I live in a village with no mains drainage. A company has dropped off flyers offering to swap septic tanks for sewage treatment systems FOC. They claim the phosphate credits, you get your septic tank replaced.

Has anyone here swapped their septic tank for a treatment plant?

Our current tank is probably as old as the house (so 50+ years). We have had a couple of issues which have been resolved by water-jetting the pipe to the drainage field, but other than that it has been fine. My concern is that we might move from a system that causes us very few problems to a "new improved" solution which might not work as painlessly.

So - any experiences would be appreciated. I'd be interested to hear of any teething problems your system might have had, and how they were resolved.

The main downside appears to be that the treatment system has some running costs associated with it (electricity and an annual service) which the septic tank does not (they both need to be emptied at similar intervals).

The upside is that we get a new system to replace the old one which could be nearing end of life. It will also produce cleaner output, which I guess can only be a good thing.

Yes made the change in late 2021. We were doing work that needed a new sewage connection. In doing this we established that the existing septic tank wasn't working properly & appeared somewhat unconventional. We replaced with a Clearspan unit. As legisaltion on septic tanks continues to seem to tighten it seemed to be a sensible thing to do to replace.it & be done No issues to date. A FOC installation seems very generous & too good to be true..

I would also be very suspicious - surely there aren't sufficient credits available to get any reasonable return on what will be quite an expensive installation?

Check the small print carefully!

This is becoming fairly common standard practice in nutrient neutrality affected areas without official credit schemes, of which there really are not many across the UK. It's one of those few cases where the offer really is not too good to be true. However, standard advise applies of undertaking your due diligence on the PTP system (and choice) on offer, warranty and the contractor who will undertake the work.

What is effectively taking place is a contractor has found an existing gap in a (presently, very grey) market to effectively be a middle man on the transfer of phosphate credits from existing sites to new sites. The benefit to the contractor is that they simultaneously gain two sewage private treatment plant installation contracts. The benefit to you is that you receive a new PTP. However, the real benefit is to the client of the new site who requires their own PTP and (desperately) requires phosphate credits to offset their own installation. It is the latter who pays for all of the work on both sites.

There is also a market for you to undertake the sewage system upgrade work yourself and through doing so, offer to sell the phosphate credits that arise to a new development. There are online broker services that can assist you with this and obviously take their cut.

Thanks for the feedback. I think the key factor will be who is completing the work and what warranty / guarantee they provide.

Hi,

I live in Cumbria and my neighbour and I are considering signing up for the septic tank replacement scheme. I am wondering if you finally went ahead with your tank replacement and what your experiences of the replacement scheme and the new equipment have been.

Any thoughts you would like to share on this subject would be gratefully received.

Thanks.

Interested here too. My septic tank is past its best and looking at plant options.

The whole thing has gone quiet. The original commercial company had the wind taken out of their sails by a local authority / grant funded scheme which is planned to go through the area offering free upgrades - but that scheme is moving very slowly. Slightly frustrating but a not a problem as our tank is still working fine.
