Downpipe water drain away options

Sep 26, 2006 2 Replies

I was hoping to avoid digging a soakaway for a new downpipe on my house (the existing downpipes arent sufficient in number due to an extension on my house a few years back). The company who are fitting my new soffits, bargeboards, and guttering advised that I needed an extra downpipe and recently a very heavy rainstorm proved this....



Is it feasible to obtain a large water butt and have all the rainfall from the new donwpipe collect in there, and then just empty periodically - would a heavy rainfall fill it too quickly in one go, or could it last a few days before being emptied.... The other option is to locate the new downpipe adjacent to the kitchen sink drain, although I know this is technically breaking local water regs, in terms of dumping rainwater into the local drain (?).



Any one have any past expereince in this?



Thanks, Nick


Ask the Met Office for the highest recorded dialy rainfall for your area. Multiply that by the plan area that will use the downpipe to get a daily rainfull volume. Work out the longest time that you might be away. Multiply that by the daily rainfall volume. Get a tank at least that big but preferably much bigger. It's possibly called a swimming pool.

I've got the largest the sheds sell. It fills in around an hour of moderately heavy rain from just half of the house roof, or faster in real down-pours.

You can ask the local sewage company for permission. A friend did this when building an extension, and much to my surprise, they said yes.
