CAN I USE BLEACH AND DETERGENTS

The original concept of a septic tank was to use natural anaerobic biological action to produce an effluent with a low concentration of solids and combine this with the use of gravity to pull solids to the tank base.

Modern septic tank systems as shown tend to be designed on the use of gravity as the main process of separating the solids from the sewage effluent.

Because we use a significantly higher use of water and household cleaners in our modern life it is very difficult to achieve a good anaerobic action in septic tanks. So if you have a modern tank unit, using bleaches and detergents (in normal quantities) should not present any adverse effect. With more traditional tank systems (see The Operation of a Septic Tank) you are more susceptible to problems due to bleaches and detergents. If the tank is of small capacity or of only one chamber then you may find the soakaway will have a reduced lifespan.
