Neither have been allowed for years. That's why I had to put in what you
call a 'mini sewage works' back in the noughties.. had a septic tank
discharging into a soakaway, they said 'New house? Cant use that'



Mini sewage works: septic tank with mechanical agitation and maybe air
bubbled through the sewage to help it to rot more, discharging liquid
which is cleaner than for a septic tank, into either a soakway or a
watercourse (the latter *is* allowed in the 2020 regs).

Other methods are allowable. I.e. reed beds etc etc


In Australia mine is a tank that overflows into an absorption trench and
every year I have to pay a fee "to operate a sewage treatment works"
