Sounds like it's your highly officious local UK environment agency you should be getting a bit disillusioned with rather than the polluting effect of the method, which was discussed here a month or two ago and would seem to be more of a molehill than a mountain. Is it really worse than soapy residues etc from dishwasher, laundry detergents, bathwater? Aleks detailed the contents of the waste water (pretty innocuous) and said there's no need to be saintlier than the Pope. Keep 2nd and 3rd wash water for next-batch first wash; dilute first-wash water and offer it to your lawn - try a small patch first, but prolly neither lawn nor moles will mind, might even appreciate it. Nothing you don't find in fertiliser bags. You can find a helluva lot worse in fertiliser bags: 6.2 million pounds of lead compounds, 1.3 million pounds of chromium compounds, 233,000 pounds of cadmium compounds, 212,000 pounds of nickel compounds, 16,000 pounds of mercury compounds and 223 pounds of arsenic compounds (dioxins not measured) supplied in US fertilizer bags in 2000. Plenty of real problems with water pollution in the UK to be concerned about. "UK's polluted rivers named" - "WWF says the relevant government agencies do not have the money to monitor fresh water properly, and are often powerless to act even when they find problems." http://news.bbc.co.uk/hi/english/sci/tech/newsid_1285000/1285883.stm Should add this: "Aerosol Pollution Could Drain Earth's Water Cycle", San Diego, California, December 7, 2001 (ENS) -- Pollution may be seriously weakening the Earth's water cycle, reducing rainfall and threatening fresh water supplies. A new study by researchers at the Scripps Institution of Oceanography suggests that tiny particles of soot and other pollutants are having a far greater effect on the planet's hydrological cycle than previously realized, directly affecting fresh water availability and quality. The aerosols are a mixture of sulfates, nitrates, organic particles, fly ash, and mineral dust, formed by fossil fuel combustion and burning of forests and other biomass. http://ens-news.com/ens/dec2001/2001L-12-07-06.html Using biodiesel gives substantial reductions of unburned hydrocarbons (-93%), carbon monoxide (-50%), and particulate matter (-30%), ie soot - NBB. So is using biodiesel rather than dinodiesel helping the water situation more or less than your washwater is polluting it, d'you think?
