Evogen Septic-Plus – Environmentally-Responsible Biological Septic Tank Treatment – Encourages Breakdown and Tackles Bad Odours Within The System - 12 Water Soluble Sachets, 1 Year Supply

These are a great way of improving the performance of a sewage treatment plant. One bag a month seems to help with breaking down stubborn waste. Seems to be a cost-effective way of minimising sludge build-up and keeping the aerobic process going. Eco-friendly solution. Easy to use. Just drop down a toilet or pop into a connected drain.

My parents used to have problems with the pipes quite often. They are using this product for a few months now and ever since everything works well with no unpleasant "surprises"

Used this for my septic tank and OMG The difference was outstanding. Best product I ever used and I have been trying a lot of them. Highly recommended 10 out of 10.
