Thanks. Yes it will have a pump. Thanks everyone for all the input. Much appreciated! Sounds like I don't need to worry about the depth of the tests, so will go forward with the quote.

Thanks for all your responses so far. To answer a couple of questions, I believe the reason for going deeper was to do with checking the integrity of the existing septic tank. The perc results were poor, and the holes actually gained water during the test. The garden itself is tiered, with the house sitting lower than where the tests were conducted by about 1 ft The solution proposed was to install a treatment plant, which will pump any liquid after treatment to a soak away on a higher bit of ground. I was happy with this solution, but after the feedback from other drainage companies im not sure whether this solution is based on an inaccurate test in the first place!

Hi everyone. Would appreciate some advice. I had some perc tests done to judge how large a soak away I required. These were done at a depth of 1.8m at the drainage companies suggestion. After completion of the tests I messaged some other drainage companies to get quotes for remedial work, and one stated that perc tests should not be deeper than 1m. Is this correct? What's the potential impact of going deeper than 1m?
