    Can anyone help? What do I do about biological contamination in a water barrel. The water comes off the roof, and we cleaned out the barrel recently after noticing a nasty smell, and the build up of black slime on the edges of the container. The water is used for toilet flushing and general cleaning while we wait to have a well installed, however it is unpleasant to use at the moment as the odour has returned. Anyone know what it is, or what to do about it - I guess the question will be relevant to anyone using rainwater, or green water.

    Thanks in advance!

    Do you have lid on your barrel?

    Yes, have lid. There is an overflow chute from the side at the top which lets in a limited amount of light.

    Bird poo will add to the water some organic material for micro-organisms to get to work on. Warm water will do this process faster than colder and I would go for an underground store with a small pump. So long as you are not going to drink the water a tiny ammount, literally one or two drops, of bleach every week will likely solve your problem.

    In india they have found that keeping water in copper jars for 24hr + reduces bugs and illness. Use a copper tank or fill the tank with short lengths of scrap copper pipe.

    That's interesting Patrick! Stringing a copper wire along your roof ridge rids your tiles of moss build up, I guess it's the same principle.

    There is a commercial product made of copper and fixed along the roof ridge that claims to keep your roof clean - forget what it is called but came up in google search for copper rooves.
    Check out "The New Autonomous House" by Robert and Brenda Vale. Plenty of insights into using/storing rain water for a range of domestic uses.

    Okay, I have some copper pipe fixings somewhere. I'm going to put those in the water barrel.

    Do you have a filter between the downpipe and the tank? For a filter I am using a tank filled with some sort of baked clay gravel - it is a pond filter that I picked up at the dump. This clay gravel is porous, and so has a big surface area available to bacteria. The bacteria eat the bird shit and whatever else comes down the downpipe. In a year or so, I have had no smells at all. I should also mention I have mesh over the top of the gutters to keep out moss, and just before the filter, I have a 'dead leg' for any sand or grit to fall into. I empty the dead leg every few weeks.

    Good luck.

    On "Gardeners question time", a lady wrote in to thank Bob Flowerdew about his suggestion to use goldfish in her water butt to keep it clean. Apparently they have now been in there for ten years.
