Hi,
Grateful for advice. We had a new sewage treatment plant installed to replace an old septic tank a few months ago. Garden is on a slope so it now discharges, via gravity (i.e. no pump) to a drainage field. The drainage field has an inspection chamber just before it starts and I am worried about the water level being too high- it is ABOVE the top of the pipe draining into it . How can it be draining properly? Is this ok? Installer not easy to get hold of. I always had concerns that this area of land was wet and boggy in winter - but the perc tests done in summer were ok so installer went ahead. How can it be working if the ground level of water is this high??
Thanks for any insight
