Sewage treatment/soakaway options

[Jammyb90]

I live in what used to be a very old farm house which was surrounded by fields, the house is now enclosed by privately owned businesses and workshops. My septic tank (which i will be upgrading to a treatment plant) has an outflow which travels across the business park. Ideally I could install a new system and outflow which does not cross any boundaries and stays within my property's borders. I'm trying to understand how realistic this idea is as theirs a lot of mixed information online. Is it acceptable to use a soakaway for a treatment plant? Do I have room in my garden? Regulations? Distances?

Any sort of help, guidance or info shared would be greatly appreciated.

Thanks

Need to do a percolation test before anything else, no Soakaway will work if the ground conditions are not suitable, you'll simply end up with a waterlogged garden and a backed up system.

If ground is suitable, then see Part H of the Building Regs for further guidance. https://www.gov.uk/government/publications/drainage-and-waste-disposal-approved-document-h
