    Just tested the rain and its coming out at 3ppm!!! You could use that on windows!

    I filled up a cup of it but it had a couple of solids in the bottom. What do you use to filter them out? A cloth? Or a pre-filter?

    To collect the rainwater is a simple task of diverting the downspouts of your guttering to a storage tank. It is essential that the tank does not allow light through to the water to prevent algae growth, so a black container or underground tank works best. To keep the TDS level to a minimum, the roof and guttering should be maintained so as to be free of dirt and sludge.
    Rainwater should pass through a filter to strain out larger contaminants like insects and leaves before entering the tank. A submersible pump can be placed inside the tank to pump the water through one or two DI vessels to polish the water. Some window cleaners that collect rainwater use the water without even passing it through a DI vessel since the TDS level is so low anyway. It’s good practice however, to use water at a TDS level of 000 and with such a low TDS level, the resin will last a long time anyway.
    Of course, it doesn’t rain everyday so the tank size should be large enough to store water from rainy periods which can be used during drier periods. An underground tank size of 3000 or 4000 litres would be ideal. Another method could be a modular system of smaller water butts connected in series above ground.
    We mentioned earlier that a house roof may collect 80,000 litres of rainwater each year. This is based on the total surface area of a typical 3 bedroom semi detached house. Obviously, the larger the surface area of the roof or collection surface, the more rainwater collected. For every inch of rainwater water that falls on a surface of 1000 square feet it is possible to collect approximately 600 gallons of water.
    80,000 litres of rainwater per year would be sufficient to fill a 300 litre tank each working day of the year. This could dramatically reduce water bills and with the much publicised, continual water rate increases, we cannot afford not to save our water and subsequently save money and the environment.
    Being green is also a good selling point. Nowadays customers appreciate a company that is responsible towards the environment. Even if window cleaners were to be given exemption, customers are not always comfortable about having their windows cleaned with a water fed pole system during a hosepipe ban. Explaining that you use harvested rainwater would no doubt resolve the problem.
    There’s no doubt about it, whatever your water usage may be, the investment of setting up a rainwater harvesting system would soon pay itself off. Interestingly, Enhaced Capital Allowances (ECAs) enable a business to claim 100% for rainwater harvesting equipment.

    Nice post rc just about says it all. I always polish it through so and just got rid of my very first one litre that I've used for months. Heavy rain is best to collect and rain when its foggy I noticed last week is filthy and grey in colour do would definitely benefit from a good filter system and di.

    Used 1000 ltr ibc tanks are cheap as chips and are ideal to store rainwater. ;)

    I pay around £30 for 1000 ltr ibc's as 210 ltr water butts cost about the same so is a no brainer for me.

    I haven't seen the black ones for that price. Can you paint them? Or do you have a link?

    I have white ones as not bothered if they start to go green to be honest as only takes minutes once every year or so to pressure wash them out. They are also covered in tarps so helps a bit and no I've not tried painting them black .

    Search ebay for someone selling ibc's local to you as delivery most want an arm an leg to deliver anyway. You may be lucky to get blue or black ones but be aware depends what they have been used for if you can get them clean.
