@Russell griffiths thank you very much for all the information, much appreciated. What type of concrete did you use please? The reason why I ask is that I used semi-dry concrete on another job, and it was permeable and just let the water in around the tank I had put in. Cheers Dave

@Russell griffiths thanks a lot for the photos Russell ! Am I right in thinking that you created a concrete box around the tank and then filled that with concrete? Cheers Dave

@ProDave hi prodave,which STP did you choose for your site, cheers Dave

@Russell griffiths morning. Did you dig a hole, insert the treatment plant and then encase it in concrete? Or build a concrete box to put the plant in, then place reg tank in that, and then fill that with concrete? Thanks a lot, Dave

@Russell griffiths that’s impressive ! What type of concrete did you use for the “box”? I forgot to say, water table is almost up to ground level at wet period in winter cheers, Dave

Cheers Russell. Really appreciate your post. Can you give me an example of a “really good plan” ? My main concern is lateral hydrostatic loads, and how to prevent them. Cheers, Dave

Hi folks has anyone got any experience in installing a Clenviro Sewage treatment plant in a high water table? If so what thickness and type of concrete did you use please? Thanks Dave

It’s often not easy to do, and very expensive to boot. It’s a ludicrous requirement for a single dwelling like mine that in the middle of a 2 acre plot.

@JamesPthank you very much for replying, sad that Joe has passed, always enjoyed his posts which were extremely helpful. Thanks, A

@joe90 hi Joe how is your Vortex going, I am just about to commission mine, cheers, A

@JamesP how is your WTE plant going now? @joe90 cheers

Hi folks. On inspection the seals from the risers in 3 inspection chambers were found to be missing, hence the water ingress. The seals were inserted and glued into position. We then poured about 30cm of concrete around the entire inspection chamber. Problem no solved, no water ingress. Thank you for your help.

Are there makes of inspection chambers that are one piece r and designed for high water tables?

My builder is suggesting concreting in the inspection chambers to prevent water ingress. Does that sound reasonable? Thanks for your suggestions so far.

Not sure what a TP is @ProDave
