soakaway separation distances

    Hi all,
    I'm in the process of getting planning for a house. I am wondering are there separation distances required between a proposed soakaway and nearby well/percolation areas etc? Surely a soakaway is just filled with rainwater which cannot interfere with these items. Also, to the front of my proposed house is a road surface water drain. Am I automatically allowed to run my rainwater into this drain if I decide not to make a soakaway?
    thanks

    Yes. I think BRE DIGEST 365 is what the councils still use but you’d have to get tour engineer to confirm with the drainage department prior to any works.

    No, you have to deal with your own surface water runoff on site. Only if you can't then you're allowed to discharge to the public system.

    I've seen plenty houses that use a soakaway to drain the roofs, but let the water from the drive go into the public sewer to the front

    Are they legal and compliant though?
    SUDS requirements would be relatively new, well 15 years or so.

    Also, each site is different, you have to check what your site has permission for and that will involve dealing with the drainage department, they will approve your plans from the engineer.

    There are three proposed new houses in my vicinity, the planning drawings online which show their driveway gullies, along with an aco drain to the front, discharging into a public sw sewer to the front of the house.

    maybe your local authority allow it? personally i dont know any that allow that currently without some kind of on site attenuation.

    have these houses been granted permission yet, if they have, is there any reference to storm water in their conditions of planning.

    Two have, the other is only in a few weeks. Their conditions say that surface water cannot discharge onto the public road. After all, it only makes sense the council would allow you to send surface water to an existing big sewer running down the road your house is on.

    Green field sites turning into developed hard surfaces are significant reasons were having so many problems with flooding these days, so it doesnt actually make sense for councils to allow more unhindered storm water to be focused into sewers. These sewers have to discharge into a watercourse somewhere, so all thats happening is that these watercourses are becoming over whelmed quicker.

    but hey, if your council allow an unhindered connection to the public stormwater sewer, go for it.

    Most likely just planning drawings.
    Keep an eye on the grant of permission if granted.
    One of the conditions will be to contact the area engineer for drainage and agree on writing the proposal. This proposal will most likely be suds and treatment of surface water on site.
