Since we were digging up the places and given that we are not connected to Mains sewage, it seemed appropriate to install a new sewage treatment plant. The house was originally served by a septic tank, and although we can use a septic tank, thinking ahead the way legislation is going, it’s better to have a full sewage treatment system installed. This allegedly outputs water fit to drink……but I’m not going to try it!
The leading brand seems to be Kingspans Clargester, which is both expensive and in my opinion (but what do I know!) overly complex. Basically a sewage treatment system has three tanks, the first a settling tank, the second an aeration tank and the third another settling tank. Anaerobic and aerobic microbs dine out on the poop coming in within the three tanks to create clean water coming out. The Clarge using rotating discs to aerate the second tank driven by a motor, belt and bearings, which in my humble opinion in a nasty environment is likely to go wrong over time. To get them fixed is also eye watering in every sense of the word. So, looking around I wanted a simple system, easy to fix myself should the need arrive, achieve the same standard of water purity output and be cost effective. I have chosen a Marsh system. This uses a simple grid in the bottom of the second tank hooked up to a ‘fish tank’ type pump that bubbles air throigh the juices. It carries all the same certification, and is dead easy to fix should it go wrong with the pump being outside the tank (Clargester. Had everything inside the tank) best of all it carries a long guarantee and is about 1/4 the price of a Clargester!
There are various sizes of tank, depending in how many people it serves……I was actually surprised how little difference there was in price between the ideal tank for my property and one larger Units. I decided to get a much larger unit, not only will this ensure that it’s future proofed for any further development at the site, but means the stuff goes through it slower initially giving the bacteria more time to chew on things.
Big ild thug isn’t it!
Tank installed, it’s concreted in, and will be backfilled with soil
The black conduit is to carry power and water to garden sheds in putting up in the garden.
More grading to be done to alleviate the mount Everest slope. You can see some of the soil that’s starting to be ‘dumped’ to o this.
