Hi all,
To cut a long story short our septic tank soakaway has packed in, again! My thinking for this happening again only 4 or 5 years after replacing the last soakaway is that in the winter the water table is high causing the effluent to remain static in the soakaway and turning into sludge meaning long term damage to the soakaway leading to thermal failure.
What I am planning on doing is replacing the septic tank with a sewage treatment plant and pumping the effluent to a raised soakaway. Ive got a good idea of how to construct the raised soakawy but Im struggling to find anywhere that actually sell the necessary parts to construct the field drain. I was intending to use 110mm perforated twin wall pipe. The pipe is easy enough to source but I cant find the parts, should I just use normal 100mm soil pipe parts?
Any thoughts would be much appreciated.
