Standardisation in the area of Water quality protection

Mr. Kago Setiko
Botswana Bureau of Standards, Botswana


Standards are important because through them health and safety of communities is assured. Water is an important commodity in human life and it makes about 70% of the human body and hence the need to develop water quality standards for human drinking water, irrigation water and water for livestock and poultry. Botswana Bureau of standards (BOBS) through Water Quality Technical Committee develops water quality standards which are either compulsory standards or voluntary standards. Compulsory water standards are regulated by BOBS and these are: Drinking water – Specification (BOS 32:2009), Bottled natural water – Specification (BOS 262:2011) and Bottled water other natural water – Specification (BOS 143:2011). Voluntary water standards are not regulated by BOBS but may be regulated by government departments such as Ministry of Agriculture and Department of Waste Management and Pollution Control. Examples of voluntary water standards include Water quality for Irrigation (BOS 463:2011), Drinking water for livestock and poultry (BOS 365:2010) and Waste water – Physical, microbiological and chemical requirements – Specification (BOS 93:2012).
