A properly maintained system discharges effluent (water), of a very high standard, often exceeding the minimum standard set by the Department of Health.
The minimum standards are:
- BOD5 (Biological Oxygen Demand over 5 days); less than 20ppm (parts per million),
- SS (suspended soils), less than 30ppm,
- Ecoli, less than 10 per 100ml, and
- ‘Free Chlorine’ count of not less than 0.5 ppm.
If, at any stage, the system is not achieving these results we must advise you of the problem and ask your help to overcome it.
