Posted By Martin Hartland Paul We also use a floor cleaner in the way you descibe. We have a consent to discharge the floor wash to the foul sewer from the regional sewer network. Give them a call and they'll issue you a "small volume letter" which will cover you for discharges of small low hazard amounts to the foul sewers. They may want to come and look at the equipment you use and the discharge point. Regards Martin Hartland

Posted By Dave Nicholls Paul, Apply for a consent to discharge to foul sewer and you find that your water company will probably able to help for a nominal charge. The Environment Agency only issues consent to discharge licences for surface water drains/storm drains (whatever you know them as). You need to talk to your water supply company - this will also be the company that runs the foul sewer network in your area. However, I do agree with the previous post that advises you to contact the EA for regulatory information. For example, my company have recently been granted a discharge consent to foul sewer for 72 cubic metres of effluent per day containing many 'nasties', Hydrogen Peroxide and Ferrous Sulphate to name a few. The point, is that, before the discharge consent was granted, we had to store this effluent on site and then pay £2000 per week to have it tankered away. Although a capital cost of £25000 was required to install a pumping and dilution system in the first instance, the savings spoke for themselves. If you are granted a discharge consent, then be prepared to implement a strict monitoring regime of what you are discharging - you need to be able to prove that you are adhering to the consent limits set by your water company. Hope this helps

Posted By Dave Nicholls Paul, David is right, a typo error on my part - I should have added the word 'probably'to my initial statement!
