowledge learning, e.g. Gas training or the different green energy courses that are now being offered in major approved and accredited training centres like South East England's AbleSkills.
