Posted By A Campbell Polo, we have a similar problem in the event of the sprinkler systems engaging. We have on call contractors in the event of run off to assist in pumping equipment to help prevent excessive flow into the brook and redirect into the watercourse systems. Although in dilute form we expect no environmental harmful substances be involved. Not sure how deep you intend to go into this subject as normally part of a business continuity planning scheme which your insurance company may have an imput?

Posted By DPK Polo This issue should be covered within your Environmental Management System, obviously that is if you have one etc etc. Dependent on the lie of the land at your site it would be practically impossible to contain half a million litres of any liquid unless you have very large interceptor tanks or the whole site is bunded, which i doubt as this is usually reserved for COHMA type sites. 1 million litres then you can forget it! So the action you may want to consider is how do we prevent the occurrence and if it does happen, how will we reduce the affects of the possible pollution. Again with cost in mind look at the options of sluice gates at the immediately affected drains, another option is inflatable bungs which you place into the drains. But then what do you do with all that collected water, it totally depends on what it is polluted with! If it were i that was dealing with your issue i would focus 75% on the prevention of the incident and 25% on the reactive measures as the cost of them could be astronomical. Hope this helps, if you would like to chat (as i dislike typing) then feel free to call. Regards DPK

Posted By martinw Polo if you are going to get in touch with the Environment Agency have a look at PPG 18: http://publications.envi...O600BBUD-e-e.pdf?lang=_e which gives guidance specifically for pollution planning in terms of control of fire water run off. Hope this helps Martin

Posted By Kenneth Patrick You either need a 1 million litre container perhaps created by securely bunding your entire site. Or you could have an environmental management system. Ken

Posted By SPARKSJ Sorry I should have been more specific about what Environmental Innovations actually do, they DO use the drain as a containment system. Rather than working against gravity with spill-kits they allow the drain to do what it was meant to do, but prevent it from getting out into the environment. This buys you time to get the liquid sucked out and re-cycled. The same technology in portable guise is used by the fire service to lock off a drain prior to using foam or water.
