The traditional septic tank may seem very cheap initially, however, you will require a soakaway to discharge the effluent because the final effluent is not clean enough to discharge into a watercourse or ditch etc.A soakaway for a septic tank can be problematic because a sufficiently large area of land is required, and not all areas are suitable for a soakaway.The life expectancy of a soakaway from a septic tank is around 10 years, compared to 25 years from a packaged sewage treatment plant.Soakaways are prone to blocking from a septic tank due to the unclean effluent.The Bio-Pure may therefore be a better solution for your wastewater treatment and possibly cheaper than installing a septic tank.
The three stage system is quite similar in price in terms of purchasing and installing the unit.However, some three stage units require concrete backfill for installation which can be quite costly.The Bio-Pure does not need concrete unless it is preferred. The three stage system will require emptying once a year because solids are stored, whereas the Bio-Pure will need emptying every 3-5 years.Some three stage units may contain moving parts.The Bio-Pure does not, which means that it can not break down.
