Septic Tank Reviver (STR)

Composed entirely of naturally-occurring microbes, which have been air dried for longer shelf life, STR prevents smells, clears out congesting gels and will de-fat your septic tank and soakaway over three weeks.

STR is a remarkable product. It’s like sending a detachment of crack troops to boost a tired army.

As modern man’s eating habits have changed (see Changes in modern effluent) the demands on municipal sewage works have increased. This rings true for septic tanks too. While sewage works are equipped to handle these changing loads, however, the average septic tank is not. Cumulative distress depletes the efficacy of the benign bacteria working in your tank. As the population of microbes struggling to digest the excess of fats decreases, the soakaway clogs, the chambers start to smell and overflow, and the system dies.

An inoculation of STR ‘soldiers’ will change all this.

How? STR is packed in soluble pouches that dissolve quickly in water. Upon soaking, the air dried microbes ‘wake up’ from their suspended animation and, kick-started by the incorporated nutrients and enzymes, voraciously attack the biological effluent into which they have been introduced. The microbes rapidly proliferate, increasing their biomass in proportion to the nutrient supply. As they ‘eat’ their way through the congested sewage they break the solids down into harmless, natural substances (namely water and biogasses). They work thoroughly through the chambers cleaning the gummed up weir pipes and bends, dissolving the solidified surface crusts and the biological detritus in the tank. Most importantly, they break the ‘gel’ choking the soakaway, reviving the system and enabling it to perform at its peak.

STR is supplied in a very easy-to-use soluble DIY pack. It is safe to use anywhere and can be dosed directly into the septic tank or simply down the toilet bowl.

Fast fact: A thorough mechanical ‘pump out’ will cost more than STR treatment and will need to be repeated as it only removes the contents of the tank and does not decongest the all-important soakaway. Many tanks are inaccessible and considerable damage to fences and gardens may be incurred – plus there’s the mess and the inconvenience. By administering a maintenance dose of STR every three months (or as required) to boost the microbial population eroded by harsh sanitizers and excess fats, your system will remain healthy and trouble free indefinitely.

STR attributes

  1. Degrades human sewage and controls sewage odour.
  2. Non-toxic, non-chemical and entirely safe (greatly improving the quality of effluent to the ground water table and natural environment).
  3. Prevents blockages and build up of sewage crusts.
  4. Allows a steady stream of benign fat-degrading bacteria to enter the soakaway drain, preventing fats from sealing up seepage channels.
  5. Cleans out fats and greases from the soakaway as well as the tank and pipes in the system.
  6. Establishes a viable microbial biomass in the septic tank for long term effect.

Dosing

STR should be regarded as a preventative rather than a curative treatment. Routine maintenance dosing – to replace the ‘soldiers’ knocked out by biocides and so on – will pre-empt overloading, FOG and crust build-up; prolonging the trouble-free life of your system for many years.
