Using EM in Septic Tank Systems 

Using EM to control your septic tank system is a cost effective method providing an environment friendly solution to the problems of odour and contamination from waste disposal.

How EM will help improve your septic tank system?

Your septic tank is the collection point for household sewage. Waste is collected and settles giving microbes a chance to break down the organic waste. The micro-organisms also ensure the liquid stays fluid and help keep foul odour to a minimum. EM is a microbial inoculant, which contains live bacteria which need organic matter to continue to multiply. In a septic tank situation there is always enough organic matter for the micro-organisms to feed on. By adding EM-1® your septic tank will stay working the way it should.

Common Septic Tank Problems

  • Anaerobic environment
  • Reduction in breakdown of organic matter
  • Increase in bad bacteria and pathogens
  • Foul odour
  • Increased sludge
  • Increase in rate at which tank needs to be cleaned out

Why these problems arise?

Modern cleaning products e.g. disinfectants, bleaches and detergents, are designed to kill the bugs i.e. bacteria.  Regular use of these chemicals can upset the biological balance of your septic tank by killing off the micro-organisms that do the work.  Extremes of temperature can have a similar effect.

Why you should use EM in your septic tank?

EM is a natural solution that works by increasing the microbial diversity of the system.  As more and more of us continue to use antibiotic soaps, and increase the use of bleach and other disinfectants, not to mention the intake increase of pharmaceuticals, the lifeblood aka ‘the biological balance’ of any septic tank system is put in jeopardy as the microbes start to die. The only way to revive it is to inoculate it with a strong, live culture of microbes like those found in EM.
